Squeeze the bezel hard and see if the stripe disappears. Probably someone “washed” the TV screen and shit ran down onto the COF.Comment

Many years ago I picked an early LED era LG with similar fault, the brighter band plus a small black stripe in the center of it with no image, it was no liquid damage, was bad joints under one COF chip, putting pressure the image recovered almost all, i tried heating it under with the big T shape iron tip but not resolved, maybe heating directly with normal cone tip can work but with my new knowledge i think is not the correct work and a better job can be made, don't ask me, i wanna try it myself before..Comment

Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!
We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre... -

Hello guys!
I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
It powers on OK and has no other issues except the following:- CAPS LOCK does not work at all
- Fn button toggles Flight Mode
- When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
- (with SHIFT pressed: 't%' and 'y^' respectively)
but when I press and hold...06-27-2025, 01:10 AM -
Hello everyone,
I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.
To assist with troubleshooting, I'm attaching two power circuit schematics:- Power
