You have bad convergence ic's. You can take the convergence board out yourself and take the part to a repair man to have him replace the ic's. I've had it done twice on my tv, it cost about 200 bucks.

Picture Bowed towards the center


It is a convergence problem, probably one of the convergence ICs has blown and must be replaced. Call the number in the last pages of your user manual to get repair service in your area.

Colours split and vertical bowed green line at to and bottom of s


This is a convergence problem that can be either poor solder connections at the convergence ICs or defective ICs. If you can solder and feel comfortable working inside the set where there are potentially dangerous high voltages, update this and further details and instructions will be provided.

Thanks,

With the bow in it it's likely the convergence has failed... Where did you purchase the amps that you put in it? Did you use a good heat sink grease to mount them?? Did you really scrutinize the resistors in the feed and return circuits???

Three colours don't converge


Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider

Red convergence is bad.


Hi, you need to change the convergence ICs , STKs: and some resistors,low values; , after changing them, you will have to go into the service mode, to do some adjustments.that's it.
