Hi, I saw some other talk out there on Prophet 5's (I am aware this is a MOOG forum), but I thought it couldn't hurt to check here... I am working on a Prophet 5 rev 3 that won't start up. It was sitting around for quite a while, and after changing some decoupling caps and voltage regulators I got the voltages to hold at the right levels. But not a peep... occasionally I get a LED to flash, but it doesn't go into the tuning cycle, and then just sits there. I was told to check PIN 26 on the z-80 cpu, to see if it is getting a reset signal, other than that was wondering if anybody had some good ideas?
Take care.
