8 Things You Should Never Do To your TV

0:00 You've been sabotaged by TV manufacturers and they're counting on you never figuring out why your screen dies at 5 years instead of 15. Today, I'm exposing 15 tricks that destroy your TV in silence and why the industry buries this information. These fixes cost nothing, take seconds, and they're exactly what I do on my own television. Stick around for number one. It's the heat mistake that's kept my 2015 television still running today while millions of identical sets are dead in landfills. Let's get into it. Number 15, the spray mistake that destroys $400 screens. Here's what manufacturers don't tell you. Spraying cleaner directly on your screen is one of the fastest ways to kill it. I've opened up televisions where liquid got inside the bezel and

0:45 corroded the connectors. The damage looks catastrophic and the screen's still sitting there looking perfect from the front. You just can't use it anymore. Here's what's happening. When you spray cleaner on the screen, it doesn't just wet the surface. That liquid runs along the edges, seeps into the gaps around the panel, and finds its way to the circuitry behind the glass. Modern TV panels have anti-glare coatings that aren't designed to handle moisture. The coating breaks down. The liquid eats through solder connections. And inside that sleek frame, you've got a dead set. Here's the fix and it's almost embarrassingly simple. Use a dry microfiber cloth. That's it. If the screen [music] has a stubborn mark, dampen the cloth slightly with distilled water, not the spray. Wipe gently. The whole process takes 30 seconds and costs

1:32 you nothing. A technician charges $200 to replace a corroded panel. You just prevented that with a cloth. This is exactly what I tell every homeowner and what repair shops never mention because they'd lose thousands of dollars a year if people actually knew this. But here's what most people miss. Cleaning the screen is just the beginning. There's a thickness setting on your television that's slowly suffocating your screen right now. That's next. Number 14, the thickness trap that ages your screen faster. Now, the next tip is something manufacturers really don't want you knowing. This one makes their $200 service completely worthless. Your TV has a brightness setting, but that's not the real problem. The problem is that most televisions ship from the factory maxed out. And that's intentional. Think

2:19 about what happens when you get a new TV home. It's glorious, brighter than anything you've ever seen, crisp, vivid. You think this is normal. It's not. This is showroom brightness. This is the setting designed to make the television look amazing under fluorescent lights in a warehouse while other sets around it competing for your eye. At home, that brightness is crushing your screen. Here's what's actually happening. Your OLED panel or LED backlight has a lifespan rated in hours. When you run brightness at maximum, you're not just making the screen brighter, you're accelerating the chemical degradation of the pixels. You're burning through years of lifetime in months. I've tested two

3:05 identical televisions side by side. One set to reasonable brightness, 70%, the other maxed out at 100%. After 2 years of identical use, the bright one shows visible color shifting. The other looks new. Here's the fix. Go into your picture settings. Find brightness or backlight. Set it to 60 to 70%. Your eyes adjust in 48 hours and you'll never notice the difference, but your screen will thank you with five, sometimes eight extra years of life. That's the difference between a TV lasting 5 years and one lasting 13. A repair shop charges $120 per visit just to recalibrate picture settings. You just did it free and prevented screen death at the same time. But even if you do

3:50 this perfectly, there's one mistake almost every homeowner makes with the power button. That mistake is costing you more than any settings adjustment ever will. That's next. Number 13, the overnight mistake that bleeds your wallet. And speaking of things manufacturers bury in the manual, wait until you hear what's next. I've been servicing televisions for over 20 years. In that time, I've seen one error destroy more screens than any hardware failure. People leave their televisions on overnight. Think about what this does. Your TV is designed to shut down. It has power saving modes. It has sleep timers. All of those exist because running a television continuously is like running a car engine for 16 hours a day. Eventually, something gives. But, here's the part that makes manufacturers

4:36 happy. When you ignore the sleep timer, you're wearing out your display, your power supply, and your cooling system simultaneously. And when something fails, you call a technician, or you buy a new TV. Either way, they win. I had a customer in Portland last month. Older gentleman, left his television on from 6:00 a.m. until midnight every single day. Never turned it off. He thought leaving it on low volume was fine. His screen developed what's called image retention. Permanent ghosting from the news logo sitting in the same spot hour after hour. The repair, $850. The solution would have been hitting the power button. Here's what's happening inside. Every pixel on your screen has a lifespan. When current flows through it continuously, you're not just using that

