Does your Samsung plasma suffer from horizontal line bleed? - Page 6

post #151 of 245
I just bought a LG PX950 set and noticed this line bleeding as well. Fairly signifigant, it's my first plasma and I don't really know how bad it is. The set looks great other then this, and I guess I will live with it. There's a bunch of people int eh LG PX950 owners thread talking about it

Oh, i just posted a seperate message without a response and this pops up.

I guess its a known issue. It didn't start on day 1. It just started recently on my PN58C7000

I didn't really find many answers what samsung did to fix. Have they been replacing these units?

I have this problem on my Panny plasma as well. Seems worse with lower resolution content. It's surprising.

Hi there.
I have a Samsung 58" 2010 plasma 58C590, and this is a common issue, but I have not seen it on programming like this.
I usually see it on lettering against a light background, where the background has a darker streak to the edge corresponding to the black lettering, say on a commercial with a light background with bold lettering.
I have heard about this on all plasma displays, some more than others.
I am not sure of the technical details, but it is common, dare I say, "normal".
All displays have flaws, I suppose, as nothing is perfect.
Enjoy.
Mike

slight horizontal line bleeds visible on my samsung pn50c550 ( samsung plasma does not offer uniformly white/light colors?? ); during the white to light pink slides on the break in dvd
post #159 of 245
was wondering if this occurs on lg50pk250/550 as well ?

"Line bleed" occurs on all plasmas, can be considered part of the tech.
post #161 of 245
does this occur on lcd displays too ?

No, it is an issue with uneven power distribution across a plasma panel. A flaw that would probably cost too much for plasma manufacturers to address.

From what I've read here it seems like some people are mistaking something else for line bleed.

If you are seeing lines on solid light color fills.... then you have some other issue that is not line bleeding. Line bleeding should only happen during material where there is light/dark horizontal lines on the screen in a background that appear to "trail" through people or objects which would be in front of said background.

I can't see how line bleed would occur on a completely white screen, or any light color fill. That, to me, sounds like something else.... perhaps a poorly applied AR filter or something.

FWIW, I have 3 Kuro's.... 2 141FD's and a 500M. I can see line bleed evey so faintly on extremely limited program material, so even the best of the best can suffer from it. Although I will say that it's 100% negligible on my Kuro's and absolutely nowhere near as bad as any pic I've seen pasted here or in an LG thread.

To be honest I've only ever seen line bleed once on my Kuro's... while playing Final Fantasy 13 when you first load a save... the splash/loading screen that scrolls the text giving you a description of the area you're in. That's the only time I've ever witnessed it, and it didn't bother me at all.

My brand new 50c450 suffers from horizontal line bleed and significant banding. Stinks. Is anyone's set better?

Isn't this normal with plasmas? My VT25 (Panasonic) has it in exactly the same way. I hope it's normal.

I wish i had taken pictures.

TV1: Samsung PN50C550G1F, One line near the very center and another about 5-6in higher. The repair guy that came out called Samsung's Nerds while he was here and they had a discussion about how the lines were cause by any one of the layers of glass being slightly warped causing the lines. Samsung was kind enough to talk to Best Buy and get me in store credit for me to buy a new tv.

TV2: Samsung PN50C490B3D, Same thing noticed it on day 1. One line about 5-6in from the top, and two dead pixels in bottom left quarter of tv. Returned it to best buy and got...

TV3: Samsung PN50C680G5F, One line near the center another a few inches above that one. Took it back

TV4: Samsung PN50C680G5F, Same as the last but this one looks fine. Im going to keep an eye out for the lines, and if they appear before the 30day return period im going to take it back.

A Best Buy Tv sales rep told me that Samsung televisions have a 10% return rate. Thats not to say that all the tvs have lines, they just have a high return rate. My buying experience has been poor.

On a brighter note, I am now a wall mount pro!

I don't notice this issue on my 54in G10. I also don't look for it from 2 feet away either.

It is obvious under the right conditions, for example the "blooper" real at the end of Toy Story 2 as the credits role. All plasmas do this so this thread is like asking "Do you breathe oxygen?".

Hi folks, I almost never post here but I found something interesting and thought it might help some others the same way others have helped me over the years here.

I was just watching The Sunset Limited on HBO (great movie but certainly not for everyone. That's neither here nor there, but if you have HBO it will make a good test case). Anyhoo the end credits of the movie feature black text on an all white(ish) background (it actually slightly messes with color levels so it's not true white), and I saw the extreme white banding bleed that some others have described above. I'd seen it occasionally on some commercials and could never figure out how to "fix" it, but it really annoyed me this time and I started searching again, leading me here.

I've got a Sammy 50C680. I went through every setting - I've turned all dynamic contrast/"film mode"/etc settings off because I prefer a more natural picture, and toggling these back on did nothing. However I found that turning all "White Balance" settings to 0 (from the default 25) almost completely eliminated the problem. It's still very slightly there but almost unnoticeable now. This makes everything far darker, but bumping the Brightness and/or Cell Light settings up restored the brightness while removing that horrible banding. It looks great now!

I'm not sure if this will help too many of you, but try it out if you have a similar model or setting. Good luck!

Hi Folks,

I purchased an LG PK550 in early December and started noticing/researching the horizontal line bleeding problem in January. The line bleed was ALWAYS on my tv I just didn't notice it right away since I wasn't aware of it nor was I looking for it. I DID notice it though and wondered WTF to myself before actually researching or hearing of the issue. My first HDTV (before this current LG Plasma), was just a generic 720p plasma and that TV did NOT have any line bleeding. The IR was pretty bad but that was my only issue with the old TV.

