Look for damaged components such as blown capacitors (they leak and have popped top), voltage regulators and diodes which can all be tested with a multimeter. Check also for yellowish spots on the backside to see components which my have overheated and lastly verify for broken traces and contacts that might have been unsoldered.
I have recovered over 3 boards in the past only by replacing capacitors and soldering wires to broken traces.
Good Luck
