First thing: Let us know exactly what you have in your setup e.g. Anything connected? Electron PCB version? and anything else that would help identifying what you have - maybe a photo of the insides.
If you have just a stand-alone Electron that has the ULA in a socket (issue 2 or 4 PCBs ?) then the starting point would be to remove the ULA* and carefully clean the contacts of both the ULA and socket.
* See here . . . for useful guides!
If that doesn't fix the issue then remove the power supply board (3 screws) and check the power input socket - check for cracks around the soldered joint - re-solder if needed.
While you have the Electron 'open' - remove the main PCB (4 screws) inspect all the soldered joints.
If the above is a little daunting (?) let us know . . . .
