No, it's not the LED strips, You have a T-com board problem, so replace the T-com board.

You could have one of three problems. One is really expensing to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went back. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable and clean it off a bit and put it back. If its still there, you have a deeper problem.

Install the forteManager software that comes with your LG LCD monitor. Go to the Options tab and choose Restore which will set it back to factory settings. For some reason some monitors come this way out of the box and this was the only way I was able to solve the problem with mine.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.
