I have purchased a new Samsung 2020 55" TU7000 Crystal UHD 4K (UE55TU7000KXXU). I've been experiencing problems getting it out of standby.
Basically I need to power on and off at mains. I timed it and left it for 4 hours afterwards and was fine. it its about 5 hours and will not come out of standby - I try holding power button on remote and it will occasionally come on. Other times no joy and I have to switch off and on at mains.
I've factory reset the TV. pefrormed SW upgrade. checked various settings. Ran self check or siagnostic. Tried a different power socket. Changed batteries in remote. Tried another remote (I have 3 Samsungs) all no joy.
Been looking at various FAQ's online support and tried pretty much averything but been unable to speak to technical support. Any ideas???
Apologies for replying to an old thread but we have what seems to be a similar issue with a different model TV - see https://eu.community.samsung.com/t5/tv/qn95b-going-into-deep-sleep/td-p/6390356
Any solution or ideas?
I've just a repair agent out who suspects a faulty board - they are going to replace it - not sure if that will fix your TV. I will see if ours gets resolved.
