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.

Looks like 3D Picture


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.

JVC 48 in rear


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).

Convergence


Then it is likely the pre-amp transistor that controls the red is shorted out.
hopefully you have extended warranty.
there is a trick to likely get them aligned anyway if this is a tube tv.
