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... -
Eventually discovered a burn mark near lower corner of LCD. Here is a summary- Backlight on, no image
- Disconnect right buffer board (view from front), left side display comes on
- Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
- Buffer board is pretty simple

I have an AOC U27G3X 4K gaming monitor that I use both as a TV and for gaming on a Nintendo Switch 2 console. Recently, something very strange has been happening to it. After playing a game that has an on-screen timer for a few minutes, the last digit of the timer (the one rapidly flickering from 0 to 9) appears to burn in on the monitor. Going to a different source or power cycling the monitor does not help; there is a constant flickering area on the screen where that digit was.
It seems strange that only that digit would burn in, and NOT the other digits that are changing less frequently.... -
Hi,
I have just replaced led set of this vestel tv due to age.
I would like to reduce backlight from service mode. I have tried menu 4725 but in the menu i can't change anything.
Any help pls? I don't want to change from electronics inverter feedback resistor ideally.
Thanks again.... -
Hello. Have this Dell G15 5511 la-k455p that new gpu fan burn and left pwm sig from sio with 10 ohms.
I read that this sio MEC1515 must be programmed, but someone says dont. My Vertyanov seems dont have this model in it.
Laptop works and can be tricked by split pwm, but i dont want to do this stuff this way.
So anyone really knows if it must be programmed?09-16-2025, 07:11 AM
