I have an Android TV KD-49X8305C that since the other day has started to reboot automatically after 1-2 minutes working.

The TV turns on perfectly but after a minute or so it reboots.

I've tried soft and hard reset but it doesn't work (when I choose on factory reset it doesn't do anything). 

I've also tried to remove apps but, even when it seems to work (they disappear), after the reboot the same apps are there. No matter what I do or change, after the reboot the status and apps are the same always. Tried the same starting on safe mode but the initial status is the same..

Any help? Has anyone seen this before? Our should I think on buying a new tv?
