Question about Pioneer SD-P50A3-K TV
This is a convergence problem that is not likely to be caused by anyone hitting the TV. Since striking the set appeared to "fix" it, it suggests that the problem is a connection one rather than a failure of an electronic part. If you can solder, you should be able to repair this yourself. First try resolcdering the pins on the convergence ICs. These are large black ICs attached to a heatsink. They should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs with new ones.
