Service menu 7000 series

[moosecyp]

Hi can anyone help me. I stupidly went into the service menu of my ue40es7000sxxh to change the region as i was scrolling along the regions it got to panama and without pressing anything the tv switched off. And what is happening now is the tv switches its self on and off all the time . And the remote has no effect at all. I have had it unplugged from the mains all night and it is still the same. and i have left it switched on for 4 hrs and it just keeps powering up and down . Cheers Geoff
