Unit was working fine. Hadn't powered it up in about a month and when I did the led displays (numeric and led) were all blank. Checked +5v, +15v and -15v power supplies for level and ripple and all were fine. Checked that +5v was getting to front panel display and it was. Looks like something on the processor board? Any suggestions where to start?
