Our GA75 compressor lost power on the display unit, yet the incoming power is fine. We checked all visible fuses. What can be wrong? Where can we look

Are you talking about the one above the motor?

Have you opened that up ?

I can't see the inside, but there's a good chance there is more electronics and possibly a fuse or two in there.

If you find DC power in there (possibly anywhere from 3 to 50 volts or so) you can try reseating/tightening the connectors. If that fails, you may have to replace it.

Service

You need to get them serviced, basically theyre overheating, check oil level, cooler and ventilation.
Are they in a hot room? You may need to fit extractor fans to cool the room down otherwise they will cook themselves
