Zenith Sentry 2 TV, weird problem with the horizontal.

[MRX37]

My latest find is a 1992 Zenith Sentry 2 19" TV. When I first found it I thought "uh oh, 90's Zenith... CRT's probably shot.

Nope, the CRT seems to be fine. The horizontal isn't right though. The picture looks scrambled.

I want to fix this TV, cos I have a feeling it was probably one of the last Zenith's made with a decent CRT...

I'll provide a model # and images later.
