Here are the actual voltages taken across the PIC pins.
27 and 28 - 3.8 volts
27 and 1 - 3.0 volts
28 and 1 - 0 volts
Everyone is going to have to excuse my lack of knowledge of DC based electrontics, but when you ask what the voltage on a pin is (ie What's the voltage at pin 1, or what's the voltage at the 3.3v regulator) I don't know how to test for that. I need two places to stab the meter. If it was a normal AC 120v circuit I'd stab the neutral bar... I figure if I do that here, I'll fry whatever I'm trying to test. I'm more than ready to post any readings anyone can think of that may help, but in all cases assume I'm an idiot and give me a place to stab each probe.
I'm ready to start removing and replacing components at this point... I have 3 more complete sets to assemble on hand, but obviously I don't want to try and desolder a 28 pin socket at random, so if we can narrow it down with some confidence I'll crank up the desoldering equipment.
Jess_her - I hate giving up on something so I'm not ready to throw in the towel just yet, and I need 14 functional Lynx expresses for my display (which means I want 15 on hand for the season). At present I only have 14 including the problem board, so I also want to make sure I can replace it before giving it away. On the other hand... too many more days of this and I'll probably be ready to give it up at a heck of a discout
