I have a version 7 PS2 and a DMS3 v2.0
My problem is that I cannot play PS2 backups, but everything else works fine.
I know that when you test for continuity with a multimeter between GND and a BIOS pin, I should get 0.000 (multimeter set to 2K ohm).
However, I get 0L (no connection) on all but the pin to which wire E is connected. When I touch GND (or the copper edge) and wire E, I get something like 0.985. I get the same reading if I touch wire E and any of the the spots circled in green below.
I've checked for a bridge near all of these spots, but found none.
What can the problem be?
