AVR 510 memory loss and s-video problems

First, it won't retain any of it's settings when the unit is unplugged for any length of time. Is there any documentaion on how to fix this? Second, the s-video monitor output has burned out for the third time since I bought the unit new about 5 years ago. Are there any known issues with the 510 regarding this?

In the event of the memory lose, you may check the capacitor C216 on the front PCB and replace with a good 0.047 Farad 5.5V.

How do i factory reset my Harman Kardon avr 55 receiver


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.

No sound regardless of input. front panel lights up and functions as per inputs however also noticed pwr supply fan and internal heat sink fan do NOT turn on. Any debugging tips appreciated! Thank You...


The power supply has to be on to some extent or it wouldn't light up.

Does it tune FM? That would indicate some life.

No sound? Is it Muted or a tape Monitor selected inadvertently?

One side louder than other in all modes.


Hi there.
Have you tried to connect the left speaker on the right wire.
If that's ok check the balance setting on the unit or volume on each speaker.

My unit has power, but it won't turn on at all.


This means that something is seriously wrong with the unit(blown amp, shorts, opens, etc.) however, you can reset the unit by unplugging the unit, holding the A and B channel buttons on the face of the unit and plugging in the reciever. the display should flash at 1 second intervals. if it doesn't stop flashing on its own then unplug and replug and you should be good to go! good luck.
