Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
- Does Samsung logo/ welcome screen show up repeatedly while TV turns On and Off itself?
- Is the TV 18 days old?
Thanks for the info.
Are there any troubleshooting steps you have already tried so far to fix the issue?
OK, it could be failing main board or software/ firmware glitch that caused the issue. I would recommend to unplug TV power cord from wall socket for 10 minutes to reset, replug back in, turn it On and check.
If problem persist/ reoccurs then it would be failing main board issue that needs to be replaced, required main board is available at following supplier for 30 Pounds (cross check the part number written on main board in TV before placing the order)..

Yes, board replacement is easy, no soldering word is required, sort of plug and play type work.
