try un plugging the tv for 5min or so ,if this doesn't work and providing the tv is under warranty,and you have the bill of sale,contact samsung direct they will organise a visit from a engineer .its a common fault on samsungs and samsung will be aware of the fault ,although they won't admit it .most likely be one of three capacitors on the power board .samsung have always used cheap electrolitic caps on there powerboards.easy repair.if for some reason you haven't got a warrenty lol then get back to us on here and I will let you know what caps and voltage are needed for the repair .all I ask of you is do you have a soldering iron and know how to use it .
