Question about Philips Magnavox 9P6034C 60" Rear Projection Television

Convergence & Pincushion Problem

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.

Re: Convergence & Pincushion Problem

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.

When tv is turned on the picture is distorted.thought at first that one of the bulbs was bad.took the screen off and all bulbs are lit.the red bulb looks distorted.has the bulbs got to go out to be...

Can you explain distorted in more detail?

Does the screen look 3D?  
Can you adjust the convergence for both the blue and red colors - up - down - left - right? 
If not the convergence chips and resistors are shot and should be repalced. 

If however the screen is shrinking and expanding that is a different problem.  You can get a repair kit from for this model.

60" TV has an arc in the pic

Check the fuses 1007 & 1405. If they are blown in will cause an Arc.  

Note: If the screen shrinks/expands you may need a chip kit from

If it shrinks and expands over and over it may be the opt chip. Otherwise its likely a convergence chip problem. Check to see if they have a kit for your set.

Red convergence is out of alignment

If the mis-convergence is only noticable on the left center and the top and bottom left side of the screen is good, then it sounds more like a pincushion distortion problem rather than a convergence one. Otherwise, you could have a bad pair of convergence IC's or capacitors / solder connection problems. I would doubt that adjusting the service menu would correct this problem, and you could make it much worse by trying. Better have a technican work on it if the picture quality is still good otherwise.
