Question about Alesis Sr 16 Stereo Drum Machine
Open the unit and see if it has a battery that holds the settings. Check the voltage... it should be around 3 volts. If less than 2.5 volts replace it.
Verify the INTERNAL regulated power supply as the external you verified with new unit. The external is likely regulated within the D4 and either due to an overload or bad regulator may be below the voltage to run the processor. It is likely 5 volts and anything over 4.85 would be acceptable.
