SOURCE: Samsung Plasma TV - picture has 6 sections of horizontal lines

All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.

How do I connect my hp laptop to my lg LCD tv? I've tried plugging in the hdmi cable to both but my tv keeps sayin ' no signal' please help meeee :(


you need to select the screen you can use because most of laptops don't support to use both screens(laptop screen & monitor / plasma tvs that have VGA port) at once.. you can select your screen by check on F function buttons on your keyboard ...you can identify that button easily because it shows two screens on it just press that button you will choose the screen you can use.

46in Vizio LCD HDTV distorted black picture when tv is turned on


Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

47" plasma 1080p ... screen went black , sound


Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.

Tv flat screen only half the screen works rest is black


This is casued by the buffer boards on the right or left edge of the plasma tv. You need a direct replacement for the top buffer and then your picture will return!
