Yes, I did this. I can short the two leads of the
switch but I get the
same symptoms. There's something wrong with the electronics.
When you say the 'same symptoms', what do you have to press/hold just
right for it to work?
Assuming this is an electronic problem, I would first test all the
electrolytics on an ESR meter. High-ESR capacitors cause the most odd
faults on SMPUSs...
