Well after spending most of a day, pondering the schematic, changing a
few caps and a lot of thinking and probing, it seemed that I could make
it verticle jitter by probing the pieces parts of the set, but not with
100% certainty. Then sliding each yoke back a little and rotating,
hoping to find or eliminate any yoke leakage possibility. I called it
a day and was to get a few additional caps monday.

Well I moved a tv from other room as a temporary substitute for the
duration of the repair. I hooked the sub up in place of the Mitzi and
that is when I discovered the actual source of the problem....

The cable box!!!

Have had a number of cable box problems over the years but haven't seen
an intermittent vertical jitter before. I guess that after only 50
years of circuit shooting I still haven't seen it all..As Gilda used to
say..."Its always something"

One looses the "hand" if you don't do this every day.

Many thanks for the inputs guys.

I remember you, this is JURB. I was forced to change my handle by ISP,
incredibly stooopid people at aol.

Fancy this one, sold a guy a monitor projector. A Panasonic cieling
mounted unit. Has a VCR or something as a tuner, but gets a humbar on
all sources whenever the cable is hooked up. I mean even the DVD had
the bar when the cable was hooked up. This guy among other things is an
electrician. Luckily that helped him understand the solution. Of course
we weren't going to tell him to cut the ground prong off the projector,
what we did was made him an antenna isolator. Just took one for a cheap
set, the ones without an isolated power supply and attached an F
connector so it would connect.

See the cable ground was in a different location than the power earth,
apparently there is a voltage gradient between those two points.

Of course I was the guy who had to adjust the vertical height to fix a
greyscale problem too. That's another story. Of course I also know all
too well that if you have no high voltage it might be a speaker. Both
of these gems were Sonys.

If you think that's interesting you should see the ones I gave up on.

PS You ain't the only old one, I'm 45 and my boss is 58, last week I
dug into the bottom of my toolbox and got out the old Magnavox tool.
Remeber those ? The old 4 way.My spanner is broken off though. It was
still pretty cool.

If your client is an electrician and he is in the US he should know that
code requires the cable line to be grounded to the power service groundfor
several years now.
