I have 4 25" polo chassis here with various issues. I have a feeling this is gonna be a time consuming project... but fun and worth while.
One of the chassis keeps blowing HOTs from the base to emiter. I have recapped and replaced the flyback. Replaced IC102, IC103, IC104, T107
I have narrowed the problem down to the deflection side of the board by lifting L109 with a 60w lightbulb as a load.
I am trying to track down the culprit and have tested every component i can think of. I think something is failing under load. Im leaning towards the polypropylene capacitors.
They test fine out of circuit. Is there any other way i can test these to verify that the are 'good' ?
