Hi there Toangel and fellas, have gotten into an issue after having a low voltage outage, my OLED803 is not turning on and the led red light is blinking without a visible pattern. Some years ago with the same exact low voltage outage I had it repaired in a single day, now in the same service they ask for a mainboard replace for a whopping 750 euros.

My initial thinking is that as I am from a small rural area in Greece that they didn’t replace the mainboard but fixed it rather easily by synchronizing the TCON somehow as having the specific mainboard in such place is unlikely, power reset (holding the power button, didn’t work) any idea what can I do? Maybe disconnect the tcon and do a power cycle then flash the firmware from the .bin again?

Or any other ideas?

@Toengel, it was My USB STICK that needed to be formated to sub 8GB, and a combination of holding the joystick on the down position when plugging the power cord(maybe? it wasn’t booting otherwise).

I had already received the “N V M.BIN” and it managed to get flashed, the TV is fixed.

Thanks a lot!

Your help and contribution of the required file was great.

This TV is notoriously easy to get in safe mode after power outages, I hope the device will live for another 2-3 years.
