Re: screen shrinks to 10 cm horizontal line

Yes, you are correct. Usually what I find in a set like that with that symptom is that the solder joints have cracked and come loose on the vertical output IC. That is the IC which drives the yoke coils that spread the picture up and down. If you have soldering experience then you can locate this IC and resolder its pins but if you have never worked on PC boards then have a qualified tech handle it for you. This is a very easy thing to repair so it should not cost too much.

Picture cut off on sides, how do i shrink picture to screen?

If model listed is correct the problem is in power supply or vertical or horizontal circuits.

If cut off on sides (horizontal) and bowed on sides it is a pincussion problem. IF short top and bottom a vertical issue--if both it is in the power supply.

Model listed is rather old and parts may not be available for it.

When the TV is first turned on, thin white lines appear horizontally across the top 4" of the screen. The lines go through the picture, distorting it. After the TV is on for a few minutes, the depth...

On this particular model there is one capacitor from the video process IC (jungle IC) that supplies the Vertical pulse that shoul be changed.
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

Pictures shrinks.. Panasonic TC-20LM Television

Shrinking picture is a voltage regulation problem in the switch mode power supply, Possibly a cap used in the feedback circuit. Or an over current condition on the B+. This is a very tech intense repair because there is no magic bullet. If it is shrinking on bright scenes then you can bet it is a regulation problem, bright scenes draw more current from the power supply causing this effect. I would not suspect the horiz output because the regulation for this circuit usually comes from the main switch mode power supply. One diagnostic is to monitor the B+ going to the horizontal output and see if it fluctuates. If so you can bet it is a cap or optical coupler in the switch mode circuit.

TV: bright line across black screen for several hours.

vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Lines on screen

Can you take a picture of the screen and post it? It is not possible for both the horizontal and vertical stages to fail at the same time to produce a cross. A picture of the screen would help significantly.
