The fault is with its main power regulator section circuit itself. Check all the electrolytic capacitors there. Replace them. Replace the main filter capacitor too.

SOURCE: Lines on tv screen
Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

Hi my name is Roety,
I can help you with your issue ,
Try the format, aspect buttons on the Box remote, if the line is there on every input and effect the TV menu your panel (screen) is bad.
A new panel would cost as much as a new TV.

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

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.
