Vertical Black line

I have a hyundai 42" plasma television model number: Hpt-4240. Recently i have had a 1" black vertical line appear. Although It comes and goes it is there more often than its not. Its driving me nuts!!
I have checked thats its not coming in through the scart which is where Sky, Dvd and ps2 come in.

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.
Hope ya fix it!

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

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.
