Circuit board troubleshooting? (loose capacitor)?
Answer:
Yes replacement of the bad caps is needed, they should never be able to rotate, even if the outer jacket was loose it would likely indicate that cap had overheated perhaps. Simply put, order new caps and replace them.
had a marantz 2275,,,,,with 2 capacitors,tried burning tiny holes in plastic on each to put a tiny bit of lubricant on mvg part,,,,,,,did not work,think corroded capacitor oughta be replaced
Yes;
If capacitor is turning, it has lost connection to pad or through hole via. Capacitors are made with multi layers and their elctrodes are attached to each plates. It looks like that it has broken down few layers and rotating freely and that means no connection.
just resold them and the problem will be solved!!
The capacitor leads are connected to the plates inside on it. If the body of this is turning this doesn't mean that the connections are already broken. This due to the metal plate body is loosely attached to the insulators. As long as no oil coming out in this one, so this is still OK. By the way I am referring the electrolytic type capacitor.
