So I just bought a used Proscan 56" projection TV (PTK195 Chassiso or CTC195). It intermittently has a strange convergence problems. The image will get bad pincushion on all 4 sides and the colors will not be lined up. The problem can be fixed by going in the Menu->Screen->Correct Image (I think)-> then selecting whatever it detected is wrong. It can also usually be fixed by turning the power off for a second. But once it starts happening it will tend to return about every 1 to 3 minutes, sometimes more sometimes less. I didn't notice this problem when I looked at it before buying, OTOH didn't have it until the second time I used it after I got it home. Any ideas what could be causing this problem?
BTW when I moved it I hauled it in my pickup lying diagonally in the back, screen up, on a bunch of foam padding. I was a bit concerned about road vibration but it was not too bad.W