Anyways we are now in mid-April and I am just now getting my TV looked at/serviced. I have the 4 year product service plan through Future Shop but since the TV is in it's first year I had to contact LG. They sent out a technician from a local repair shop who handles repairs for LG and other manufacturers. At first the guy tried replacing the power supply, then the mainboard...both to no avail. This was yesterday, and he took my TV to the shop and gave me a loaner LCD to use in the meantime. He or his superior had both apparently never experienced this line bleeding issue...which is quite surprising as many plasmas have this problem just by doing a simple Google search.

I just have a feeling that the repair center is gonna say either tough luck or it doesn't seem that bad, and not do anything to help me out. The line bleed IS very evident, but again you have to be watching certain programs (like The Office, Wrestling/Boxing) to be distracted by it. However, now that I know it's there, I can notice it in almost everything I watch if I look for it. The menus on the TV as well as PS3/Xbox 360 make it very evident, as does the green preview screen with the white text when watching previews on Blu-ray.

If the repair shop doesn't help me, obviously my next step is to call LG. I have read this entire thread and a few others and there doesn't seem to be any acknowledgment of this problem by the manufacturers OR any solution. I knew when buying plasma I had to deal with Image Retention & Glare, but the benefit of smooth motion, more accurate color reproduction, true Blacks with no light leakage & price vs the LCD far outweighed any of those negatives.

I have attached some pics for reference.

MIne had this in two spots on the top third of the screen. I have a 50C550 and Samsung had a tech come out who swapped both the panel and the power supply. When he powered it back up the bleed was in the same spots and he said it was not normal. Samsung is replacing my unit with a 51D550.

Why did you resurect a thread about SAMSUNGS dealing with an issue that if you had read the forums is there an ALL PLASMAS more or less?

You don't even have a Samsung TV.

PS, if you'd read the threads on your tv you would have gotten your answer too.

First - I most certainly do own a Samsung Plasma Television (a 50C550 to be exact). It is being picked up and replaced by Samsung with a 51D550 which is this years model of the 550 Series.

Second - The technician that serviced my C550 replaced the Panel and the Powersupply and the Horzontial line bleed was in the exact same spots on the panel. This is why Samsung is replacing my unit, because the fix would have been replacement of most of the ribbon cables, and the motherboard and the cost of this repair was more that just giving me a new unit.

Third - I stopped over at Best Buy today, and the C550's all showed horizontal line bleed on the scrolling bars screen, but none of the 2011 D550's showed any at all.
post #175 of 245
Happy to report that after some serious time with the 51d550 that it does not suffer from any form of line bleed. No lines at all. If you currently have a Samsung plasma that is still under warranty from Samsung, they are actively replacing units from 2010 to 2011 models if the problem cannot be repaired cost effectively by the local tech they send.

Wow. This Post has been very helpful. I'm having the same issue. So far, two main boards (first one fried and actually left a black burn mark on the inside if the panel, second one was bad hdmi connectors). However, that's somewhat unrelated. Due to this issue, I've had the entire panel replaced recently and I'm still seeing the purple horizontal line bleed. Thus tv so far has been the most unreliable TV I have ever owned. In essence the only original part on the TV is the power supply...and it's still having issues. I've only had this TV for about 7 months. My last plasma (42" Panasonic) was ging strong for over 5 years without issue and is still going. I love the TV's firm factor and picture when its not having the horizontal line bleed. I'm calling them again and going to try and get a 2011 (if I can).

Just an update. Samsung is replacing the set with a 2011 model - the PN59D7000 (which is actually an inch bigger than my current model). I guess with ALL the issues I've had, they figured at this point it's easier to just replace it. This goes to show...be persistent. We paid for a top end product and it should perform as such. I will say their support is top notch.
post #178 of 245
Having the same issue with my pn63c8000.. Did you just tell them you wanted a replacement? I don't want to waste my time or theres trying to repair it. I could pull the card saying this is a known problem on the forums and most are not able to be repaired so a replacement is necessary.

Let me know what your best route was.

Thanks!
post #179 of 245
I am having the exact same issues with my PN58C680. I've had a level 2 tech came out to look at my TV and he adjusted all the picture settings and pulled the back off of the TV to adjust the voltages, none of which did anything to the bleed. He seemed to think that Samsung would try to replace the panel, because he didn't think changing the main or logic boards would accomplish anything since the bleeding occurred on the service menu in addition to normal viewing.

He then took pictures and videos of the bleeding, he said that they were having to send them to Samsung and that I should hear back from them within a week, it has now been two weeks.

So, I called the service center yesterday and was told that I would be called back within 30 minutes with information about what Samsung is going to do, but I got no call. Today I called 1800SAMSUNG and was told that my service order number was canceled and the tech put in the notes that the TV was 'ok'.

I just bought a PS3 today and was playing Assassin's Creed and the bleeding on the load screens is just horrible, it almost seems like the problem is getting worse. I originally only noticed it during commercials and cartoons, but now I am seeing it in normal TV and movies.

What should I do from here? I've got a friend who has a 2008 Samsung 50" plasma and a friend who has a Panasonic 50" G10 and neither of those sets have this kind of bleeding.

Any advice would be helpful. Thanks.

If you have it there, then you will see it in "normal" program material!

In fact, the "green screen" is a very good tool to test TVs in regards of linebleeding.

The LG PZ950 has no linebleeding. The PV350 has mild linebleeding but the old PK550 has a lot of linebleeding, so bad, it hurts the eyes.