5:21 lifespan, you're accelerating it. Your power supply heats up, your backlight dims faster, your cooling system works overtime. All of this happens silently, invisibly, until one day you turn on the TV and half the screen is dim, or the picture goes purple. Here's the fix, and you already know it, you just forgot about it. Use your power button. When no one's watching, turn it off. When you leave the room, turn it off. Better yet, set the sleep timer to 30 minutes. Your TV goes dark automatically, no thought required, zero cost, and you just added years to the screen's life. I've replaced over 300 power supplies in my career. You know what they all have in common? They failed in televisions that ran constantly. In sets that got a power

6:06 button, they run forever. Now, we're getting to the tips that really separate TVs that last 5 years from ones that last 20. The next one is critical. Number 12, the blocked vent trap that kills silently. A retired couple in Sacramento called me last month about this exact problem. Their television was making a high-pitched noise. One week later, it died completely. What I found inside made me furious, and it was completely preventable. The vents were sealed, completely sealed. Here's something the industry hopes you never figure out. Televisions need to breathe. Your TV has vents on the back, on the sides, sometimes on the bottom. Those aren't decorative. They're the only way heat escapes from the electronics inside. And when you block them, you've just created a slow-motion disaster.

6:53 Think about the location of your television. Wall-mounted over a shelf, set in a cabinet, leaning against the wall in your bedroom. How much space is behind it? 6 in? 2 in? 0 in? Every one of those decisions is slowly cooking your television. Here's what's happening. Your TV generates constant heat. The processor generates heat. The power supply generates heat. The backlight generates heat. All of that heat needs somewhere to go. The vents pull cool air from the room, push it across the hot components, and exhaust it out the back. When you block those vents, the temperature inside the cabinet starts climbing. 40°, 50°, 60° C. The capacitor start drying out. The solder joints start to crack. The processor throttles itself, which causes

7:40 picture stuttering. And then one day, usually about 2 years into a television that should have lasted 10, just stops. I've opened up televisions from cabinets where you could barely fit a hand behind the set. Every single one had the same problem [music] corrosion inside from trapped heat, capacitors bloated from thermal stress. It's like suffocating a living thing in slow motion. Here's the fix. Make sure there's at least 4 in of clear space behind your television. 6 in is better. 10 is ideal. And the sides, keep them clear, too. No curtains, no decorations, no furniture wedged in. If you've got your TV in a cabinet, leave the back open. If it has doors, make sure they're open whenever the TV is on. Install a

8:25 small USB fan that blows toward the back vents if space is really tight. The fan costs $8. The television costs $600. This is what technicians do on their own televisions at home. Make sure they can breathe. But, they'll charge you $350 for a heat-related repair without ever mentioning the airflow problem. Now, there's a setting on your TV right now that's pushing your screen harder than it was ever designed to run. And repair shops make thousands because people skip this one. Number 11, the showroom setting that ages your TV. This is the trick the industry really doesn't want you discovering. It makes their entire brightness adjustment service obsolete. Your television shipped from the factory with a setting called store mode or vivid mode or dynamic mode. Whatever the

9:11 manufacturer calls it, it's the same thing. The brightness is [music] aggressive, the contrast is exaggerated, and it's designed for one place only, a bright showroom floor under fluorescent lights. But, here's what's happening in your home. That same setting that made the TV stand out against 50 other televisions in a warehouse is now running 24 hours a day in your living room. It's pushing your backlight or OLED panel to maximum output every single second you watch. It's burning through the lifespan of your display at three times the normal rate. I've compared the degradation curves on two identical 75-in televisions, one running in store mode, one running in standard or cinema mode. After 18 months, the store mode TV shows visible color shifting in the blues and reds. The other looks identical to day one. That's

