My Panasonic T.V. started yesterday with a 2 inch line across the screen where I could see colors and the rest of the screen was black. A few minutes later it changed to a wobbly picture with a lot of wavy lines across the entire picture. It may work fine after that or go back to the 2 inch line across the screen. What is the problem?
Re: Color line across the center of a black screen
I had the same problem. My TV has 2 to 3 color lines jumping up and down. But as soon as I strike on the body, the picture resume again. I take an electronic technician and soldered all joints with soldering gun, now it is OK. So the problem is the breakage of lead joints and you can confirm by striking the body with hand to change the color lines to picture.

Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.
The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .
If the lines are slightly diagonal and in red, blue and green you have a problem in the ABL circuit. if the lines are only one color you may take the front grill cover offf and remove the panel. look fro the black box 2 inches square with 6 little controls on it. 3 are for focue 3 are for screen the middle on of the screen is the green adjustment the other 2 should be labled r and b respectivly. what ever the color of the line turn the control labeled screen and r b or g for that color ever so ligtly counter clock wise.
The line of color is due to a failure in the vertical circuit. The main suspects are the vertical Ic AN15525A and/or capacitor c308 [email protected] If you have the capacity to do so, you should check the other electrolytic capacitors in the vertical circuit which are USUALLY located near the vertical IC in most cases you can purchase the part at https://www.encompassparts.com/webwiz/wwiz.asp?wwizmstr=WEB.SEE&partnumber=5760279&smodel=CT32SL15N or mcm electronics
