LG 32LH5000 will turn itself off suddenly, the red standby light will flash for a few seconds, then the screen will flash and go off again, and it keeps repeating this until I unplug it from the mains. It doesn't always do it, but has gotten more persistent to the point where it switches itself off all the time now
