Thanks for the quick reply!  I plan on doing some mm testing before I continue to rule out the harness.
Follow up question, any tips on getting out the seized screws?

Good Day just a few questions about my Nintendo red tent.

When I turned on my Red Tent for the first time,  Both monitors came on with white screens,
there was no audio. 

I have a feeling that its the power supply for the board that is not working, either because of
a burnt fuse or w/e.

I will be testing this with a multimeter in the future.

I have a few spare power supplies I recovered from a JAMMA system,  could I use this power supply
as a replacement for the existing power supply?  If not,  what should I use as a replacement power supply?
