Faint horizontal lines in picture

I am having a problem with my JVC AV-27320 TV. There are faint horizontal lines in the picture. It is most obvious when the picture is dark. They are not static, but flickering across various parts of the screen. It happens regardless whether I am watching cable broadcasts, DVDs or playing video game consoles. Does anyone know what could be causing this or how to fix it?

This is usually caused by a problem in the Horizontal Output section, around the Horizontal Output transformer usually a capacitor or diode going or gone faulty... the line you see are the Horizontal "Retrace" lines that are useually "Hidden" when the circuit is OK..

Jvc hd 52g787 my position adjustment in my menu will not highlight so i can adjust picture over to the left. help please

Hello
Just make the picture status button on the remote control and get the display setting to its factory mode.

The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only)
Press the VIDEO STATUS button repetedly to get these choices.

There are faint lines at the top of the screen when the TV is on.

There are capacitors in the set's vertical output circuit that need to be replaced. TV repairs should be handled by a professional because of the hazards involved, particularly with larger sets. This is a pretty minor repair, probably under $100.

The faint white lines at the top of the screen is the warning that the pump-up capacitor in the vertical output circuit is going bad and the output itself is about to short out. When the TV stops working, the vertical output IC has finally shorted out. Replacing the vertical output IC, the pump-up capacitor and possibly a small value resistor next to the flyback (B+ for the v-out) should bring the set back to life.

Tv showing blue screen with flyback lines sound ok

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket
