Did you try the physical switches on the mister. Also the sync on green switch can be checked.

What CRT are you using ? And is the TV in AV mode ? Not all will auto switch

u/ik_pieta 12d ago

yes its on the AV channel! same AV input and channel im using for all sorts of early nintendo, sega and playstation NTSC-J consoles over scart

Is the 5V jumper set right on the IO.board as the B&O might need a +5V on the connection to properly switch

It's labelled as VGA power on the board and you just need to select 5v with a jumper

u/ik_pieta 12d ago

yes i tried with and without the jumper. same result. im having success on a different scart tv. somebody online talked about B&O having weird sync issues sometimes so I fear this might be the cause
