Blinking standby light

[Aidy06]

Hi,

I was watching tv this morning and it suddenly switched itself off, the standby light started to blink. The tv won't switch back on, if I try then the standby light blinks fast for a second and then goes back to the slow blink. I can hear a faint clicking from the back of the unit when I try to switch it on.

Does anybody have any idea what the problem could be at all? The tv in question is a UE55JU6510UXXU. 

Thanks.
