We have been running this machine for eight years without an issue. Turned it off one night to find that when it was switched back on the control would not boot back up, just the feed and rapid led's would flash. The four leds on the mc161 card are solid which normally means a scrambled memory. Flip dip switches 1 and 3 to reset and reboot but no joy. Get mazak in who can't get it to reset either. They recommend getting a new mc161 card. Find a reconditioned one available from the US and have it shipped over. When it turns up it is a mc161c-1 where I wanted a mc161c. Everything looks the same and my Mitsubishi contact says I should be fine transferring the processor chip and trying it. Get all this done and plug it in and get the same solid lights and a refusal to restart.
Do you think it is right to keep looking at the 161 board or is their another board to look at?
