Tried everything, I give up 😅 Thank you both Lotas and Diah for your time and effort! Really appreciate it! I think I will let the TV sit in a basement and wait for someone who would be selling the same TV with a broken screen.

Best of luck to you all and Happy Easter! 🙂👍

As I understand since the mainboard is problematic and I tried to reinstall the TV through settings, something happened during the process and the TV is basically stuck now. The problem is that it doesn't not want to start the reinstall process through the USB ports and I looked up the 6 blinking red light error. It has something to do with standby 5v/12v line....

Hi, lotas I have found the same file and did all of the steps. Tried with two different USBs, both of the TV USB ports. File is upgrade_loader. Downloaded Rufus and formated USBs with MBR mode. The USB sticks light once inserted into USB ports but the situation is still the same. TV turns on, Android logo and just black screen (sound can be adjusted). Is there anything else I can try?

Renamed the file to upgrade_loader, inserted it into USB, turned on the TV and the same thing. Android logo comes on, TV blinks 6 red lights and I can only adjust the volume....

I have been looking where to download it for a while, maybe you have a link? I would really appreciate it.FOUND IT!

Hi guys, I need some help with my 55oled803. I had 40+ red light blinking error nd have downloaded the NVM file and reset the TV. Everything was working but I was stupid enough to reset the TV through the settings. Now the TV turns on and I can only increase the volume. The red light blinks 6 times nd the screen does not show anything else. I know it's a problem with a main board. I have tried inserting an USB with a software but it would not instal. What do I do?

Thanks for any help. I am new to the forum and still learning things....
