Plasma TV has 3 thin black lines

Dec 28, 2010 10:18AM PST


I have a 2YO Samsung plasma, model S50HW-YB03. On the bottom section of my tv, there are three black lines running across the screen. These are three rows of pixels that are just not showing at all. This came on suddenly, and I don't know if it is an issue with the Y board, the ribbon cable, the plasma screen, or something else.

Any information on this kind of issue is appreciated. Thanks!

Plasma TV has 3 thin black lines

I'm sorry to hear that you're having this issue with your television.

Unfortunately, I have no way of diagnosing it without getting in and looking at it. I'd recommend having a service technician inspect the unit. If you'd like to have a service set up, call 800-SAMSUNG (US) and one of the customer service representatives may be able to assist.

Having the same problem. Samsung basically told me to bad
Apr 15, 2012 10:44AM PDT

I have a 50 inch Samsung Plasma that has thin black lines running horizontally all over the screen. They multiply every week it seems. I finally got to the point with Samsung after sending them pictures and my reciept, that I wrote and email to the "CEO". Basically was told that my tv was a year past its warranty and they were not going to do anything for me. I see from alot of these posts that this is not an isolated incident, in fact I have personnaly seen two other TV's with the same problem. I am thinking of going to a lawyer and starting a class action law suit as this is obviously a problem with their product and not a simple matter of wear and tear. Is there already a law suit out there for this problem?

Samsung Black Line problem
Aug 9, 2012 7:01AM PDT

I've had the same problems with my Samsung 450 Plasma with the horizontal lines appearing, granted I bought it four years ago, but this is a TV.... is this the new life span of a tv?

After calling Samsung twice, they only said, it's out of warranty and up to me to service. Ref # 510-392-0420

My response is... this is how you don't run a company... if the motor and transmission fell out of our Honda tomorrow,, I'll guarantee you that Honda would fix it and wouldn't be jerking me around about warranty issues. Because, that's their product and their name is on the front and it means something...that's how you create a brand and customer loyalty

Now, with Samsung, you've got a customer, who doesn't feel valued and guarantee will tell everyone he knows about what kind of product Samsung is...

Disappointed, wish they would do somethingSad

fixed pn58b550 plasma
May 3, 2011 10:44AM PDT

I just recently moved and when I got to the new place I had the black lines as well, a few rows all the way across horizontally. I tried searching for a fix that wasn't $680, through samsungs list of area techs, or 1300, through best buy's geek guy's. I fixed it and if I had found out how, after I paid someone else to do it, I would have shot someone*.

This is what I was thinking
Jun 30, 2011 6:08AM PDT

Thanks for that. Same situation. I moved two months ago and am now starting to have a solid vertical black bar on my pn63b590. I was pretty sure it was going to be a loose connection or heat related problem since it goes away after 20 minutes or so. Of course, heat can make connectors move and reseat themselves. I saw a video where one guy "fixes" his by beating it with a bat which kinda reinforces the loose connection thought.

Black lines turned into a entire black screen.
May 29, 2012 10:47AM PDT

I didn't get around to trying to fix the 12 or so horizontal black bars. Now my entire screen went black. Speakers still work, inputs still work (I can tell because the right sound comes through the speakers. Bur no picture for any inputs or menus. Any suggestions?

What next?
May 31, 2012 2:57AM PDT

Hi. My fears have been confirmed. The repair guy said he could fix the black screen easily, but that the horizontal black lines would still be there without replacing the panel. I will be contacting the next level regarding product complaints as this problem is way too common in a 2 year old tv. Hopefully I don't have to escalate and go the consumer protection agency route. Let me know if there is anything else I can/should do.

Thank you,

Will give this a try. Will never buy another Samsung..
Jul 20, 2012 3:50AM PDT

I will have to give this a try.

I have a PN50C450, about 2 yrs old. Recently black lines started showing up, I just moved about 5 months ago, so maybe this fix could work for me..

I do want to share with other readers my experience dealing with Samsung support though. I called the 1-800-samsung line a few times, after some useless trouble shooting routines, I was put on hold and then later cut off. Once I asked to transfer to an escalation line, (their Executive Customer Support line, which has been reference in a few other postings) It took several tries for me to get to this line as I was repeatedly getting dropped. Today I got through and am disappointed to report that it is no more help than the regular line.
I was told that the TV is 2 yrs old now and not covered under warranty (which I already knew). I then asked if Samsung was doing anything about this very common quality issue, (which is evident if you just Google Samsung plasma and black lines, and I was advised by a local repair shop to contact Samsung as the problem seems to be widespread and the cost of repair would exceed the cost of a new TV), I was told that this was purely a user's perspective that it's a quality issue... I'm totally shocked at this response, I guess Samsung must view multiple black lines as a normal feature in their TVs

After hearing that I asked if I could speak to her supervisor, to which I was told after 5 more min of holding, that no supervisor is available to talk about this issue.

The net of this is that Samsung does not care about their customers, does not feel quality and reliability is important at all, and does not seem to care if their customer never buys another Samsung.
So everyone reading this.. spread the word.

If the fix doesn't work I will have to buy a new TV, and it will NOT be a Samsung!

never buying samsung
Dec 29, 2012 4:04AM PST

Had the exact same problem, customer service and executive customer service both couldn't have cared less...very rude and no help. I asked them why I would want to buy another Samsung if they only last 2 1/2 years. Their reply was why would you?

Any updates?
Oct 16, 2012 1:51AM PDT

Just checking to see if you've heard any updates on how this repair has worked for folks. I had a 59" that a friend put a knuckle thru accidentally and can't afford to fix or replace. Killer 'cuz it was only 11 months old.

Anyway, I'm buying a used 50" that has one black line through it. If a second line shows up I'll want to give this a try. I'm a little nervous although I have been successful adding memory to my laptop and other odd jobs.

Any down side to giving this a try?

Thanks for this post. Karen

p.s. I had a 29" tube TV for over 20 years. I'm very disappointed that the industry seems to have gone the way of throw-away products...I don't know who of us can afford that!

Time for a recall or class action lawsuit against Samsung
Sep 15, 2013 10:19AM PDT

This is ridiculous....just started happening to my TV. If Samsung cant recognize this is a widespread problem only one way to get their attention. They better announce a recall soon of they may be facing yet another class action lawsuit for this issue. I'm waiting to hear from their head office advising me where to have it fixed...any mention that it is off warranty is insane when you have a consistent, widespread issue such as this.

So I followed the steps, but it didn't fix the problem. Below is a link to the photos I took while following the instructions. If I made a mistake please let me know so I can attempt to fix it. Sorry for the blurry photos, but I was doing it with one hand.

I couldn't fix mine this way either. I have the same TV. Hope there's a fix for this soon.
