Question about Televison & Video
Usually a faulty inverter board.
The inverter board supplies power to the LCD backlight system. When it is faulty it may fail after few minutes. The TV will lose picture or enter in standby as soon as the inverter fails.
If instead TV shut down completely, then you have a faulty PSU board.

Parts must be tested before replacement. The inverter is an high voltage board, and must be tested by a technician reading voltages in and out.
