Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

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.
