I have a JVC Av-32WFP1EK TV which for some time now has been suffering from horizontal barrel distortion for the past couple of years. It has now suddenly changed to horizontal pincushion.
The vertical edge is distorted by 1"-2" and can sometimes be changed by giving it a clout on the side of the case.
I've opened it up to see if there are any obvious bad joints (note how I avoided the word "dry" there) or cards not correctly inserted, but can't see anything obvious
Any ideas?
