Faint horizontal lines in picture

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.

disgaussing will not help this problem..i am scared your picture tube problem or try to change the crt socket first it is not cost much

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.

try cleaning your heads

the sound is locked off the TV good picture

you may just need to get rid of it and get a new lcd tv with the new tuner.

A bright Horizontal Line indicates failure of teh Vertical deflection Circuits.
Get a competent Technician to have a look.

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.

There is most likely the main power supply has several shorted parts in it, depending on how old it is, it might be worth at least an estimate. if you have homeowners insurance, you may want to concider reporting this to them. Good Luck

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
