My jvc rear projection 48" tv is showing double images, what can I do to fix this problem

In the menu do the auto convergence. If still bad replace the convergence ics. Also check resistors around the ics. You can remove the front grill and access the conv board from the front. Small board on the right. It popps out.

If it has been moved or bumped recently the sound you are hearing is the main HT lead that has been displaced. TGhis is a blasck lead with a rubber disk surround at its end that fits into the picture tube. Do not touch without turning TV Off and using rubber gloves to reinsert.

TV displays red on screen

You have two convergence amps that need to be replaced on the convergence board.This is a very common problem with these units.The part # are STK392-110 but I would upgrade to a STK392-120 or a STK392-150.Also there may be a couple of low ohm resistors that need replacing.Depending on your electronics experience this job is pretty much a straight forward soldering job that requires a certain amount of knowlege.These parts can be obtained from as a technician charge between$185.00 in shop and $250.00 inhome for this repair.It is well worth it as this particular chassis really did`nt hve very many problems, and once fixed you will have a like new picture.Good luck!!

You will need to have a service center come out to try to reset the TV using the reset jig. A JVC authorized service center will be the only ones that will have access to and training to use this jig. It is a good chance reseting it fix the color problem but it could also be something more serious.
