Dashboard functional but completely black screen

[Olivierftw]

So i have a bunch of ex rental controllers that im flashing, now my good dashboard of my testrig died(the button doesnt click anymore) i have tried like 3 other dashboards and all act the same, when i power up it lights up 1 second then goes full black like dead, but its still functional, can turn on lights and change speed modes, any idea’s on what the problem may be?
