Really broad possibilities listed there.

1) First check that the adapter is outputting the correct voltage. Just plug it into the wall and check the other end without it plugged into the system. If the system isn't getting the correct voltage, that would be causing problems with operation.

2) If the adapter is working properly, then plug in the adapter and check the output of the voltage regulator. If the output isn't correct then replace the voltage regulator. There would be info online as to what the correct voltage output should be.

There could be several other issues causing the problems but those should be the first things to check before moving on to anything else.

With the batteries not working there could be something wrong with the DC jack, as there should be a small switch in it that switches between batteries and AC/DC input when the adapter is plugged in, and that switch could be stuck so a type of contact cleaner could help. I had a similar problem with something years ago and cleaning the input jack fixed the problem, I can't remember what item it was at the moment as it was years ago. Or the battery connections could be corroded and need cleaning, or a wire could be broken to the battery contacts.
I have no idea how to test the A/C adapter. My test leads are too thick to shove into the center. I figured the negative was the outer part and positive was the inner part?

The tricky part with all this is that I believe there are multiple faults. and yes I can verify it was a hard 1 VDC when it shouldve read around 34. The other leads on that pin adapter were pretty darn close to what they shouldve been (4.89, 489, 1.27)
