Dear tech Gurus I bought an used Autotune module but the unit never turned on. out of curiosity i disassembled the entire unit and this is what i found on the board. I tried to contact DJ but they were unable to help. my google skills explains me that the burnt component is a diode. Currently I tried t power the unit with a 9V adapter (9.62V on multimeter) and tested the output at the burnt diode which was 2.64Volts. I gave direct 9.6V to the output side of the diode still the unit did not turn up. techies pls help to bring my autotune back to life.