9:57 not luck. That's the difference between a TV lasting 5 years and one lasting 15. Here's what's actually happening. OLED E D pixels have a finite lifespan measured in hours. LED backlights have a finite brightness lifespan before they dim significantly. When you run vivid or dynamic mode, you're forcing the panel to output at maximum intensity. Every hour, you're burning through the lifetime. It's visible. After 2 years, you'll notice the picture's not quite as bright. After 5 years, it's dim. After 7, it's unwatchable. Here's the fix. And this took me years to convince homeowners to do because they all said the same thing, but the picture looks dull now. It doesn't. Your eyes adjust within 48 hours. Set your TV to standard

10:45 mode or cinema mode or movie mode. Manufacturers use different names. The setting exists specifically to run at home brightness. The picture will look slightly less vivid for 2 days. Then it becomes normal and your screen just gained 5 years of life. This is what I do on my own television. This is what every television designer I've worked with does on their personal [music] sets. But try to find that information in the manual. It's buried on page 47 and the manual is already in a drawer somewhere. A technician charges $190 to recalibrate your picture settings. You just did the most critical one free. But here's what most people don't know. Your television software is trying to kill itself right now and if you keep ignoring the warning signs, it's going

11:31 to. Number 10, the software trap that makes your TV useless. Now, this next one is something repair shops absolutely love. It makes their update your TV service worth hundreds of dollars to people who have no idea what's happening. Your television is a computer, and like every computer, it needs updates. But, here's what manufacturers don't tell you. Skipping those updates doesn't just make your apps slower, it makes them stop working entirely. I've got a customer, a gentleman in his 70s in Boulder, who decided updates were too much hassle, skipped every single one for 2 years. One day he tried to open Netflix. The app wouldn't launch, then Disney Plus stopped working, then YouTube went dark. 3 months later, eight out of his 12 streaming apps were completely broken.

12:18 He called me in a panic, thinking his television was dying. The repair bill he was quoted, $580 for a complete software reinstall. Here's what's actually happening. The streaming services update their apps. Those updates require newer software on your television. The apps are coded to work with specific operating system version. When you skip the update, you're creating a mismatch. The app's new code can't run on your old operating system. The app crashes, or it simply won't launch. It looks like the app is broken. It's not. Your TV's operating system just fell too far behind. And here's the conspiracy element. Manufacturers know this happened. They know that skipping updates creates frustration. They know you'll either call a technician or decide to buy a new TV. Either way, they're winning. Here's the fix. Go to

13:04 settings. Find system update or software update. Check for updates manually once a month. When an update is available, run it. Let your TV restart. The whole thing takes 10 to 15 minutes while you make coffee. Do this monthly and your apps will work forever. Skip it for a year and half your apps become unusable. This is exactly what I do on my own television and what I tell every customer. It's free. It takes 15 minutes and it prevents the expensive software failure diagnosis that doesn't actually exist. I've replaced the software on over 200 televisions that customers thought were broken. Every single one just needed the updates they'd been ignoring. Now, the next tip is one that makes me angry every single time I see it ignored because it's so simple and the consequences are so severe. Number

13:51 nine, the harsh chemical mistake that destroys coating. Be honest with yourself, kiddo. What do you use to clean your television screen? If you said window cleaner, rubbing alcohol, or paper towels, you're destroying your screen right now and manufacturers are counting on you doing exactly this. A homeowner in Albuquerque called me 3 weeks ago. Her television screen had streaks, permanent streaks that looked like water damage under the glass. The damage was done by Windex. She'd been spraying window cleaner directly on the screen for 6 months thinking it was just dust. The anti-glare coating came off in patches. The streak pattern showed where the coating had dissolved. The repair wasn't available. They don't restore coatings. You replace the panel. $940. Here's what's happening. Modern

14:38 television screens have special coatings, anti-glare coatings, hard-coded surfaces designed to reduce reflections and improve picture quality. These coatings are polymer based. >> [music] >> Alcohol dissolves polymers. Window cleaner is mostly alcohol. Paper towels have fibers rough enough to scratch coatings under pressure. Every time you use them, you're slowly eroding the coating layer by layer. The coating starts disappearing. First, you see streaks, then haze, then areas where the reflection comes back because the coating's gone. It looks like the panel is damaged. Actually, the coating is being dissolved by your cleaning products. Here's [music] the fix. Stop using everything except a dry microfiber cloth. A microfiber cloth costs $3. If you absolutely must use liquid, use

