Gigabyte GB-BXBT-1900

[YellowJacket]

Greetings, everyone!

Would need some help with this mini PC, the issue is - after turning on, PC starts, but there is no picture on the screen, no reaction on LED in external keyboard. Tested with another known good RAM. All voltages are present. Looks like BIOS issue to me, right? I tried binary from this site --> https://www.gigabyte.com/Mini-PcBare...upport-dl-bios ( version F9 ), but still same behavior. Note, I flashed only BIN file from that archive. Although, it says "1.0" in the linked site, but I have board with 1.1 revision. More hardware details:

Device: PC / Brix
Brand: Gigabyte
Model: GB-BXBT-1900
Board number: MZBAYAP Rev: 1.1

What do you guys suggest? If it is BIOS issue, should the firmware linked above work fine? If you need any other info, or original BIOS dump, let me know. Thanks in advance.

no video output on the VGA port ?

No, nothing on the screen.

Disconnect the cmos battery for min and reconnect. Not sure but see if there is a cmos clear jumper pin/point ? Are you able to get into the BIOS setup screen? Try hitting del once you turn on to try get into bios screen .

I was trying this as a first resort. But sadly, this hasn't solved the issue.
And no, I am unable to get into the BIOS setup, there is just nothing visible on the screen.
Anything else, I can try? I hoped, it will be possible to fix oroginal bios dump somehow.

You mention you only flash the bin file but the zip contained 3 files and a file that looks like script. Try flashing the bios again.

Correct me, if I am wrong, but command from mentioned script:

fpt64.efi -f image.bin

is for flashing from USB I believe. So if I want flash that binary with the help of the programmer, I just flash image.bin, what I did.

was there a jumper pin or something else to clear the cmos ?
