    Every 15-20 seconds the TV turns off ( picture goes black, sound goes off) for 3-4 seconds then it comes back on.

The ribbon is usually the problem but it's to hard to soler back so just take it to a repair shop and pay 350 to have the board replaced. it's a common problem. just got ours back...good as new.

Could be a loose ribbon cable on a buffer board, or one of the buffer could be going bad

SOURCE: black vertical line on p42w34p plasma

Two large black lines is a different problem
thin black wavey type line that comes
and goes sometimes reaches the bottom
of the screen sometimes has white
streak at bottom is parisitc interference
stray signal not returning to ground
can be caused by cracked solder
joint somewhere loose cable connection
ground loop Basically it is an ac signal
that is not returning to ground because of
a marginal filter capacitor or any ground
return path. some power plug can be
reversed to solve when the plug is reversed
and the ground side of the plug is actually
connected to earth ground Best way to
trace it is with a good scope where you
can see the noise signal on the pulse
waveform

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.

Black vertical line on p42w34p plasma

The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.

1" black vertical line in center of screen. Sony Plasma.

NOT DEFECTIVE!!!
There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable2_bing.gifnear the black lines. Unplug the ribbon cable and look for black chipson the underside of it, I think they say 100 on them, you need toresolder both ends on each chip. Should fix the black line issue.
