OPEC led is lit directly on

I have a Crown macrotech 3600vz and for a while now the OPEC led is lit directly on one side, can anyone tell me how to solve it?


  • The amp has a heat distress situation. Refurbish output devices, remove and reapply thermal paste.
    Also, after the refurb, do the bias adjustment and make sure the fan is spinning normally. Clean vent ducts on the side to assure proper ventilation. Also, ODEP is linked to overloaded outputs with too low Z speaker network. Respect loads.
