I am guessing that a trace or via got damaged during soldering or removal. Take a close look with a good magnifier or video microscope.
The most important troubleshooting tool is your eyes.

Sounds like capacitors that have developed high ESR on the low voltage P.S.U.
Have you a meter to measure ESR? Their almost as good as a working Huntron!

The "good" was repaired. It was a 1k resistor I don't remember wich one but I think it was a reference voltage or something
