Hi guys. I just picked up a P220f with what looks like the same
vertical deflection problem. I'm about to check the 4n35 optoisolator
to see if that is faulty.
Also about to check the ICB02. basically i'm going to do voltage
measurements and compare them to the data sheet. Any suggestions on a
better way or anything special to look for?

I have already checked ZDB01 and it looks ok.. it should be a 36v
Zener?

any suggestions or help would be really appreciated.

Thanks
