QLED TV keeps turning off restarting and turning off again

[Darkestblue]

Hi, 

18 month old QLED TV, model QE50Q60TAUXXU has today started turning off, restarting without any input, stays on for a minute or so with perfect picture, then the picture corrupts and the TV turns off again. This process repeats indefinitely. 

Have tried the obvious: soft reset, unplugged for a few minutes, cleared cache, closed all apps, changed remote battery, factory reset, and auto diagnostic (which gives it a clean bill of health). 

Problem is on all inputs and whether on live TV or Netflix. 

Any ideas other than the above would be appreciated!

Thanks

@Darkestblue this is one of the frequently reported issues with all these Q60 models starting from the R to T years. Screen fault so contact your your nearest service centre for both in and out of warranty replacement repair
