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....10-23-2025, 04:33 AM -
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 -
Hello all!
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....
