OBERHEIM SYNTH

I just joined the group yesterday.  If you can point me to the previous discussion I'd appreciate it.  The problem is it sometimes powers on without a display, other times it's limited to 7 or so characters and other times the whole diplay fills up with random characters than change when I press the keys.  It seems too erratic to be a self-test mode.
