Samsung LN46B650 Thin Black Horizontal Lines

by babes808gpa / January 11, 2010 7:51 AM PST

Sorry about previous post.

I'm experiencing thin black lines from the top of the screen to the bottom. It covers about a 1/3 of the entire screen. Did a Picture Test still no improvement. I played a DVD as well, I still see the lines. I viewed HD as well as Standard channels, still see the lines. Any advise?

I just responded to your other post. Sorry about that.

We know that it happens on several inputs now, but how many lines are there and where are they on the screen?

Black Horizontal Lines
by mhans14 / January 12, 2010 10:26 PM PST

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.

I had the same problem with my Samsung LED tv. I was able to fix it for no money, all on my own. It took a little bit to get the picture back but it was a very easy fix. Watch this video on YouTube. I hope this helps.

Did you have the "internal cable" replaced yet? If so, did it work?

Problem resolved!!!! Sears Tech came in and replaced the internal cable and put in a new panel. At this very moment, NO LINES! The parts used were: BN96-10075A for the Cable and BN07-00671B LCD Panel. Total fix cost was listed at $1700.00. Luckily I was covered by warranty. Took 1/2 hour to complete. Hope this helps you and speedrocks.

internal cable
by mhans14 / January 15, 2010 2:10 AM PST

If it does end up being the cable, could you see if you could get a part # of the cable from the Sears repair person? I had another tech website tell me that it was either the power supply, or it was the thick cable that runs from the power supply to the control panel. If replacing the cable works for you, I'd love to know. It would certainly be a lot cheaper to replace that cable than the power supply. I'll look forward to hearing how it goes.

46" Samsung LCD. Horizontal black lines. TV is out of warrenty. Paid $2K for the set. Paid the extra coin for the Samsung over the off brands because I didn't want to chance the TV breaking. Very upset to say the least. Samsung needs to make this right.

Have the same issue
by Chris from Kazoo / September 15, 2011 10:04 AM PDT

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.

Wow - I really had perceived (and even recommended) their products as "top of the line" in terms of quality and performance.
No more praise or purchases from me.

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.

Same Issues
by Rashaad373 / September 24, 2012 1:29 AM PDT
In reply to: As a general rule...

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?

Similar problem horizontal thin black lines spacing 1/4 inch from top to bottom. Started on Friday 05/04/2012. Tried different power out let and different inputs. no luck. Tired power recycle for 2 hours no luck. haven't switched on the unit till 05/06/2012. Switched it on again on 05/06/2012. Loosing power often. 4 to 5 times in 15 minutes. except for volume and channel button, tv is not responding for remote. Not responding to touch buttons on the front panel also. Only way to turn it off is by pulling the power cord.
I barley used the tv. out of warranty period. service center is asking around 80 for quote. Too expensive.

UN46B6000 Black Lines
by ejh1919 / November 29, 2012 9:56 AM PST

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.

AV SERVICE company diagnosed line problem as bad LCD panel
by motorcom / September 17, 2013 2:57 AM PDT

Our SAMSUNG is a LN46B610AF. I bought kit in 2009 and now it's diagnosed as having a defective LCD panel with a replacement cost of $1000 !!!

I have never ever had a TV crap out that was just 4 years old, regardless of cost.

Scouring the internet, this is a common problem and the manufacturer should be held to account.

Based on this experience, we will never, ever buy another SAMSUNG product.

by Zacharygoodrie / September 17, 2013 6:57 AM PDT

Same issue.. It's a shame that Samsung isn't compensating customers like us on a common issue like this. Especially since they are all within 4 years old. Who spends $1700+ on something that will last 2-4 years?

2009 Samsung 55 inch UNB7000 black horizontal lines
by svahldic / July 14, 2015 9:29 AM PDT

I now had the same problem creep up. This TV was $3300 when it came out, got for $2500 6-12 months later. Called a technician about problem, they said screen is going bad, $1000 to fix or just go buy a new one. Black horizontal lines show about every quarter inch on all input channels. I thought one advantage of LCDs over plasma is they would last forever. Who cares if a plasma starts to lose blackness after 10 years if LCD goes bad in 6 years or less. The internet is full of posts about Samsung LCDs with black lines now on TVs only as old as 2 years. I still have a Mitsubishi 35" TV with picture tube that is 18 years old and still working. Very disappointed in Samsung LCD life. Great review on TV when new but feel lied to about the technology. Certainly not going to trust buying Samsung phone or appliances now either regardless of review when they are new if they are only going to develop major problems down the road, and i'm definitely not buying an expensive Samsung TV ever again.

Here's the thing.
by R. Proffitt Forum moderator / July 14, 2015 9:39 AM PDT

Almost all the consumer brand TVs you see is stores are 5 year designs. Don't believe me? Just look at forums filled with this issue. finds Samsung, Sony and other makers that have this failure. Samsung's market share means you will see it more often.

Mitsubishi is no stranger to product issues. Just look at their DLP DMD issues.
