Default Zenith Sentry 2 TV

Has been addressed many times here. Do a Google groups search for
horizontal sawtooth and Zenith (possibly search by chassis or module
number). C2212 maybe? a 22uf on the 9v line to the jungle ic.

Of if it is really bright, the classic way the Zenith tubes short
internally.

A specific chassis number and year of manufacture will help a lot in
narrowing down other possibilities. Model numbers mean very little
for tv repair.

Hello, I have a Zenith Sentry 2 model sj2063s5 that I picked up for
free. I've repaired monitor's and TV's before but nothing so far with this
problem. If I leave the TV off for a day when I turn it on it shows a good
picture for about 30 seconds, then horizontal lines of distrotion distort
the picture (look like this:
---___________
---___________
---___________
there distrotions of the image being put on screen) and any graghic menus.
There is a high pitched noise from the unit, If I turn it right back on the
picture still has distrotion. I did a light hit test for joints and it
didn't affect it, I still have to go through and check joints (will do
soon). If I'm right this is a problem in the verticle circuit of this TV?
Really all I'm woundering is a direction to go and any one who may have had
a similar problem with this unit. I've not found exactly this problem on a
group search through google. Any help and information would be great and I
thank all who reply.
