Jeff, did you change the Vertical IC? also check R570(4.7 ohm) and R540 (56K sm). Willie. Hunter TV Detroit,Mich.

Replaced D615(33v), Q605, Q606(Shorted) R566, high in value, D629 (1N4148..shorted) and I replaced the opto..all diodes and transistors shorted again. I replaced again, this time replacing Q604..33v zener shorted again. I checked D621, D609, D616, 617, 613, the 10 ohm resistor R654. Evidently I'm missing something..and losing on a job that should have been a quick fix.. Can anyone offer any help? Thanks.
