Default Harman Kardon 930 lost channel. Hoe to trouble shoot ?

here is a tip,

wire an outlet box with a duplex outlet and a switch.

wire the outlet so the two outlets are in SERIES and in series with the switch..

Plug your unit into one outlet and plug a 100 Watt INCANDESCENT light into the other outlet.

Use the switch to turn on/off the power. This makes it easy to turn OFF all the power when you are working on the unit.

Also the bulb will limit the current if there is a fault. If the bulb glows brightly, there is still a fault and this will protect the new parts that you just put in.
