Can you get a pic of the back side? I bet the 3 solder joints on the voltage regulator chip have overheated and "de-soldered" themselves. Check the diodes with an ohm meter. You should have continuity in one direction, and none in the other if they're good. Those transistors could possibly "de-solder" themselves also.

I'm an electronics tech by trade, and I'm only going on the pic. I've never personally had one of these apart (yet). VR's are notorious for de-soldering themselves. You can actually get a clip-on heat sink for them. Diode failure is easy to check for. What's the number on that IC chip?
