Question about Panasonic CT-20G14 20" TV

TV Screen problem

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

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.

SOURCE: Horizontal white lines across top of TV screen

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.

How do I make the picture bigger so it fills the screen and not have black bands at top and bottom


Banding of the screen usually means that the aspect ratio of the broadcast is different than the screen size ratio. Most modern TVs are 16:9 ratio. Most modern TV broadcasts and movies are as well. In those cases, when in HD mode, you will see the picture fill the entire screen. Older broadcasts and many syndicated reruns are in the old 4:3 format and will be banded. Also, some movies are in larger formats than 16:9 and will reduce in size in order to get the entire picture on the screen. That being said, most TVs DO have a stretch and.or zoom feature that will expand all images to full screen size. Be advised that this can result is image distortion, especially of the 4:3 ration broadcasts. Others will have some of the picture cut off and you may see some items such as network logos, etc. partially chopped off in this mode.

Disney princess tv suddenly narrowed the visible part of the screen. Now everything is squished into a two in wide band with all the rest of the screen is black.


if that 2 band according to you from top to bottom,it has a defective vertical stage.if this two band appears one on top and one at the bottom,it`s on vertical stage.leaky capacitors,resistance changed or resistor devalued ang ic`s, are too weak to amplify a signal to make the screen complete....

The screen has colored vertical lines and becomes to a dark black band about 6 inches of width.The tv is exactly two years old by today.


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.

XBR 4 vertical black band, ghosting/smearing, getting worse.


Hi, I have a similar issue which is progressively getting worse. My TV is on a sliding mount, and interestingly enough, sometimes I can "jilt" it by hitting it and it clears. This seems to me to be a connector problem, where heat (thermal expansions, electrical resistances) can introduce degrading signal. Now if I could find a manual on how to take this damn thing apart.......Certainly does't solve the warranty issue, but at least gives a reason for one to kick their TV.

Wide black area top of the screen.


More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

You probably have a component breaking down on one of the circuit boards. It would have to be checked out to find out which one. Stargazer