15:25 distilled water on a barely damp microfiber cloth. Wipe gently. That's it. No window cleaner, no rubbing alcohol, no paper towels, nothing rough, nothing chemical, just a soft cloth. This is what television manufacturers recommend. This is what I use on my own sets, and it's what repair technicians do on their personal televisions while charging you $800 to replace the panel you destroyed with Windex. I've seen the damage countless times, [music] and every single case could have been prevented with a $3 cloth. But, here's something most people don't realize. The cables connecting to your TV are far more fragile than they appear, and yanking on them is one of the most common ways TVs stop working. Number

16:11 eight. The cable yank that creates fake failures. Here's something that'll make you angry. A week ago, a customer called me about his television. No picture, no sound, dead. He was ready to replace it. I opened it up. Nothing was broken. The HDMI port was just loose. One hard yank on the cable while vacuuming had bent the internal connectors. The fix took me 2 minutes. The fear it caused cost him a week of anxiety and the cost of a service call. Now, here's what the industry loves. >> [music] >> When you yank a cable, you don't break it visibly. The connector looks fine, the cable looks fine, but inside that DMI port, the tiny pins have bent slightly. Slightly enough to lose

16:56 connection. Not broken, just misaligned. And you think your TV is dying? I've replaced over 400 HDMI ports, antenna connectors, and power ports in televisions over two decades. You know what caused most of them to fail? Someone yanked the cable too hard, or pulled at at angle, or moved the TV while the cable was still plugged in and bent. Here's what's actually happening. These connectors have precious metal contacts that are positioned to exact tolerances. When you pull the cable, you're not just pulling the cable, you're pulling the connector. The port can't move, so the connector bends. The pins inside misalign by millimeters. Millimeters are enough to lose the signal completely. The TV looks and sounds completely normal until you try

17:42 to use that port. Then you get no picture, or pixelated picture, or audio dropouts. It looks like a hardware failure. It's not. It's a bent connector inside a port. Here's the fix. Treat cables like they're delicate. They're not, but treat them that way anyway. When you unplug something, hold the connector body, not the cable. Pull straight out, not at an angle. If you need to move the TV, unplug all cables first, move the TV, then reconnect. And use cable management. Velcro straps, clips, anything to keep cables from being tugged. Connectors cost $15 to replace. Cable management costs $5. I'm telling you which one I recommend. This is what every television engineer does with their own sets. But, here's what they don't tell you. There's a

18:28 brightness setting that's doing damage silently every single day. Number seven, the maximum brightness trap that kills screens daily. Now, here's the part most people never think about. Even if your TV is set to reasonable brightness in general, what about when you're watching football or a movie? There's a mental habit that's destroying millions of screens right now. The habit of cranking brightness to maximum for better picture. This is one of the fastest ways to age a television. I've seen it happen. Someone watches a particularly dark scene. They adjust brightness up. They forget to adjust it back down. Six months later, they mention the picture doesn't look as bright as it used to. By one year, it's noticeably dim. By two years, the entire screen has a dull,

19:14 washed-out quality. Here's what's happening. Every pixel on an OLED panel, every LED backlight on an LCD TV, has a finite brightness lifespan. It's measured in hours of maximum output. When you run brightness at maximum, you're burning through that lifespan at the fastest possible rate. The brightness gradually declines as the display ages. You compensate by turning brightness up even more. This accelerates the decline further. It's a downward spiral. I've measured the brightness decay on televisions that run at maximum brightness daily versus sets that run at 70%. After 3 years, the maximum brightness set is noticeably dimmer. The 70% set

20:01 looks identical to day one. That's not a small difference. That's the difference between a TV looking decent at year three and looking terrible. Here's the fix. And I know you know this already, but you've forgotten. Don't max out the brightness, period. Watch dark movies at 70% brightness. Watch football at 75%. Adjust based on the time of day and room lighting, but never, ever run daily watching at 100%. Your screen will thank you with five extra years of life. My television from 2015 still looks bright and crisp because I've never run the brightness above 70%, and I watch it every single day. You've probably heard me mention cost a few times, but here's a tool that costs $20 and prevents a $1,000 disaster. That's next. Number

