    Left and right side of picture shrinks about one inch towards center, this is horizontal not vertical.



    Thanks anyway,

You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

    OK. I read that wrong. I'll look up the schematic tonight and try to get you a few more options.

Panasonic ct-20g11u on channel plays sound but no picture any ideas are welcome


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Panasonic TV picture shrinks to a line


There is an IC which controls the vertical deflection and over the course of a few (or 8) years with the set heating up and cooling off some of the connections work their way loose causing the symptoms you describe.
If you were to bang on the side of the set you could likely "pop" it back in but this is not a good solution. The vertical IC needs to be re-soldered. This is especially common in Panasonic sets. About 10 minutes with a soldering iron should have it worked out.

If you're handy with a soldering iron I can tell you what to look for.

Sides of the picture are encroaching and making watching bothersome. Can this be adjusted by the consumer in some way?


this is most likely a problem with a capacitor going back in the horizontal stage of the tv's circuit. if the tv has a horizontal knob on the front somwhere you may be able to expand the width of the picture for while but eventually the problem will continue in which case if you know someone who knows how to replace electronic components the bad capacitor(s) will need to be replaced or the tv will have to be replaced.

Panasonic CT-32G6E Intermittent single horizontal line


I would suggest to locate a part that looks like the one on this link and re solder all the pins, also check for any high power resistor nearby the IC295890 and put some fresh solder.
Let me know if you need further assistance.

In older CRT televisions the horizontal power supply can start to degrade causing the picture to shrink.
Take it to a qualified repair man to have him replace the particular components that are starting to die. This repair will require identifying the particular component and replacing it. 
Often times just finding the bad component can take hours of troubleshooting by a skilled technician.
Tho, before you take it in try ruling out one simple issue like bad mains voltage. Try plugging it into a different outlet in a different part of the house.

Help with panasonic ct-z1410


If the picture is short top to bottom then the vertical is your problem . Check the caps in this area as they tend to become weak can't fill the verticals height . The transistor you talk about if it reads 1 ohm from the collector to the base or the emitter then the set would not work , But it will read 1ohm from the base to the emitter . Check the vertical . Good luck

Buzzing sound, no picture on my Panasonic TV


You might have a short causing the set not to start. Probably in the horizontal/high voltage circuit. The buzzing sound that you're hearing is the power supply overloaded. Stargazer
