Question about Televison & Video
A vertical line appeared on the right-hand side of my Sansui 47'' LCD TV. I took it in to the store and they sent it for repairs. When it came back the line was still there, only less prominent.
How do I go about fixing this?

Usualy a problem with the LCD screen itself, that takes replacing the whole screen to fix. Sorry. Could also be an internal connector that has gone bad. There are tiny transistors on most displays that control whole rows and columns. It sounds like one went bad, causing a dead, or constant on, column. Unless you are REALLY handy, it will probably need to go to a service center for repair, which could be very expensive. Try flexing your screen - wrap a non-fibrous cloth around your hand and squeeze the screen lightly all around the edge. If you find a point where squeezing the screen makes things better or worse, explore that point further. Squeeze just hard enough to make a white area go light grey or yellow. It's safe to squeeze gently with something fluffy when the computer is turned-on. Could be a cable problem - either the cable is not making a good connection at one end, or the cable itself may have been crushed and one of the lines in it broken. Replacing the cable is far cheaper than replacing the display. Good luck

Need to check the two things.
1st -- need to exchange T-con Board.
2nd -- need to exchange the cables between T-con & LCD panel or
between T-con & Main(LVDS cable)

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.
Three reasons why one vertical line accross screen can happen in LCD;
1.The missing signal from the controller IC to
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.
Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel
Place the rubber on the top of TCP
Gently close back the top casing
