After a new unit working fine as it should for 3 months all of a sudden all 16 step lights are illuminated (none of the 6 led's for mute/roll time sig are on) and don't seem to work. Tried an eeprom init and still nothing in pattern mode. any ideas? When i turn it on it makes a loud noise like all sounds triggering at once.

Opened it up and I'm now getting 3.7v on the 5v lines coming off the power board and I believe it's the 5v that runs the sequencer. It appears as though the headsink slipped down on the regulator and bridged the 3 prongs causing a short. Going to rebuild the power section and go from there. Just a heads up to everyone to secure your headsinks they don't stay on the regulators tight enough to just leave as is

did you get this resolved? Pretty sure mine is doing the same thing. I get the correct voltages, but i dont think enough current is going to the sequencer and its resetting.
