I repaired the power socket on a 760 - which is a different style of 
connector, but the experience may be relevant.

First - check the obvious: is it the cable to the power supply which is 
internally fractured? (you probably need to test under load - at least a 
few mA in case it's a hairline).

Then - check the internal connector itself with a meter - is the power 
reliably supplied to the output pins on the connector. i.e. is the 
easily-replaceable power-socket still good?

Unfortunately, you are most likely to find that these are both OK, and 
you have a hairline fracture on the circuit board. You may be able to 
fix this - if you can locate it.

Note: make sure you are earthed, and working on an earthed surface.
