I have a pincushion problem with my Sony 500ps monitor. I had a power
surge and when I rebooted I have pronounced pincushion and can only correct
it by adjusting to "0" in the adjustments, and I still have some
distortion. When I attempt to play a game it reverts to a lesser
resolution and the error magnifies. This happened once before and a few
weeks later the problem corrected itself so I have hopes however unfounded
that it is correctable. Other than the obvious suggestion to buy a UPS for
the future, does anyone have a suggestion as to what the problem might be?
I found on reference to bad "caps" but I am not very bright and don't have
a clue what that means.

Thanks for any help
