Hi new to all this so please be gentle. I have a samsung ps51d6900 that I have owned for approx 16 months. The problem is that the screen has a distinct line horizontally right in the middle. it appears lighter on the top half than the bottom, this is only visible when It's showing a dark scene, normal bright scenes the picture is perfect. Also when It's switched on it displays white sparkles all over the screen for a few seconds, when I call up the menu the blue menu screen shows black sparkles. Any help would be grateful if this could be an easy fix.

Re: Samsung ps51d6900
Hi Tom I tried to take a picture but it won't show up on the photo. The line runs across the screen horizontal exactly in the middle, It's like the screen is in two halves, the line I assume is only there because the bottom of the screen is black and the top is dark gray. This shows up when there is no picture on the screen or on dark scenes. when you you go close to the screen the bottom is black and the top shows gray speckles. I have a blu ray player that outputs 60hz and when I am watching a film on it it seems to be less noticable than the sky hd box which is 50hz.Comment

Re: Samsung ps51d6900
Looking closely at the screen, does it appear that the bottom half only has every second line lit up?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung ps51d6900
Hi Tom thanks for taking the time to help. in answer to your question the bottom of the screen looks OK. when you go close to the screen the top half has what looks like tiny grey speckles which you can see very clearly, the bottom also has the grey speckles but not so pronounced. so what I think is happening is when I go back to my 12 ft viewing distance you can still see the grey speckles on the top half of the screen. if you view a dark scene in a film say a dark wall the top half is lighter than the bottom. I have read on various forums that one of the buffer boards could be going bad.Comment

Re: Samsung ps51d6900
There is only one buffer board in this set, but it's possible part of it is going bad, so I'd suggest that as a first possible fault.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung ps51d6900
An update to the problem I am having, last night I was watching a film on netflix through my sony blu ray player, to see the line on the screen you have to look very hard, It's almost not there. When I press the info button on the tv it says 1920x1080@60hz unlike the sky hd box which is 1920x1080@50hz and the line on the screen is very noticeable. I have been reading about dithering on plasma screens, didn't know what it was. when I go up close to my screen I can see it, but on the top half of the screen It's worse. So when I go back to my 12ft seating position I can still see it on the top half of the screen but not the bottom. Don't know if this info can help to diagnose the problemComment

Re: Samsung ps51d6900
It's very hard to tell without seeing a picture or video, but I would be thinking buffer or control board fault.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Samsung ps51d6900
Hi Tom thanks again for your input. You say this tv has one buffer board, I have been having a look on EBay for parts and have come across two items for my model, an xb buffer board and and a Yb buffer board, which one or both.Comment

Re: Samsung ps51d6900
Hello roncam29..
Did you manage to repair your TV by replacing the YB buffer Board ?
My TV has started with the same issue.. e.g. top half brighter on dark scenes.
It appears from left to right..
I have read on some other forums that people have replaced the whole panel to resolve this issue ? not sure if this is because they can't be bothered repairing or its just not repairable due to Plasma Dirty Screen Effect ? DSE ?Comment

Re: Samsung ps51d6900
Purchase a YB board from eBay for around £20..
Once fitted to the TV the picture brightness from the top half was improved
considerably to the point where I don't notice it on dark scenes anymore.
Going up close to the TV you can still see the line very slightly, but as you don't watch TV this close, its not really an issue.
Replacing this YB Board was fairly easy if you take your time, and don't rush.Comment

Re: Samsung ps51d6900
Hello, I have the same problem just mine is vertical line.
When power on the tv will stay on for like 10 second and turn off and on again.
I have done a Power Up Sequence Diagnose and you could see will work without the main,and still see the lines. Any help would be great.
Please see photos.Attached FilesComment

Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM -
Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
Please help. Thanks in advance! -
HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
