I have this Samsung QLED tv that works but has a vertical stripe. I know its most likely the cof chip but curious if anyone has successfully repaired one?

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... -
Good day Experts
