Which takes me back to my original question: Where is the vertical hold
IC?
What's the shape and how many pins? Thanks.


There are two coils on the back of the CRT. The horizontal is connected to
the horizontal output transformer (which is also the high voltage
transformer, I'm sure you recognize it).

Now just track the connection to the other coil. This comes from the
vertical output stage, which is driven by the vertical sync circuit.

If your picture is stable besides of the wrong size, its probably not the
vertical IC at fault, but the power amplifier after it, or the power
supply.

If there are only a few lines, and they are crossing the picture
diagonally,
then it's the beam which is not blanked during the vertical flyback. This
can be caused by a worn out picture tube, or by the grid bias voltages. I
don't know about your TV, but usually there are some potentiometers for
adjusting the grid voltages and slightly changing it makes the lines
diasppear. That's what it lools like:

Is yours similar to that?

Thanks. Finally some useful info. The symptoms look more like when the
picture is adjusted to large and it folds back, to where you can see and
image in the lines, but upside down. Only about 1" at the top.
