The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,PioneerRED GHOSTING - tried convergence - 2_bing.gif Hitachi,Mitsubishi,Zenith and others.

Ghosting or a 3D image. A yellow and blue ghosting or shadowing image. Looks much like the top picture in the "picture ghosting image" entry. Is this a convergence problem?


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Misaligned Convergence


Is anenvolved job to repair a convergence problem,the way to go about it is to locate the convergence amplifier IC's,one for each color(red green,blue)check for loose conections at the ic's legs,after resoldering all the legs see if an improvement is present if it gets better you will be able to adjust from the custumer controls,but if no improvement the Ic's will have to be replaced.Some units have a separete board were you can adjust convergence after replacing the Ic's and other units you have to access the service menu to be able to do the adjustments but just doing this adjustments can be very challeging even for a train technician,I would suggest you seek assistance from a servicer and get an estimate.
