Can anyone help, JVC AV-48WP30 Rear Projection with a red (mostly) and a blue shadow on the picture. If I know the parts that have failed or the solution I might be able to fix at home. It happened while my son was watching, he heard a snap and the pic went to the (Bad 3D mode) red and blue shadow. Many thanks in advance for any help. TJ

Re: Red and Blue shadowing (Where are my 3d glasses)
There are two convergence IC's that are bad and need to be replaced, as this happens to almost every rear projectionj set ever made. They are stand up IC's , on a heatsink and they start with STK. They are soldered into place and this set has no user replaceable parts inside of it. If you have no solid state repair experience, you really should call out a trained tech to assist you in this repair. A TV set is no place to be diggin and experimenting inside of.

The tv 100% have a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors picture shadows or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.
You probly have a convergence cicuit failure. Replacing the convergencr IC's will probly fix it.
I recommend a professional repairman to
do it though. Particularly if it needs further adjustments after the IC's are replaced.
Probably the projection guns (my JVC had them fail on me). It started that way and eventually I had a triple image of what was on TV, one in red, one blue, one yellow, and all slightly offset from each other. The fix was new projection guns (thankfully it was under warranty as they were about $300 each).
