Question about Samsung Televison & Video

Open Question

I have a Samsung Plasma #PN50A550S1FXZA that has vertical lines (think Logic Board) and it will not accept a signal from Comcast/Xfinity (think Main Board). Am I on the right track?

SOURCE: Black Vertical Lines in screen

All I can tell you is that you maybe have left your T.V. on a channel that didn't move for so long, or maybe someone else did and it burnt the screen. Plasma's run off of plasma gas to create the great picture and they collect on the screen and stick. What you need to do is go to your menu and look for "screen burn protection" and put it on white and let it sit for 20 minutes. All of one color such as white doesn't harm your T.V. The only way anything burns is like a bright white line in front of a black background.

Every single time you replace a sustain boardyou must replace both sustain boards because those boards works together.

SOURCE: 42 inch samsung plasma tv black vertical lines

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

SOURCE: plasma 42" daewoo edtv black line down middle

Attempting the solder fix is a big undertaking, gaining access to the components is a MAJOR undertaking, and probably not worth your while.
If it is simply one line you might try the baseball Bat fix....
In reference to the "basebal Bat fix" it works on occasion by using percussive force to realign the ribbon cables.
DO NOT use a baseball bat, but use a rubber mallet and with the power off tap gently directly above and below the offending line.
Its worth doing this if yo cannot live with the line.
If you can live with it, leave well enough alone!

Plasma. Why does picture have vertical bar distortion?


Hopefully, it is just the video signal cable. Make sure it is firmly connected or try another cable. If that doesn't work, you will have to have the TV checked by a professional.

There are at least two issues here. First you have bad buffer boards. Second Very possibly a bad X-Main bd and P-Logic bds. Have a trained Samsung tech troubleshoot the set.
