Where is the vertical hold IC? Thanks.

If you can't find the vertical section, it's reasonable to assume you
can't find the dangerous EHT section either. I strongly recommend you
find someone to repair it for you.

Listen guys. I have a 2 year degree in elect/electronics. I know all about
the high voltage. I've been inside many a crt's without getting fried. I
once fixed a crt monitor by replacing a dead cap. I appreciate the concern.

New development: I realized it's as if the picture size has been increased
vertically to where the image has returned at the top but upside down. Is
there an adjustment or do I need to replace a component? Thanks.

I have a 35 year degree in experience on the job. The structure of your

That is unless you wrap it around your hand as an insulator.

I believe it's called vertical fold over. I most likely need to replace a
bad cap near the vertical hold IC.
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.

It's near the big thing with blue and yellow wires. That is on the side
of a thing that looks like a little green round thing but should be black
but if not maybe green also. Trace that thing over by the other thing and
you might see a thing that matches it. If so look to the left of that
thing and underneath another thing. Let me know how it works out for you.

The vertical amp IC is usually a SIP attached to a heatsink, around 9
pins or so.

Replace the electrolytic capacitors in the neighbourhood of this IC.
