Recently capped a (horizontally mounted) 4900 that had foldover along the top. Cap kit fixed 'er right up, made the adjustments, everything looked good. But after 8 or 9 games, the screen started to develop some slight curl along the top. It also looks like it's expanding slightly, pushing things off to the right side. If the game is powered up after being off for a while, the screen looks like new again.
Sound like a simple vert. damp or B+ adjustment issue? Or something else?
