This is a long shot, but you might try this:
After taking my 7300 apart a few times, I ended up with a system 
that only worked with the cover off and failed with it closed.  
It finally turned out that several of the solder joints had
failed where the connector to the ribbon cable is soldered to the power
supply.  After resoldering, everything worked fine.

If you are going to trash the supply anyway, it wouldn't hurt to re-solder
everything.  Your problem sounds like a mechanical interconnection
problem.
