road hog playback wing

Yet another question.
So I am trying to help out some friends that have a Road hog.

Playback wing lights up. connects to the console, faders respond, touch responds but not correctly but I get nothing on the screen.

I can connect my computer to the wing monitor and it works perfectly.

It has a VGA to USB adapter but it is Not powered. They lost the power supply.

I feel the problem is the usb port might not be powering the VGA adapter.

Any help would be great. I just updated the console software to the 3.1.7
i have tried the calibrate and all that with no luck.

Thanks.
