This actually worked! It seems like the EASY fixes never work for me, but the second option on this video actually worked perfectly. The right half of my 65 inch Vizio was darker. I figured a 30 second fix is at least worth a try. Still can't believe it worked! Thank you!!!!
Anyone with this issue, as I had, I found a fix that he vaguely covered I believe. So I had the top half super dim and figured it was time to chunk it and spend another $500 on a new one but wait, I fixed it!! I tried the unplugging, pressing the power button for 30 seconds, etc but that didn’t work. So I thought I would try this: menu, Reset & Admin, Reboot TV. Bam. Works like a charm now. Would’ve never thought that it would be such an easy fix. Thank you!
Update: worked once but the top half darkness returned the next night and the fix did not help this time. Not sure why it worked the first time but not the second. Will look into it more.
Thanks for this because this very thing happened to me earlier today for the very first time as I was watching tv. I tried the soft recycle three times to no avail and since my tv is only 15 months old and I LUCKILY bought the extra 3 year warranty, I filed a claim with Allstate. But then I came back and re-watched your video because I had passed over the part about unplugging, depressing the power button and repluging in and I did that and the darkness was all gone! Just as clear and bright as it was before! So thanks a lot!! I wonder what it is about that process that made it straighten up.
Wow! I just did the second method that you push the button for 30 sec and it worked fine. Now my monitor is as before. Very helpfull tips. Thanx a lot ♥️
Firstly, thanks for the video ( soft reset fixed my issue. ) Second, if soft resetting fixed the issue, does that mean there is still something to worry about? Like what would be the underlying issue that caused the problem in the first place?
Great call on that one, amazing how the soft reset fixed your issue:) To be honest only time will tell if there is an underlying issue, you should be good to go from now on but with TV's these days they just don't make them like they used to:( Have a great weekend:)
Thank you very much. Tried the unplug and power button method. This worked with my locally made TV, saved me money and a trip to a technician. God bless from the Philippines.
I agree my friend:) I was super scared transporting it back home, I thought I cracked it driving on the freeway. I ordered the LED lights from China but they won't be here until March:(
Did the LED backlight strip replacement actually fix this television, or was it something else, like the power supply board? I looked for the follow up video that was mentioned and could not find it.
To follow up on my own comment... I went with the LED backlight replacement first, since it was only 55 USD for the strips. It did fix the issue with the top being darker than the bottom. I'm pretty sure it would fix most dark/bright screen issues after having the TV apart and seeing how the boards and LED strips all connect to each other.
A lot of the times it's the LED and they're super easy to fix. Just be patient and put all the layers back together slowly. My first attempt I rushed and destroyed the layers. All the junk tvs on CL have been gold for me since.
Woke up this morning to my PS4 having the same issue, dark on top light on the bottom. The soft reset trick worked for me, hope it works for you guys as well.
Were you ultimately able to fix this problem? I have a Vizio D55-F2 with the exact same issue. I repaired several dead backlight LEDs and tested all strips before putting it back together to no avail. Going to check the drive signals next. This set has LED strips divided into five left-side and five right-side which makes it kind of odd to lose just the upper half backlighting. Thanks.
@@GrumpySphynx. This what I posted to iFixit a couple of years ago and still working fine: I have a Vizio D55-F2 with a darkened top half that appears exactly like the picture in the original posting. I disassembled the panel and replaced all defective LEDs, some of which fail open causing an entire strip to go out while others fail shorted allowing other LEDs in the strip to continue working. I tested all the strips before reassembling only to find the problem remained. I then began looking at the signals from the backlight PWM controller and saw that the darkened top strips were actually being PWM’d while the bottom half was full on. By luck, I disconnected the bottom strip’s 58V supply as a test and all other strips came on and, even at 50% duty cycle, it appeared to have a nearly uniform brightness. The darkened state also appears to stem from a possible power up test because the bottom LED row did not light when reconnecting the 58V supply while powered on and it appeared to be no PWM signal for that row as if it had been disabled. The 58V supply is from a very noisy switching circuit and I wonder if the fact that the mosfet for the bottom row is located right beside it could be affecting possibly the current sense going back to the backlight IC. It could also just be the backlight IC is bad, but it is a Novatek NT50511S for which I cannot find a data sheet. For now, I’ll live with it since the missing bottom row is hardly noticeable.
