Red Convergence on JVC AV- 65WP74

The red convergence ( horizontal ) swags downward from the middle of the screen to the right side. It is a none adjustable problem. Is this a I.C. problem or replace a complete board ? Any solution ?

    This is the second time the convergence has gone out. Last time it was almost 400.00 to get it fixed. Is this going to be a reoccuring problem?

    HELP. SHERRY

    I have the same problem going on right now. I was told it would cost between $425-$525 to get it fixed. Does anyone know of a more affordable option on replacing these items?

    Thanks,

    Dorotel

    One of my wife kids was playing video games bypassing the locked panel, (I hid the remote to avoid using the tv for games) and next day when I started the tv I noticed the double images. Tried to corrected with auto convergence and manual but the red color breaks up and the red image stays on the right of the screen.

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Cannot adjust horizontal blue convergence on WS 55857


You still have bad grounds on the ICs. Or maybe the solder has fused another pin. If not bad grounds on the ICs you have missed them elsewhere...Really concentrate and look for these bad grounds and check your caps with a cap check. And power resistors too!!!!!

Red horizonal convergence tilts instead of adjusting evenly.


For your hitachi unit one of the convergence IC is bad along with couple of low value resistance on
the convrgence board.

Good luck

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.
