Philips brilliance bdm4350uc. Turns on ok each time for a few seconds then the light goes dark. This is an LED monitor, so no inverter right? (Most posts about similar issues I found said it was a bad inverter.) I saw that for LED, it could be the driver, and that it's often on the power board. I bought a replacement power board, but the issue remained. The replacement turned out to be used, which I didn't expect, but I wouldn't expect it to have the exact same problem, so I'm rather thinking the problem is elsewhere.

I'm not sure where to look next. There's another large board, but I don't really know if it makes sense to suspect it. It's appreciate some tips. There's nothing visibly suspect like bulging caps. See pictures below. The power board in the pics is the replacement one.

Edit: Additional info: I can (barely) see some of the image after the display light turns off, when shining a bright light on it. There's also some darker spots on the full blue Philips splash screen when it first turns on, so it does seem to indicate LED failure.
