Question about Televison & Video

1 Answer

Vertical white line down centre of Soniq PT42SH plasma TV.

While watching TV, a white strip about an inch wide appeared down the entire length of the screen. Changing channels and powering the TV off and on did not get rid of the line. While continuing to watch the TV, i noticed a faint black line appearing from the top end on one half of the white line, gradually extending down the full length of the white line until it gradually became pitch black. it now appears as a strip that is half white and half black. Any chance it can be fixed? Is it worth fixing or better replacing?
The picture and sound is otherwise fine.

One of your "X" buffer boards is defective. In Panasonic plasma tv's they are located at the bootom of the set and connect directly to the plasma diplay panel via a thin ribbon cable. The board you want to replace will be directly in line with the discolored vertival line in the picture. The part number is on the circuit board and usualy starts with "tnp..." or "txp..."

I have a plasma tv that has two black lines about 50mm wide running vertically in the centre of the screen


Three kinds of detects count for this problem. It could be the Logic board, or the Logic Buffer board, or the PDP panel. Just drop your tv to the warranty depot shop to repair.

There is a vertical black bar along the left side of my TV. It started as a thin yellow/white bar and has grown to be about 2 or 3 inches wide, blocking that portion of the screen.


The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

White lines equally spaced 1" apart.


This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.

Vertical black line on screen


Your set has either a bad driver board or more likely a bad plasma panel.
