Re: GTOCP4 Not powering up

Woody Schlom

Even if that power supply has worked in the past, try a different one.  I’ve had one Pyramid not only die on me, but almost take a couple of other pieces of equipment with it.  Smoke suddenly coming out of a 12v video monitor was the first clue something was wrong. 


And when I did a simple test of the PS with a volt meter, it tested fine.  But it wasn’t.  Never did figure out what the problem was with that PS.  But everything worked (and still works to this day) with other power supplies.  So that one is gone now.  And I’ve also retired my other older Pyramid to emergency spare status.

Unplug the power cable, from the box and blow on it, and plug it back in. 🙂

The person who bought my Mach1 is having trouble. He’s using a Pyramid power supply that has worked before. He set up today but the CP4 light isn’t coming on and the Hand Controller doesn’t start. Looking for troubleshooting tips