20:48 six, the unprotected surge that kills instantly. If you think that tip saves money, wait until you hear the next one. Here's the part that makes repair shops shake with anger. You can prevent 90% of catastrophic television failures with a single device that costs $20, a surge protector. A power surge happens. Maybe it's lightning. Maybe it's an electrical problem in your neighborhood. Maybe it's a transformer blowing a fuse down the street. However, it happens, a voltage spike hits your electrical system. If your TV is plugged into the wall directly, that spike goes straight into the power supply. >> [music] >> The power supply dies instantly, and the television, 3 months old or 7 years old,

21:33 becomes an expensive paperweight. I had a customer in Denver last year. Lightning strike two blocks away. His TV was plugged in directly. Gone. Completely dead. The power supply exploded, and the surge damaged the main board behind it. Repair estimate, $1,400. He bought a new TV instead. That surge protector would have cost him $19. Here's what a surge protector actually does. Inside that strip of outlets, there's a device called a metal oxide varistor, or MOV. When voltage spikes above a safe level, the MOV absorbs the extra current and channels it to ground. The spike never reaches your TV. Your TV stays protected. Now, here's the conspiracy element. Manufacturers design

22:19 TVs to be vulnerable to surges. Not intentionally, but it's definitely not a priority. The cost of surge protection, $5 in the power supply, would add $5 to the retail price. Instead, they save that $5, sell you a TV for $899 instead of $904, and make money when your TV dies in a surge and you buy a new one. Here's the fix. Plug your TV into a surge protected power strip. That's it. Get a decent one with outlets for your cable box, streaming device, and anything else you connect. The whole strip costs $20. If a surge hits, the surge protector takes the damage, not your TV. You unplug it, plug it back in, and everything works. I do this on my own television setup. I do

23:06 it on every customer installation, and I've seen it prevent thousands of dollars in damage. One customer in Portland showed me his old TV that survived a lightning strike 3 years ago because it was plugged into a surge protector. The surge protector sacrificed itself. The TV is still running today. But, here's something most people don't know about their television. A static image sitting in the same spot for hours can leave a permanent ghost on your screen. That's next. Number five, the paused image trap that causes permanent ghosts. And speaking of costly mistakes, a retired couple in Helena called me last month about this exact problem. Their television was showing a permanent news logo in the corner. The logo wasn't part of the show. It was burned into the screen. The TV was only 2 years old. The

23:52 repair? The screen can't be unburned, only replacement. $2,200. Here's something OLED and premium LCD manufacturers hope you never discover. Holding a static image on the screen for too long causes what's called image retention. On OLED panels, it's even worse. It's called burn-in. It's permanent. Think about what happens when you pause a game or pause a streaming show or leave a sports broadcast paused on the scorecard. That image sits in the exact same location on the screen, pixel by pixel, hour after hour. The pixels in that area fire constantly. The pixels around it sit dormant. The active pixels age faster. The result? A permanent ghost, a faint outline of that image

24:38 that never goes away. I've seen this happen with news logos, with sports scoreboards, with game menus, with pause screens. Anything that sits static for hours on OLED or high-end LCD panels can cause it. On older LCD panels, it's rare. On OLED, it's a real risk. Here's what's happening. On OLED, each pixel is its own light source. When a pixel fires for hours continuously, it degrades faster than its neighbors. The result is that the hot pixels dim slightly over time, creating a permanent ghost of the image that was displayed. On LCD, it's similar, but less permanent. The liquid crystals in the active areas can hold a charge longer, creating image

25:23 persistence. Here's the fix. Don't pause on static images for hours. If you're stepping away, turn the TV off. If you're watching a sports game with a static scoreboard, use your TV's screen saver. Most modern TVs have screen saver options specifically to prevent this. Use them. Change what's on the screen every 30 to 40 minutes. Avoid leaving game menus, pause screens, or static content frozen on the display. This is exactly what I tell every customer who has an OLED television. It's the number one cause of premature screen failure that's completely preventable. I've seen pristine OLED screens destroyed by a pause screen left on overnight. The image lasted 2 years. The damage lasted

