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.

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.

TV comes on but after a while there becomes a hourglass shape on screen. It is drawn in 1/2 inch on the sides. Can this be fixed cheap?

yes. has a pincushion circuit problem. since tv works and then starts to bow, its a bad solder connection. when tv warms up the metal expands and looses connection. when cold, the solder constricts and unit works fine. just solder deflection area. you can probably tap on board and locally find area to solder.

Have you ever had this problem?

Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.

Could you please confirm the model number so I can look up the probable part?

Thanks,
Dan

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 www.repairkits.com

If it shrinks and expands over and over it may be the opt chip. Otherwise its likely a convergence chip problem. Check www.magnavoxhelp.com 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.
