Leaking capacitors

Repair of a PCB being defective by leaking capacitors

You will see that C137 had been leaking, which was the reason of a malfunction.

After removal of the caps (careful by hand, because unsoldering was not possible),

it showed out that the other caps had been leaking too.

Found guilty and condemned to destruction.

After cleaning up the PCB with cotton bud and some alcohol.

The final result after soldering new and more reliable capacitors.