Heh, I have a similar issue just before the Super Bowl. I think I'll be going with the throw Vizio away option and get a decent brand this time around.
the soft power cycle and factory reset didn't work. bought this $700 70 inch vizio v705-H3 in christmas 2021 and got this darker zone in 2024. i'll be buying the LED driver board for $30-$70 and try to fix it. this is not an LED strip issue they won't dim they will simply not turn on if it's the strips. it's one of your boards
Yes because they used good full sized parts. But of course, they also weighed 100lbs and took up about 20% of room space lol. Nowadays, in order to get those stunning pictures and slim profiles, they have to use microchips and itty bitty SMD components. They're much more prone to dying out from anything, but especially temperature issues. So it's all a trade off.
Hey Chris, I got this TV. My problem is that the picture starts out fine, then after about 20 minutes I notice a dark area starts to appear. What may be the problem? If it was less it would be dark right from the start, but thats not the case. Thanks!
I have a Vizio D43-D1 and this my exact problem. I do not have the tools and the TV was purchased in 2016 from Walmart. Is it worth repairing? What will it cost to repair?
would backlights from a broken lcd tv work for replacement to a tv that has a dimmed screen and lcd is fine? or are the blacklights all different makes and models nd i need to open it first to see what model and make it is first?
My Vizio D55-F2 is doing something weird... When I first turn it on, if it's on a TV channel, the screen will be full bright for about a half-a-second, maybe one full second. Then it goes dim in spots. And the same spots every time, as if some of the LEDs are burned out. But those LEDs work for a half-a-second or so -- and every single time, too. When you first turn it on after it sits overnight, or when you turn it off and back on after watching it for hours. So clearly those LEDs at those spots are capable of working. It's almost as if they're being de-activated by the TV (as if, say, the local-dimming circuit has gone a bit nuts). I fear that buying new LEDs won't fix my problem, since these LEDs do work, 100%, for about half a second or so... Consistently... Any tips?
Thanks for the advice i turned the tv off and held down the power button for 30 seconds half of my tv was darker than the other side but once i turned it off and held the power button down for 30 seconds it went back to normal i have a flat screen haier tv i think its in between 47 to 55 inches its pretty big but its old as hell i had this tv for about 9 to 10 years its really old but still works really good lol
It Hass to do with the overlay. When you first turn the TV on, there's a message that overlays on the top of the TV and dims part of the TV for some reason it gets stuck and doesn't re-Brighten. I believe it's a software issue.
My led backlights started going out until eventually the screen went black. Fixed my pos Vizio with a used $15 t-con board from eBay. Now I’m returning my new 85” Samsung 😢
My tv only has backlights at the bottom, and the new ones I bought do not want to power the whole screen, when it was the only one for this model number of the TV
it didnt work for me, maybe because during holding the power button i accidentally let go and then started again lmao, but i went to settingsand my backlight was set to 50 so put it at 100 and it upped the top but its still noticeable, but even at default 50 its not that bad, so i kept it at 50 because of that reason and because i dont wanna burn out the backlights, ill try the reset thing again and hopefully it works. but if it doesnt its alright, because this tv is pretty old.
Hi Chris, on my 2018 P65-F1 the whole screen is dark similar to your upper half and I'm still able to see the images. Is there any way to check if all my LEDs are the problem or maybe the LEDs driver is the problem?
Found a thing that says factory reset, but I am afraid to do that because it might erase all of my input names and who knows what else. As far as taking the back off, etc, lol no way am I doing that.
No way! I found a vizio e601ia3 at the dump sitting out and the picture is the SAME and the TV is edge lit so I'm. Gonna order them lol weird tho wish I could post a picture to show u lol
Hey I have the same problem and replaced thr leds and still have the problem. Power board has been replaced and soon the t con board. Did new back Leds work for you?
Does Somebody have a solution of that the screen is normal than a black haze comes over the tv and restart it self pls somebody its a Samsung oled tv 55 inch
Great video Scott. Didnt work for me as I have a slightly different problem. When i first turn my tv on. The top half flashes from left to right. From normal brightness level to very dark. If i go to picture settings, More picture settings, then Clear Action. Turning Clear action OFF then ON again fixes the issue untill the tv is turned off. But once turned on I have to repeat the process. Sooo Annoying. Any idea about why it just started doing this or how to permanently fix this bug? Thanks
Every 50 inch Vizio tv I have bought and used for gaming gets a dark spot that spreads over the tv screen. I am pretty sure it from it starting to burn out. Both TVs were 2-3 years old. I won't be buying this brand again and I do not recommend it for gaming regardless of the lower than average price for the tv. Vizio is pretty much trash and you are wasting your money if you buy one for gaming
I have the problem where it was lighter on top and darker on bottom. I tried the first thing you said but didn’t have the soft reset button. So I then found a button on the back that I THOUGHT was the power button and held it in. It shut off then came back on by itself. The picture did get lighter but still not normal
