My ue40f8000sxxtu started to show a white screen and after I turned it off for a while it came back on ok.
What could be the problem?
I would suggest a screen test , Support-Self Diagnosis-Picture Test. However if that is ok then monitor it for now but if errors show up at any point could indicate a fault with Board/Panel. In this instance would be best to Contact Samsung as repair will likely be necessary, you could use Remote Support or call on 0330 726 7864.
