Question about Panasonic CT-25G6 25" TV

1 Answer

The TV turns on and you can hear the sound but the picture is dark except for a thin line of blue dots in the center of the screen.

Part of the time the TV works fine, and other times it does not. When you turn the TV on in some cases it turns on and you can watch it for 45 minutes to an hour and then the picture starts to flip back and forth between a normal picture to just a dark screen with only a thin blue line of dots in the center of the screen. If you tap the side of the TV the screeen may come back only to fade out in another ten minutes or so. If you turn the TV off and then turn it back on once it is warm, you only get the dark screen with the thin blue lines. The TV is only 5 years old. Any idea what this might be and what parts would be needed to fix it?

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck

I turned my television on then it made the tv frame made a noise!and now the screen is black except for this thin line across the middle of the screen which is display the picture

Most likely the vertical oscillator circuit has failed. As CRT televisions have gone the way of the dinosaur, my advice to you is to give a fond adieu and invest in a new TV.

I am trying to help my neighbor. She has a Sanyo flat screen tv Model DS20930. The picture she gets is a thin line across the center of the screen.

Set the brightness, contrast and colour control of that TV to minimum. Watch it in a dark room whether ther are thin white lines across the screen, at about an inch apart, from bottom to top of the screen. If there are lines, that TV needs screen control adjustments. That is, now the screen voltage given to the picture tube went high to some reasons. If you have confidence that you can adjust it, I will guide you.
Open the back cover of that TV. Locate the LOT [Line output Transformer], usually one red thick wire is connected to the top of the picture tube with the help of a rubber ****** and clip. In most TVs it can be located and can be seen as the back cover opened. There are two variable control, fitted, integrated to LOT. Normally the upper one is marked as focus, and the lower one is marked as screen. You shoud adjust this control to avoid these lines.
It is a live service, that is the TV must be switched on during this time, and take causion in every respect not hurt by yoursef and the TV. Keep the children away from you, and an other adult person beside you is better. A liitle turn counterclockwise will remove this problem.

Thin horizonal line in middle on dark screen

The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.

Blue tint and lines on screen.

Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
