Question about Panasonic CT-20G14 20" TV
Hello, My TV is about 5 years old and a few days ago the screen started to reduce size; wide black bands appearing at the top and bottom, and the picture becoming narrow across the center. When we called the Panasonic 1800 number and talked to trouble shooting over the phone they had us reset the TV. Upon doing so, the TV shows that it has a code TN-4. How can we fix this? How much will it cost? Is it worth fixing, or would we be better off investing in a new TV? Thanks
suspect it's 1 or a couple of bad capacitors in the vertical deflection circuit the caps are in the 400 series, c400,c401,c402, etc... check or replace c414,c418 & c417

test your remote first by placeing in front of a cell phone camera and press any button on the remote and look for a blinking light on the cell phones lcd screen (same as taking a picture) if you the blinking light then your infrared remote sensor is bad inside the tv. part cost about 10 dollars.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.
