JVC AV_48WP30 Screen loses color, everything is in like negative color

I had the convergience issue a few months ago and had that fixed, now I have an issue where the screen just goes into negative color. For a while the screen would go like this for a few mins. and then come back normal...but now I can't get it to come back. I have tried to reset but there is not change. Any ideas? Thanks.

Sounds like shading, caused by convergence IC or bad solder connections in convergence circuit. Check the CONVERGENCE GALLERY for shading.

JVC design is generally reliable. It is extremely unlikely that you would have 2 unrelated failures.

The convergience is off(screen is different colors) &I don,t have the remote that goes with it (broken). Where can I get the remote for the tv because a universal wouldn't work?


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

JVC AV-48WP30 problem starting up


The old video card has seen better days, methinks. All those symptoms lead one to conclude it needs a 'substitute' to enter the field, or call a long TV time out(too much pro and super bowl isms, eh?)..

Are you planning on doing this yourself?

JVC AV-48WP30 48 in. Rear... Problem


Your convergence I.C's ( integrated circuits ) Have failed. Replace Both I.C's with Stk392-150's. The unit is equipped with 110's. These are large IC's pn the convergence board located near the front of the unit. You need soldering/desoldering experience to do this job. I would recommend seeking professional assistance.
