HARMAN KARDON 630

Troubleshooting Guide

Processor Reset
In the rare case where the unit's operation or
the displays seem abnormal, the cause may
involve the erratic operation of the system's
memory or microprocessor.
To correct this problem, first unplug the unit
from the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit's operation. If
the system still malfunctions, a system reset
may clear the problem.
To clear the AVR 520's entire system memory
including tuner presets, output level settings delay times and speaker configuration data,
first put the unit in Standby by pressing the
System Power Control button 2. Next,
press and hold the Tone Mode 8 and the
FM Mode Selector ^ buttons for three
seconds.
The unit will turn on automatically and display
the RESET message in the Main
Information Display Y. Note that once you
have cleared the memory in this manner, it is
necessary to reestablish all system configuration
settings and tuner presets.

All it needs its a hard Reset press the power button once its on standby mode press surr botton for 5 sec and it should reset

turn OFF avr 300 and unplug the ac power supply and also unplug the speakers terminals,input signal (optical ,coaxial,video1,.etc) after that you turn ON AR 300.

You have a memory cap ,usally located on the front display,that is most likely defective.measure voltage on cap with unit off should measure at least 3-5 volts

speakers may not be good. volume might not be up high enough. settings may not be right on reciever. i advise you check the speakers first by plugging them into a different stereo. if they don't work, inspect them to make sure they're not blown (cracks in the cone of the speaker). if they do, hook 'em back up and check to make sure there's no headphones plugged in or any settings on the reciever that say speakers or external speakers or anything like that are powered off. hope this helps.

The problem is with the actual eltromechanical element on the volume control, my avr 300 does this as well and I'll let you know the secret to avoiding it. There are small indents on the volume control as you turn it, if you leave it half way between indents, it will periodically start reading volume changes, if you're lucky it will go down, if you're unlucky by the time you've noticed it act up your speakers are blown. When you change the volume, make sure the control rests in an indent and the problem will never crop up again. A simple solution if you're the only one that uses the receiver.

I don't know why you'd set the Peavey to 2 ohm to drive 8 ohm speakers??? My other thought is... I wonder if the phase is correct. try reversing one of the speaker wires Left or right side.
