Hello again,
I'm in possession of another problematic 19" PhotoVu Digital Picture Frame, but this one is a 2007 PV1965 (Generation Two). I'm still pretty much a newb with electronics, but feel a bit more confident after successfully repairing the first one (thanks to all your help).

CURRENT SYMPTOMS:
Before this frame finally completely died, it exhibited the following symptoms for a few days prior … would boot-up but the LCD would only display the default photos stored within the frame's software. Just before the default photos displayed, there was bright green horizontal lines across the screen for about 15 seconds. None of the three USB 2.0 ports would recognize a USB flash drive with stored photos. Sometimes, disconnecting the power cord and re-connecting it, would enable one of the USB flash drives to load, but this became less and less frequent until they no longer worked at all. When the frame worked properly, inserting the flash drive with photos would automatically switch from displaying the default photos and load/display those on the flash drive. Also, there is a small push-button switch on the exterior of the enclosure that gives access to an on-screen, 10-option menu for things like powering the frame down, turning the display off, restart, reset to factory defaults, software update, etc). This switch no longer works either.
When I opened up the frame, I noticed that the 12V power adapter connected to the main computer board was humming/clicking and the LED light was blinking. Everything with the video board and inverter looked fine as did the 12V power adapter dedicated to them. I replaced the faulty power adapter with a matching, but higher quality Power Stream power adapter. At that point, the frame booted up again but exhibited the same symptoms that I described above.
I did notice that one of the capacitors downstream of where the power is connected to the main board was domed and also seemed raised up a bit off the board. Upon closer inspection it looked like something was pushing out from the bottom of that capacitor too. All the capacitors on this board are Nichicon.
The domed capacitor is a 1500uf, 10V, 105º. There is another matching one right beside it and a few 1000uf, 10V, 105º capacitors close by. There looks to a (here's the newb talking) a switching mosfet ? right next to the domed capacitor.
At this point, I know I will have to replace some capacitors and was wondering how many and which ones I should start with. Any replacements will be definitely be Panasonic (FR, FM or FC, in that order). I replaced ten or so capacitors on the previous repair, but that was a video board, not the main board. Should I just send the board into badcaps for repair?
Close-up photo of underside of main board is the area when the "domed" capacitor sits. I will gladly take additional photos as needed/requested.
Thanks in advance for any help you can provide. Take care!