26:08 forever. Now, we're getting to the mounting decisions that determine whether your TV is secure or becomes a safety hazard. The next one can literally kill someone if done wrong. Number four, the weak mount that becomes a catastrophe. Here's the part that makes me genuinely angry. A mounting mistake isn't just about damaging your TV. It's about creating a flying projectile that can seriously injure someone. I've seen wall mounts fail. When they do, 75 inches of television doesn't gently fall. It crashes. A homeowner in Colorado hired a handyman, not a professional installer, to mount his 70-in television. The handyman used the wrong screw size, slightly smaller than specified, into drywall with no studs. Four months later, the TV fell

26:55 off the wall. Thankfully, no one was underneath it. The TV was destroyed. The wall was damaged, but someone could have been seriously hurt. Here's what's actually happening. Your television has specific mounting holes in the back. The mount has specific screw requirements. Usually, you need to anchor into the wall studs, the wooden frames behind the drywall. If you use the wrong screw size, it either doesn't bite into the stud or it strips the hole. The mount gradually loosens over months. Then one day, gravity wins. I've opened up fallen televisions. The mounting bracket looks fine. The television looks intact, but when I check the studs, the screws are either in drywall with no backing or they've stripped the wood completely. The mount was never secure. It was just

27:41 waiting to fall. Here's the fix. Have a professional mount your TV. This isn't a DIY area. The cost is $150 to $300. Compared to the $600 to $2,000 cost of a fallen TV and potential injury, it's insurance. If you absolutely must do it yourself, use a stud finder. Mark the studs. Use the exact screw size specified by the manufacturer. Go into the studs, not the drywall. Have someone else hold the TV while you check that the mount is rock solid before you let go. This is what I do professionally. I verify studs. I use a torque wrench to ensure screws are tight, but not over tight. And I never install a mount in drywall without a backing plate. I've seen someone's family room destroyed and a television shattered because the

28:27 mounting was wrong. It was completely preventable, but here's something equally dangerous that most people do without thinking. Covering the TV while it's running. Number three. >> [music] >> The covered TV trap that builds deadly heat. Now, there's a video on your screen right now that covers the 10 biggest appliance mistakes homeowners make. But before that, listen to this one. Covering your TV while it's on is like suffocating a person while they're trying to breathe. The consequences are severe. Ha, I've opened up televisions where someone had hung a cloth, a blanket, or decorations over or in front of the screen while watching. The internal temperature had climbed to 68° C. 68. The capacitors were swollen. The solder was starting to fracture. If that TV had run covered for much longer, it

29:14 would have caught fire. Not dramatically, just a small electrical fire inside the cabinet. Here's what's happening. Your television is designed with specific ventilation. Air comes in one way, heat exhausts another way. When you cover the TV with a sheet, with closed cabinet doors while it's running, with decorations that block the vents, you're trapping all the heat inside. The fan tries to keep up. The components temperature climbs. The power supply, which is already the hottest part of the TV, gets hotter. Capacitors dry out. Solder joints crack. Eventually, something fails catastrophically. I've replaced power supplies in televisions that were covered while running. Every single one had heat damage. Obvious, visible heat damage. Here's the fix. If

29:59 your TV is in a cabinet, leave the cabinet doors open while the TV is on. If you hang cloth nearby for decoration, keep it at least 6 in away from the screen and vents. Never drape anything over the TV while it's running. And use adequate ventilation space. 4 to 6 in behind, 2 in on the sides. This is what every television manufacturer recommends. This is what I do. And it's what repair technicians know prevents hundreds of dollars in heat damage. Now, some OLED televisions have built-in maintenance cycles that run after you turn them off. Here's why interrupting those cycles is sabotaging your TV. Number two, the unplugging mistake that stops panel protection. After two decades of servicing televisions, I've

