After automatic reboot problem I had after updating to the latest android oreo 6.6510, my tv 55XE90 started to periodically reboot by it self. I tried to fix the problem with power reset with no luck. then I decided to do factory reset first unplugging the tv from power source for about 5 minutes and then replugging power source holding the volume - and power key simeltanuesly. then the LED light turned green and I was waiting the tv to start. what happened was after a couple of seconds to minutes, the tv gave me some sound with black scree and then remained like that. i repeated the the factory reset proces with no luck. All I have now is red blinking LED light 8 times with black screen. Your help please!!!!
