Hello there, I recently bought a second JVC Smart Android TV for my bedroom (Model LT-50CA890 50") I already had a 58" version of the same TV in my sitting room so I knew that they were good. For the last 3 to 4 weeks whenever I switch the TVs off at the walls then they lose the inputted time and default back to the 8th of Feb 2021, I have tried it with get time from internet source turned on and off, I have plugged tp link powerline adapters into both TVs and both on WiFi and nothing works.
While I can set the time I don't want to have every time I switch it on after I return home. Both TVs are on the latest software and have the same gmail account and have location on. I have the timezone set to Dublin as I live in Ireland, I can't access YouTube or Netflix without setting the time and I couldn't find any fixes online.
Any help would great.

Thanks
