Samsung Plasma TV interference

[barry wilkins]

My brother in law has a large Samsung Plasma TV ,on the left hand side of the display there is a vertical band of interference ,when I was a TV engineer we used to call this "a string of pearls" ,and was caused by the tuner or IF strip picking up something from the line output stage.
Does anybody know anything about this sort of problem ?

thanks

Re: Samsung Plasma TV interference

Probably a panel failure (plasma panel failed), but would need a picture to confirm, can sometimes just be a loose connector for that part.

Thanks for the info , It cant be a failure because the picture is all there ,so perhaps it is a connection problem of some kind causing poor earthing so there is pick up of interference.

While that is possible, it is rather rare with modern displays.

Barry can you post a picture? RF interference is a problem on older CRT TV's receiving analog signals, not very common on todays digital TV's. See if your problem shows up on the digital channels or input a DVD signal. Most likely it is a failure on the plasma panel.
