Guys,

Good news. No more LED's stuck on. You totally helped me out. Jed was right. I found 2 traces that needed a jumper. So much for my 'continuity is all good' comment. Odd how I replaced the battery 2 years ago and it was working great until last week. This corrosion thing is a bitch. Turns out the the issue was related to IC 30 pin2 and Pin 3 needing jumpers. Now the whole keyboard seems to work as it should EXCEPT for this one thing:

I can't seem to get the tape to work. I ran the test mode for A/D and cannot get LED's 1 and 8 to come on. Only 1 and 5 do, and the VR6 and VR7 adjustment only moves 1 up and down. Thoughts?

John
