Resoloder vertical IC . You should get the number off the vertical chip.
Locate Vcc pin , should be about 28v. If not trace back to a diode and
check it. I would also make sure vertical IC is good or just replace it . If
you are trying to make a living off fixing TV's buy an ESR mtr and check
caps in vertical ckt also...................Charlie

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)
Thought it may be one of the video driver transistors (yoke only getting one
polarity) - in which case it might be worth my while trying to replace the
vertical output chip. It is the E-W in conjunction with 1/2 screen that is
puzzling me
Any ideas?
Regards
