red line appearing on laptop screen

[techno0065]

i have a dell studio 1555 laptop which is 13 months old and is out of warranty.last night as i was surfing the net a red vertical line appeared on the left side of the screen and it refuses to go away.i have tried restarting and have updated display drivers but it is still there.what might be the reason for dis???kindly help.screen size is 15.6 inch with 1366*768 resolution.tried talking to the dell customer care and they said i have to extend the warranty by paying rs14000 to fix dis as the screen will have to be replaced and this is the only solution.shouls i get it done from a local laptop service shop coz ia m not ready to pay dis much.the red line is thin and is vertical.i have heard dis is common issue wid dell screens bt da customer care salesman said it does happen bt he is not willing to bargain.kindly help me sort dis out if anyone have experienced the same.
