Just as described, when I lose power, it resets all settings and goes into demo mode (easily back to normal turning off when the demo message appears and turning back on). But it does it every time it loses power

I am a hobbyist (not a professional) so please be gentle...
I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)
I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,... -

D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical... -
Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.
Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about... -
