I've got a DE Maverick that has a few issues. The first is a battery corrosion problem that is nasty. It's most likely why the pin is more or less dead. General lighting comes up, it whistles, then nada. The DMD is dark. The CPU came out and pins just fell off the thing, it was sad! I will be posting pic to show what happens when you forget you pin. The next issue is the DMD. The controller has one "power" connector that has +5.03vdc on what looks like J1. The DMD driver board has +18.55 on J7 pin 1 and +5.03 on pin 4. The lm7805 reg on the driver board has a good +5 output.
My question is about the high voltage supplies. The pin database schematics are ok until you get to the page that shows the schematic of the HV supply. Does anyone have a copy of that part of the schematic? Can anyone provide a hint on what the correct voltages are and where to find them?
ANy help in figuring out what's not happening with the DMD would be appreciated!
Thanks
Michael
