from my archived emails:
I had a CTC203 that clicked 5 times but wouldn't turn on. The fix was a bad
solder joint on the PIP module. Was a surface mount resistor.
Al Marquardt
Look at all the surface mount caps to ground on that line for leakage or
glue holding cap in place. Just start removing caps is the best way I know.
