JVC AV-56WP74 56 in. Rear Projection red projector is not showing images and big red line in tv

If the red line looks like a swoosh of red across the screen it may be the convergence Ic having an issue.

"Perfect Focus" problem on Samsung HCN4727W

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Suddenly, the screen shows double images on letters and numbers plus red/greenish like shadows on characters.

You don't have to replace the board, just the amps. This set uses two stk392-110 Sanyo built amps. You will also need to test and possibly replace one or more of the 1.5 ohm feed resistors in that circuit.
If you're doing this at component level try Acme in Florida for amps and resistors: 1-800-575-9833 and if you're doing this at modular level send it to PTS 1-800-844-7871
Good luck!

I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce
