Question about Philips Magnavox 9P6034C 60" Rear Projection Television
Manufactured in 1999. Screen started shrinking to small area then expanding to full screen while cold. After heating up, problem went away. I sprayed several IC with cold spray and narrowed problem to hotside controller, an optocupoler and a could other IC (don't remember what they were). During cold spray I got pincushion problem and convergance issue. Looks like pincushion is causing guns not to align. I replaced the suspect IC. The flickering stopped, but the pincushion and convergance is still bad. I suspect bad ICs blew out something else. I really would like schematic, but having trouble finding one.
I had a similiar problem. My screen would shrink in then expand. After a few months of doing this it just broke altogether. No sound or video. Its not fixed.
You can get a repair kit from this site.
