Hi, apologies in advance if this is posted in the wrong place. I've got a Sharp LC-32LE351K LED TV and I have done for around 18months. I was watching it today, paused a DVD to step out of the room, came back in and I returned to a black screen. No power light. Nothing. Tried unplugging it. Switching it on and off. Still nothing. Totally dead of power. Is there any common problems with this unit I should be looking at trying to get fixed? Any ideas of cost? I read online something about Sharp TV's having power issues but I've seen all manner of different problems reported. Thanks in advance for any help!
