I switched my TV off at the power socket this morning and tried turning it back on this afternoon with no luck I have tried the TV in many working sockets and left the TV unplugged for 5,10,30 and 60 min intervals this has not worked either there are no flashing lights which to me indicates there isn't any power running to the TV
It has done this a few days ago but when left over night unplugged it fired up straight away when the technician came to have a look at it
