Purchased this 56" projection TV

You can get it repaired. Its maybe a resistor/s thats losing its value and needs to be replaced.
You can locate this on the mother board close to the or near to the Fly-back transformer section.
Good luck.

JVC 56 inch projection AV-56WP74 red color not aligned

I have the same tv set and about 4months ago Ihad the IC STK392-110 replaced. I was told that it was the most common problem with proj. tvs. It did solve the probem until last night when I went into the menu to change a audio setting and stupiditely accesed the convergence setting and decided to do an auto adjustment which mesed up my beutiful HD picture. Now I have the red out of alignment ad even after I did a reset and multiple manual adjustmets it is still off at the top and bottom af my screen.

Red spot on HDTV

This is a LCD projection TV and will need to have the light engine replaced. Hopefully you have a warranty on it or it is still covered by Panasonic.
