HP 8" Digital Picture Frame model df810v1. Screen initially lights up with images but after a few minutes, the screen goes completely black. Would this likely be a capacitor problem? I've posted a picture of the board. If this is likely a capacitor problem, can those bad capacitors be identified for me on this picture? Thanks. None of the capacitors appear to be bulging.

Re: HP Digital Picture Frame goes black
What is the part number of IC chip that has a heat sink tab to the board and also has a lot of pins on it and looks like some thing spilled on it or burned up it hard to tell which one it is
It is on left hand side of the board toward the bottom of the board
Can you take a closer photo of that chip thanksLast edited by sam_sam_sam; 05-01-2017, 01:40 PM.9 PC LCD Monitor

Re: HP Digital Picture Frame goes black
Looks like there is also that conductive glue on the high voltage transformer, lower left corner of the photo in the first post. Burn mark on right side of it, likely causing the display to shut down.
I have had to deal with that cr!p in HP evil (EVO) mini toaster (SFF desktop) power supply that shorted out from that glue. The supply had the glue poured all over the board. It took me 2 hours to scrape it off the board. Unfortunately, I know of no other way to remove except to carefully scrape.Stupidity should be a crime, especially for drivers. I have NO patience for them.

Re: HP Digital Picture Frame goes black
Look at the pads on the transformer the soldiering joint on the left hand side dose not look very good and another one a few pins from that one dose not look
Good either I would resoldier all the pins on the transformer
If you have an ( ex-o-knife or very thin blade screw driver)I would try to remove more of the glue but be very care not to dig deep in to the board9 PC LCD Monitor
