Thanks Wayout!!...this is where I am getting my repair info from as well. It's an outstanding source.
I am not sure if the .5v drop from pin on the PS to connector on the Display Control is just because of the probes on the multimeter or if it's just losing power along the line....if so, certainly indicative of weakness in the PS. I think I'll try to test it under load and see what I get.
Regardless, the PS repairs above are my next step. I'm going to pull it an order all new parts and rebuild it with the 18 gauge wire mod. I have an awesome Hakko desoldering gun, which is seriously one of the best tools I have ever bought. If that doesn't fix the DMD issue, at least I'll have piece of mind knowing my PS is good and we'll move on from there.
My really big concern is that it went from blinking to dead as soon as I unplugged everything to test the voltages and then plugged it back in.
Do you guys know of any Multimeter Leads that fit well over pins? Ideally something insulated that will push over a pin and clamp down. I see some on Amazon, but it looks like they are hooks and it's hard to tell how big they are.
