Re: BIOS flash ROM
Being that you have taken the unit apart and have access to the board, I would try a BIOS discharge. I don't know if it's going to help, but it's worth a try. To do so, disconnect the CMOS battery from the unit. If it's like most other units, it will just be a plug. Once it's disconnected, take some kind of piece of metal, whether a wire or tweezers or whatever, and short the two poles on the system board inside the socket the battery plugged into. IOW, use the metal in such a way that touches both at the same time, to make them as if they're connected to each other. Do this for at least ten seconds, then reconnect the CMOS battery and then your other needed peripherals (power, monitor, keyboard, mouse), and then try starting the unit to see if it works. What this does is reset everything in the BIOS to their default settings. Again, I don't know if this will help, but it may.
Before reading further, if after the above attempt it still doesn't boot properly, but it DOES boot into the main BIOS screen, get a picture of that main BIOS screen, as it might be helpful.
If the above attempt does not help, I would contact barry777, a tech for the company, at barry@minipcunion.com. If you were able to get a snapshot of the main BIOS screen, I would include that in the email, along with your other two snapshots.
Hopefully the unit isn't bricked.

Re: BIOS flash ROM
The battery is soldered on board. I've soldered it out and close contatcs with tweezers for 10 sec or above, but it had no effect. Still have no image. So i soldered it back.
There is a small reset button on board, but few tries to hold it for 10 sec or above had no effect too except that led light change to red while holding button.
Thank you for your patience and advice!

Re: BIOS flash ROM
Oh wow. That's interesting. I wonder if my T6 Pro stick PC is like that.
