You can sort of make out that the rest (bottom) of the picture is upside

down. After it's been on for a while, the bottom half starts to extend

further down, and becomes right side up, but is still squashed, so a 1/4

of the screen remains blank. Other than the brightness and V-hold, there

are no other adjustments inside or outside.



Does anyone have any ideas where to look for the reason for this? I have an

electrical background (not with TVs though), so replacing parts would not be

a problem. Any hints would be appreciated. -Rick

You almost certainly have a dried out capacitor in the vertical deflection amplifier. Just a guess but I bet it's 1000 to 2200 uF very near the vertical amp. This happens all the time with Sony CRT monitors.
