Vintage Synth Repair

Hold the circuit board to a good bright light. You may want to use a
magnifying glass and examine all the traces from the opposite side of the
board.

magnifying glass and examine all the solder joints on both sides of the
board.

Subject: [vintagesynthrepair] Finding a dry joint...!?

 

  

Hi guys,

Trying to fix a dead DX100 here. I have isolated the problem to a dry joint
or open circuit somewhere. If I slightly twist or bend the main circuit
board it all springs into life! This could take a while...;c)

Any techs here have any tips that could increase my chances of pinning down
the problem...?

Cheers,
TOM
