I would probably take my meter and check how many ohms are reading on either side of some of the power rail capacitors. You might have a short that is pulling something to ground. For instance, you mention that touching your finger across some of the pin tends to start things back up. That could be because some corrosion is keeping the "reset" pin pulled to ground (or pulled high depending on the chip.) It could also be that something has gone higher resistance, such as a resitor on a voltage sense circuit/divider.

But yes, I would check on either side of some of the capacitors on those power rails and just see if anything shows up with a lower resistance..
