Hello.
Try to use a magnifying glass and a strong light to check the circuit board and the soldering joints of the components.
Using a multimeter, check if the power supply is distributed thru the board.
You can find the schematics on the following link:

Good luck!
Best regards.

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
