Question about Zenith IQZ60Z97D 60 in. Rear Projection Television
The picture screen shows only 3 colored lines bowed across top no picture and a greenish bow across the bottom no menues will show . the 2 stk convergence chips were changed a few months ago and it worked fine until this latest problem I have described.. I have a service manual but it is 90% schematics and gives no help troubleshooting.
Sounds like your IC's took a dive again. Did you change them or a shop? You have to also make sure that when you change the IC's that you put plenty of heat sink compound on the back of the IC's and do not use the cheapy IC's that you can get for 20 bucks or less as I have found they do not last. This convergence board should be available as a complete board. Good Luck
