    Most probably it is the TCON board which has gone bad.

Tip

TV shows either: black screen with: white vertical or, horizontal line


If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, find the too hot transistor or, chip; using component coolant; spray the too hot component with the component cooler until the screen comes back to normal. To fix: apply white coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

Call 1-800-Samsung to set up a warranty service call. They will repair it in your home if they send a Samsung Field Engineer. You probably have a bad Main bd.

Vertical white line down centre of Soniq PT42SH plasma TV.


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..."

Samsung HP-R4252, white vertical line


Unfortunately you probably have a bad lcd panel. This is caused by the heat of the panel releasing the solder that holds the ribbon cable that supplies the picture information to the panel. A lcd panel is more often than not, more expensive than getting a new tv, also the new tv will come with a warranty. Most of the unit I have had this problem with were uneconomical to repair. Sorry for the bad news, Hope this helps.
