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.

I have a 48" sony projection with a rainbow comming down from the top


You have convergence circuit failure. Convergence IC's have to be replaced and probably some PICO fuses that soldered on the same board. This repair require good soldering skills.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK-392-120 IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Double vision on jvc 48" rear projection television


No that is not correct
The problem you describe is a convergence issue which can be quite costly. The alignment alone is very complicated and more importantly time consuming

This convergence board problem seems to be very common and if they are not too model specific (firmware embedded) there may be service companies repairing them. I don't; haven't done a whole lot of service for years partially due to the difficulty of trying to pry stuff out of the hands (or shelves) of Asia.

My red will not converge on my philips 52" HDTV what do I do


Sounds like a convergence board problem. Cheapest fix is probably to replace the convergence board, or the tv itself.
