I have a 2½ year old Samsung Qled 8K R900RA 65" TV, and now it's somehow "software" broken.
After I used my Apple TV to broadcast a video to the TV from a mobile phone (which we have done many times before), and we turned the Apple TV off.. the TV suddenly started shutting down by itself.
Now it's: I turn TV on (plug in power), after 20sec it turns off and restarts, on for 20sec and so on.
If im quick i can enter the reset menu and reset to factory settings. And then the tv starts as factory default and WORKS! but it only works until i have finished the setup/installation procedure, then its back to power off after 20sec.
It's a really annoying fault. Seems very software related. The has a OneConnect box, where all cables and power supply is.
I have tried all kinds of reset. disabling auto power off and all that. Only have 20secs from power on though.
Any clues for what this can be?
Hi @Mardahl if you still have this issue can you check you have the latest firmware 1325.2 which became available May 2022 https://www.samsung.com/uk/support/model/QE65Q900RATXXU/
if does not solve the issue try a soft Reset by holdng in Power Button for around 5 seconds till the Tv reboots and/ or unplug Tv and cables for around 5 minutes. However may need to Reboot Router or change the DNS Settings . Go to Network-Network Settings-DNS Settings. Change from Automatic to to 126.96.36.199 or 188.8.131.52 (Google Serves) alternatively 184.108.40.206 or 220.127.116.11 (Open DNS) Same information on DNS here https://www.lifewire.com/free-and-public-dns-servers-2626062
However if to no avail possibly a fault with the Tv.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
