If still under warranty or if you have no electronic repair experience
you should take the set back to the shop or to a repair person. Some of
the solutions described below can be dangerous, TV's are very hazardous
to service. Even when plugged out, TV's can store very high voltages.
Check the blue horizontal convergence amp on the convergence panel. Whether or not this is an in house solution, is up to your experience in electronic repair and specifically TVs.
You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.
hi. this will be an easy fix for you if you are a good solder. you will need to replace the convergence chip that is located on the PC board(main). this chip is damaged and it has failed due to this damage that has occurred. click below for your new convergence chip(stk).
I have the same problem and now there is convergence problem with the entire screen, double images and ghosting ...i was told that some IC's are burned our ...etc..i'm waiting to see if they sell the entire board since the TV's are 10 years old... will let U know what i get as a response.