30:45 replaced over 200 power supplies, 300 HDMI boards, and countless panels. But, the thing that makes me shake my head is how many OLED E televisions are damaged by people unplugging them during their maintenance cycles. Here's something the manual buries in fine print on page 40. Some OLED televisions run automatic pixel refresh and panel protection routines after you turn them off. These routines run for 30 minutes to an hour. They're designed to prevent burn-in. They shift pixels slightly. They run equalizing current. They keep the panel healthy. But, here's what happens. You turn off your TV, the maintenance routine starts. 5 minutes later, you unplug it because you're leaving the house, or you want to save energy, or

31:31 you just forgot. You interrupt the cycle. Now, the panel is in an unstable state. The routine didn't finish. Over weeks and months, you interrupt more cycles. The panel's protection systems never complete. Image retention appears, burn-in develops. I had a customer with an LG OLED D who was compulsively unplugging her TV after every use, trying to save electricity. Within 18 months, she had visible burn-in in the corner where her streaming menu usually sat. The TV was 3 years old. The screen would need replacement. The cost would have been $1,800. The manual said to let the TV complete its automatic cycles. She never read that part. Here's what's actually happening. OLED LED panels require

32:18 regular maintenance to stay healthy. The manufacturer builds this maintenance into firmware that runs automatically after shutdown. The cycle is designed to take 30 to 90 minutes. When you interrupt it by unplugging, you're stopping a crucial protective process mid-cycle. The panel continues degrading without the protection. Here's the fix. If you have an OLED television, let it stay plugged in and powered off for at least an hour after your last use. Or, check your manual for the specific cycle time. Let the cycles complete. Don't unplug it. Don't turn off a power strip it's connected to. Let it do its job. The power it uses is negligible. The protection is crucial. This is what OLED manufacturers recommend. This is what I tell every customer with an OLED set. And it's what

33:05 prevents expensive panel failure that most people attribute to defective manufacturing. But, we've been building up to the number one tip the entire video. The one that's the reason my 2015 television is still running perfectly today. Here it comes. Number one, the heat location mistake that ages screens years faster. You've heard me mention heat multiple times throughout this video. But, this final tip is where everything converges. And this is the mistake I see more than any other. It's mounting your television directly above a heat source. A retired couple in Spokane mounted their brand new 70-in television above their fireplace. It looked beautiful. Clean lines, perfect sight line to the whole room. Within 4 years, the TV was dim, colors had shifted, and it wouldn't power on

33:52 reliably. What I found when I opened it, heat damage throughout. The circuitry inside was literally cooked. Components that should have lasted 20 years were failing at four. Here's what's happening. A fireplace generates heat. A heater vent generates heat. Direct sunlight generates heat. Any heat source sends warm air upward. A television mounted directly above it is bathing in that rising heat constantly. Every single day that fireplace is on, the heat plume rises directly into the TV's vents. The internal temperature climbs. You're not aware of it because the front of the TV looks fine. But, inside, the power supply is baking. The the board is baking. The backlight or OLED panel is aging at triple speed. I've opened televisions that were mounted

34:38 above fireplaces. The heat damage is catastrophic. Capacitors that look new are swollen from thermal stress. Solder joints have stress fractures. Connectors have corroded from the heat accelerating oxidation. The television looks fine on the outside. Inside, it's been cremated. I've replaced over 300 power supplies in televisions mounted above heat sources. Compare that to the 50 power supplies I've replaced in televisions mounted safely away from heat. The heat is the difference between a TV lasting 5 years and lasting 20. Here's the fix. Don't mount your television above a fireplace. Don't mount it above a heater vent. Don't mount it where direct sunlight hits it during the day. Mount it on a wall that's away from heat sources. If you absolutely must mount above a fireplace, install a heat

35:25 deflector. A piece of tempered glass or metal that redirects the heat away from the TV. The deflector costs $60. The replacement panel costs $900. This is what I tell every customer. This is what every television engineer I've worked with does in their own home. And this is why my television from 2015 still looks and runs like it's 1 year old. Your TV is one of the most expensive electronics in your home. Treat it with respect. Avoid these 15 mistakes and your television will last 15, 20, even 25 years. Ignore them and manufacturers are betting you'll replace it in five. That's 15 secrets that separate televisions that die at 5 years from ones that last 20.
