You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

SOURCE: Hi, my Samsung 40" LCD TV's
Actually no board/part is defective - you have a bad contact that when the tv heats up it fails. Since the screen goes totally black but not light goes out on the tv and the sound still goes on then the problem is in the mainboard or the connection between the mainboard and the t-con board - a wide flat cable.
You must open the tv and reseat the connecting cables. If this doesn't fix it then the problem is in a soldering: you will have to remove the boards and check by eye every single soldering - redo all that look suspicious; you will probably have to move the components with your fingers to clearly see a bad soldering in their pins.

Basically it is problem of LCD Panel (screen) however some times T-Con board replacement fixed the issue (T-Con board is part of lcd panel but some part shop sell it separately). Main board is not related with this kind of problem.
Required T-Con board is available in ShopJimmy.com (click the link to view available boards)
If T-Con board replacement does not solve half screen vertical lines problem then LCD Panel will be replaced and it would cost approx new tv price.
Hope this info will help.
