I have a 707 that powers up, but when it does it is in Track Play.(but
it won't play a track). It doesn't respond to "Play" or almost any
other command. The screen patterns are almost full except for a few
flashing dots. If you hit shift and then some of the pattern numbers,
they'll appear on the screen, but disappear when shift is released.
Oh, and the voice buttons do work.
I tried resetting, examining the circuits. Just a few revision jumpers.
Any ideas before I give up sell it
