Constant clicking sound when my tv is on

Hey there, @Kareen1.

Could we grab a bit more info on this? What's the model code of your TV?

Hi Danny - it is a Samsung QE55Q90TATXXU - I bought the tv at the end of October and it seemed fine until a week ago.  The constant clicking sound is driving me crazy - plus the screen goes black now and again too.  Any advice would be most appreciated!

Does this happen on all channels/sources? Are you able to send through a video of this?
