[TechAssist] BUSH 2568NTX fault

Hi, I have a BUSH 2568 NTX TV which has a problem I must repair.
It has total vertical collapse (white line across centre of screen).
I have checked vertical output chip, connections etc (caps also). No visible
dry joints either.
However, when I turn the screen voltage up
slightly, I see a pincusion type fault and 1/2 of the screen is grey,(top
half is still black) with raster lines, bunching together on the right of
the TV (spaced out better on the left though)
Any ideas?
Regards
