Samsung forum: Samsung LN46B650 Thin Black Horizontal Lines

I've had the same problem with my TV for a couple months. My lines go across the entire screen and almost look like shadows. I was told by a technician on another tech website that it is probably a power supply issue, that it's not gettting enough power. Do you think that is true? I only have (1) HDMI input from my cable box.

yesterday i was playing games i noticed the same problem that you have babes808gpa it wasnt there when i first bought the tv its only 7-8 months old and i barely use it, i did multiple test switching too my dvd, wii, and looking at picture, its still there so i looked on the forums too see if anyone have the exact same problem, my lcd tv has multiple lines are horizontal it starts from the right and fades too the left, the color is light grey, im calling samsung tomorrow, can you post if you got yours fixed or if you found out what the problem is babes808gpa thanks!

Having the tech replace an internal cable and panel today (1.28.10). I will keep you informed.

no i did not try other component connections. i use component because i'm using my "old" denon receiver with no hdmi jacks.

just wondering if replacing the "internal cable" fixed the problem?

Black lines across the whole screen. This is the Second Samsung. Needless to say I will not buy another. As I suspect the cost will be the same as purchasing a new TV.

I have a similar problem but my scan lines start left on the entire left side and begin to fade 1/2 way across the screen.
in other forums ( AV experts forums) they are saying its a bad lcd since it occurs on all sources.

I am having the same issue that all the prior customers are having. Before it was the power on/off issue which I fixed out of pocket. Then now this with the black horizontal lines. I am extremely frustrated when I paid so much money to purchase this television and then Samsung want to say its a service issue when obviously we don't all use the same service or are not the same servicer. There has to be something done because this is outrageous. What can Samsung do to better serve their customers when their customers have taken great care of their television which ultimately has taken care of the Samsung company?

I am also experiencing the thin horizontal black lines, along with an image freeze while a show continues. Has anyone tried to take Samsung to small claims court to get them to refund the purchase price of the TV or get them to replace the tv at no charge. These tv's are far to expensive $2,000+ to break within 2 to 4 years.

Personally, I am considering the small claims court route and believe I have a good shot to have Samsung stand behind their product.
