    Ours seems to go away when the humidity is high in the house such as when we are washing and drying clothes.

If this is intermittent, it could be a loose connection on one of the flex cable that connects the digital control board to the screen that is located under the audio/video assemblies.

I HAVE THREE BLACK LINES AND A YELLOW VERTICAL LINE DOWN THE CENTRE OF MY SAMSUNG 50" PLASMA TV. ONLY 10 MONTHS OLD! WHAT CAN I DO?


The TV should be still under warranty. Most of the flat panel TVs come with a one year warranty from the manufacture. I wouldn't mess with the to void the warranty.
The problem most likely is the buffer/scan boards on the bottom connected to the screen. It controls the vertical image on the screen. The other possibility is the plasma display panel is bad.
Go the warranty route first. This may get expensive to fix.

Have LG 42 inch plasma, 1 inch black line down center of screen, picture good other than black line blocking center of screen, comes and goes sometimes


Sounds like the middle scalar board is defective. Since the issue comes and goes it could just be a loose connection to the between the scalar board and the PDP Module (plasma panel).

Great caution needs to be taken when checking this connection because it is a ribbon cable connection it and needs to be put in correctly aligned or it could cause a short in one of the circuit boards.

Black line in centr of Screen


sounds like a bad panel, try reseating any cables you can on the buffers . the buffers would be on the lower edge right where the black line appears. unfortunately Vizio does not supply panels.

Black lines on plasma


The matrix controler or the matrix drive area is failing. The fix is to change the proper circuit boards, and then do the factory setup to match the board is necessary. In the worse case, it may be the display screen itself that has a failure occuring.

You will have to bring the set for factory service to have the work done. If the set is out of warranty, it may be expensive to service.

Black line down the center of screen


Usually this means pixel, but I would question if the line is mostly near right side or left side of screen? If more to one side this could be a bad board inside. for more info ctechnicians.com

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works
