Yes, one of your convergence IC's have gone bad. They are located on the convergence board inside the tv and there are two of them. They are inexpensive and easy to replace if you know how to solder. Watch out for the JVC booby trap sensor on the dvi input card. Don't run the tv with the back panel off unless you have disconnected the DVI card from the main board. I would even cover the little sensor with black electrical tape. Then it is safe to work on the tv when it's open and on. Well safe for those who know what they are doing.
