They very well could be part of the issue! The corrosion gets into the board and actually creeps along the traces. Destroy enough traces, board stops working.

Yeah, I mentioned that in my first post. It may have popped out during transport, or maybe it was like that before - dunno. On quick glance I couldn't tell which way it plugs in, and I don't want to plug it in the wrong way and fry something! I'll go out and have another look. Hopefully it can only plug in one way.

Ah. Good point. Though I know the guy wasn't thinking of that - he said he knows nothing about arcade games. I'll look closely at the area surrounding the batteries and see how it looks.
Thanks Level42 for the links. I ran across those last night when I was searching the boards here for anything relating to Defender restoration. The lithium battery idea sounds good. I haven't read that page yet, but if it's a simple/quick conversion then it's a no brainer. I don't want to go down the road of that multi-williams board at this point. I'd like to keep it as authentic as possible.

I plugged in that monitor board (yeah, it only goes in one way). Fired up the machine. First I see a yellow hash pattern, and then after a while it goes red and then I start hearing a sound that alternates between 2 frequencies 2 or 3 times per second (kind of like a police siren, but much faster). Here are pictures showing each of the screen images, as well as a picture that focuses in on the battery area. It doesn't look to me like the corrosion is enough to make it stop working, but I'm no expert.
Oh, and after I giggled some wires, the 4 led's went red (they were off prior to that). I also checked the voltages at the PS - 5.00V, -4.96V, and 11.97V, so that seems fine. Although I hear a high pitched noise that seems quite a bit louder than I'd expect it to be, and I think it's coming from the PS.
Also, could an expert have a look at picture #4 (above) and tell me if that coil that's hanging is a problem as is? I can see where it's supposed to go, but it doesn't look to me like that would cause an electrical problem. And if you see picture #5, there's a red wire that goes off the bottom of the picture, which is just dangling there. I'm not sure where it goes exactly, but I'm guessing it goes on one of those terminals next to the yellow wire that's by itself. Can someone tell me where it goes?
I would really appreciate advice on how to proceed!
BTW, monitor pictures are a bit washed out, but in person it's quite yellow and quite red, trust me. :)

Is there a defender manual available online?
