Re: LCD Burn In
It is not burn in. Unfortunately Polaroid used very poor quality CHUNGWHA, CHI-MEI or sometimes AUO LCD screens in these TVs which have mura build up over years. The problem is unrepairable, though reducing the brightness and loosening the case screws can sometimes reduce the effect.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection... -

Westinghouse TV WD48FAB100 Not Powering On – Burn Mark Found on Power Supply .
I have a Westinghouse LED TV, model WD48FAB100 that is not powering on. Upon removing the back cover, I noticed a burn mark where the AC cord connects to the power supply/main board. In this model, there is only one board combining the two functions. Previous owner said the TV experienced a lightening strike, but who knows. I checked the main fuse, tested OK. Here are a collection of readings from the power supply ports. Looking for some guidance on what to test/check next.... -
I have a Sony 75x940e that I just fixed with the help of the forum (bad emmc). For the last couple of months I was noticing some burn in of the android home icons on dark backgrounds (photo is attached). I always thought VA panels were immune to burn ins. Is there anything I can do to fix it? Could it be because of a failing component other than the panel itself?...07-19-2023, 09:23 PM -
I have a Dell E5470 that powers up and boots windows no problem. Using a non-standard universal type charger, it shuts down immediately if moved, (power short in that charger or AC power jack) because the battery has no charge and isn't charging orange/white lights blinking on the front. When first powered up, BIOS power alarm stated that it could not detect the voltage setting and I had to dis-able the message to get past this. It got into Windows fine, as long as not moved, so I dis-assembled it looking for a cold solder joint on the power jack that I thought might be lifting off the MB, but... -
Hello!
I'm a few days old into this TV screens repair universe so please bear with me.
Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.
- I did the classic unplug and hold power button to discharge the caps but it didn't help.
- I did a factory reset as well...
