It can be T-CON board or worst case the LCD panel itself. You can try reseating the ribbon cables between the T-CON board and the LCD panel first to see if it fix the problem.

Vertical red and green lines on the screen
Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hoping this will help in solving the problem....

Well the capacitor problem usually causes power up problems. If your tv comes on now it sounds like you dont have the same problem.Vertical lines are usually caused by bad flat panel or dirty ribbon cable contacts on flat panel connections.

Colorful vertical lines on screen
more likely to be bad LCD panel (very expensive), but you can try replacing the LCD controller first (around $80~100).

Colored vertical lines with sound no picture
im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.
