My TV shows compressed picture in middle strip area,while some times it shows full screen may be if kept on for long time.Sometimes it's picture jump to and fro from middle srip to full screen. Any help pls,what is remote control code for this model?
Repair the vertical ic output circuit. May be solder connections, may be failing capacitors. What do you mean by remote control code? All Zenith's from that era use pretty much the same remote control information, just some remotes are missing buttons.
Above model was manufactured in U.S.I tried all JENSEN Zenith TV listed remote control codes,but none of them working.
Sounds like you either need to find another Zenith tv to try the remote on, or try a different remote control.
I tried to restore full vertical picture by turning a small white plastic knob,but picture shortened to middle strip after closing body and at every restart.
I noticed when I pushed a metal mounting/upstand ,picture became vertical.I am looking to put a micro shim underside to get full picture permanently. Sometimes I tried to make full vertical coverage of screen by turning knob of R2112. Any other suggestions pls.
Here is some other cross info: Chassis C10, Service Maual (CM-146/C-10(A), Part Number 923-3218
Why not just find and repair the bad solder connections that are causing the problem?
My eyes can't find bad solder in vicinity of these,I need a microscope and must know where is weak joint and how to touch up it. Tell me how I recognize it as a weak joint,I mean what are symbols/symptoms.I don't have simple soldering tools,if I know sure this that is to be soldered than I may purchase simple solder tools.
People without 'simple soldering tools' shouldn't be poking around in televisions.
'Nuff said.

Why not find and repair the bad solder connection? The problem is going to get worse as time goes on.

I have purchased PEMCON soldering kit from Wall Mart,now I need to know which part# to be touched up?
Part numbers ? Look over the whole circuit board and touch up any suspect areas. I didn't read your first post but it sounds like you should concentrate on the vertical deflection area. If you don't know where to look for this area on the circuit board then please don't open your TV.
