Another dump find.
The screen resolution is 2560 X 1440, so it would be nice to get this working. I read it uses the same panel an an iMac.
The LED backlight driver board has a blown capacitor, however before it went, it looks like it got very hot. PC board traces are burnt, and even into the board surface.
I tried cleaning some of the burnt stuff, and replaced all the capacitors. I also added that jumper to an area that looked like the board copper was toasted. No luck
I'm not sure how many layers the PC board has, so I'm thinking it's too far gone. I tried looking for a replacement, but haven't been able to find one. I did a general search for the board. Also looked on eBay, Amazon and Shopjimmy. The part number on the back is HQ-LED28-1B.
Does anyone have any other places I could find this?
Thanks,
Paul
