Hello everyone.
I have a challenging power board that I am trying to sort out. I could bin this thing but I'm stubborn.
The problem was hazy display. Horizontal lines.
So I opened it up and there was significant signs of overheating on two parts of the board. See the attached pic.
The rest of the monitor seems to be fine. No signs of damage.
One of the caps in the corner was obviously blown. The rest appeared to be ok. But I replaced them anyway.
I also replaced a couple of diodes on the board.
Didn't fix the problem.
There is an integrated circuit on the board that also shows signs of overheating. You can see that in the pic.
There is no identification on this IC. It appears to have been covered up or deliberately removed.
(Maybe it's top secret. There are a couple of these boards on ebay and the ICs all look like that)
U901. It has 11 pins. Does anyone know what this IC is? Or what it might be. A suggestion?
Tall order I know but this is the first PC monitor I have opened up. I am wondering if there's a one size fits all IC.
Any thoughts at all?
Thanks
