Pioneer SC LX87 with DC voltage at the amplifier output

If you get the flashing MCACC LED indicating that the systems diagnostic has detected DC voltage at the amplifier output there are a couple easy checks before it needs servicing.

This same method applies to some other PIoneer amplifier units.

First, check all fuses are intact.

Second, perform a power fault reset by pressing and holding the ‘Tune’ and ‘Multi-Zone’ on-off buttons for 3-5 seconds.

Check to see if all is well. If not, it is time to contact your local service repairer.
