I just find that crazy to believe that all 5 that I've tried have that same problem. Would reflowing the Southbridge solve that problem?

Have you any console which you've never attempted to read the NAND from? Can you test the points prior to soldering? It's possible you're reading the value back wrong or the multi-meter is faulty.

The two I've read from now read around 0.05v. I didn't read them when I first dumped them as I didn't have a multimeter. Even a new console I just got reads as .05v. The other readings are correct though.

I have one theory that may make this add up; it might be stupid, though. The only other difference between when I could read my Nand and now is that I started off using a regular 25W iron, now I'm using my Aoyue 968 and soldering around 400C. Do you think those two points could just be particularly sensitive to heat and are easily damaged because of it?

It could be your cable. Try cutting off all the wire tips, then restrip them and solder resistor leads to them. Use shrink tube to insulate the solder connection if you want. Also I think 400c is a bit high, I use 350c, but that's my preference.

Can you explain how you're measuring the voltage on these points? a pic of your meter would be handy with the value on it.

Ain't she a beauty.

But I measure all points the same. Black to ground point, be it J2D1.6, the AV Port, or whatever, then touch my read to the point. I feel like it couldn't be that I'm doing it wrong as I have no problem getting the other readings. I try to read it on the 20V and 2V settings just for the hell of it. No matter what I get between .05v and .18v.
