This is usually a phenomenon related to high power output devices being nearby. IE computer power supply, or a backup source that needs to be replaced. It can also indicate failing components inside on the main board or on the power pack of the tv. Since you say that it only works on the tv input the video board would be my first place to look.

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

Have a JVC AV-48WP30 rear projection tv set and the green seems to be out of place. the green image is lower than the others and is in a wave shape on top of screen and bottom.When I adjust the convergence...


Your convergence IC's are bad. If your not doing the work it will probably cost in the neighbor hood of $250.00 for a service company to do. Not a major repair.

I have an older big screen, and it makes this clicking sound.


Is this the actual model # AV-32F475?
If so, sounds like you have a shorted color filament within the picture tube. Could also be a video output going bad, causing intermittent shutdown when the CRT's beam current reached overload.

If lcd set the issue may be with the T con board which is responsible for video and any aberrations that you see on screen.

Cannot fix color without remote


Here's a link to order the original JVC remote controller for this model (AV-20220) from a major parts distributor if you need the remote to fix the colors on your unit:

Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...
