Question about Samsung UN Televison & Video

How can I fix a 3/4 inch vertical black line on my Samsung UN60D8000?

I own a Samsung UN60D8000. About two weeks ago, my wife was cleaning the tv's screen and probably used a little too much Windex (I have special screen cleaning fluid, but she didn't know). We think that some of the windex seeped in between the bezel and the screen. After she had cleaned the tv, we had several vertical black lines on both sides of the screen. We hoped that the inside would dry out and the picture would return to normal so we left it off for 24 hours. When we turned the tv on the next day, the lines on the left side were completely gone (never came back), but the right side still has a solid black vertical line about 3/4 in thick from top to bottom. We're out of warranty, so Samsung's service contractor quoted $350. I'm a DIY guy and I'm sure I could handle this for a lot less. I just don't know where to start and haven't been able to find a teardown video for my model or similar. Ideas? Your help is very appreciated! Thanks in advance!

When liquid drips onto the x buffer boards (located along the bottom edge of the display panel ) the liquid Will damage the ribbon cables that are connected to the display panel. Replacing the display panel may be the only way to repair the tv. I've been in the tv repair business for over 30 years.... Dan

Testimonial: "Thanks for the experienced response Dan! Is it possible that replacing the ribbon cables alone could fix the lines? I removed all ribbons cables and then reconnected them in an effort to fix the issue, but it didn't change anything. Thanks again!"

    Thanks for the response! I have since taken the TV apart, but was unable to fix the black line. The TV has had the exact same line for 18 months now.

I have seen this when a person spray's directly on the tv bad move. but if you take it apart again and look very carefully you will see corrosion on the connections where two boards will connect or from board to the screen clean it very good and you might salvage the set

Hi,

Some of your lines of pixels are burning-out for some reason. If the TV is under warranty, you should have it replaced or repaired.

Rahul

I also have the same problem I phoned Samsung today to explain the tv was only 14 months old, they didn't wanna no because it was out of warrenty by 2 months. I am getting a black solid line down the left hand side of the screen. I ended up phoning Dixons were we bought it from, they have told me to get an independent engineers report done & send the report to them within 14 days. Dixon told me it was a known problem with Samsungs. They said they will fix it free of charge if they can if not they will send vouchers to the same value of the television. So beware stay clear of Samsungs.

SOURCE: Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use

On al the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black lne down the screen. Seeing as the tv is new I would get the warrantee repair on it. There is a possibility that there is a problem with the screen itself but more than likely its the boards.

SOURCE: Mitsubishi 40" TV, LT-40134 Vertical lines on left side of screen

I've got the same TV with the same problem. Sometimes by moving it on the stand the lines will go away but it only sometimes temporarily fixes the problem. For a while it seemed like it needed to heat up to go away but that is not the case. It seems like there is a bad connection somewhere but i cant seem to find it. One day, one thing will fix it, then the next day it wont do the trick. It gets very irritating.

SOURCE: Vertical black line on the screen of my 42" Magnavox flat panel lcd tv

I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.

My HL2040 printer is printing black vertical lines along the right-hand side of the page, about 3" or so. A month ago I took it apart and cleaned the roller. Still doing it.


If the lines go all the way down the page, check the position of the corona wire cleaner tab (blue or green) at the top front of the drum unit. if not parked fully to one side it will create a solid black lines where it blocks the laser. Otherwise look for some other foreign object (or torn paper piece) that may be blocking the laser from the drum. If the lines are thin and shark, check for scratches on the drum (not repairable without replacing drum). If the lines are uneven thickness but in a pattern that repeats down the page every few inches, then the film on the drum is probably worn or wearing away and the drum needs to be replaced.
