20 Most Recent Harman Kardon AVR 100 Questions & Answers

I believe he avr-5 has 6 channel inputs, what you will need is a dolby digital 5.1 and DTS outboard surround sound processor, say an item as the Technics SH-AC500 decoder, a Harman Kardon Signature 2.1 DTS version outboard processor/preamp, and many others on the market by different manufactors, Run the discrete audio outputs from the Processor into the AVR 5`s 6 channel inputs, select 6 channel input or DVD inputs on the receivers selector and your good to go. Be sure you are playing Dolby Digital 5.1 or DTS encoded material.

If you put the new fuse in the same way/place the old one was, then that is a non issue. Assuming that you are replacing with the fuse they spec, fast acting/slow blow and the correct amperage/voltage..then losing a fuse that quickly indicates somethings failed inside, shorted to ground. That would either be repair or replace the unit.

It is trying to input a signal via the Optical digital input. You need to switch the input control on the front panel or remote to Analog.

It is important that you get a new remote controller for the Amplifier as most functions are easily done from the remote when you need to sit and adjust.
It is best to get to the nearest dealer to order for the remote.
Now the DVD and the TV can be connected to the rear inputs that are specifically marked. Connect the DVD using the digital coaxial cable or the optical cord. You can set the amplifer to DTS or 5.1 and play a DVD that is recorded on DTS.
this will give you the best option of sound. Also make sure that the speakers front and rear and center and teh surround are placed at EAR level. the sub woofer can be tucked around as the BASS can be heard from any position.
A test signal can also produce the sound level calibration for the room.

Check the impedance of the speaker wires going into the amplifier. It sounds like at least one set of speakers is overloading the amp (shorted, or almost shorted)

One can not say without some significant details. Maybe get the manuals for all involved products and see how it's supposed to be done.

Here's one...

Yes. One, for whatever you want to feed it.

if you have your speaker wires plugged in when you turn it on try unplugging them and turning it on to see if it turns off again. if it stays on after the speakers are connected you have a speaker wire shorting somewhere or a blown speaker and the amp is turning off into protection mode. if thats not the case check the fuses inside of the amp and make sure they are ok. and while its apart use a can of air to clean off the circuit board to make sure there isnt ne dust causing a short on there also.

Hi,
What we are doing, in this case is looking for a shorted out speaker system, or wiring to speakers, or cables or components that are connected to the receiver that have a short circuit. This is what I would do if I were called to your house to debug your sound system.
Follow this procedure and see what happens:
1 Disconnect one set of speakers at the back of the receiver and turn the power button on again. See if it stays on. If not, go to step 2.
2 Remove the next speaker and keep repeating the test. If you don't find it, go to step 3.
3 Disconnect all of the equipment connected to the unit, one piece at at time.
Somewhere along the line, the receiver may not shut down. If that is the case, go to Step 4. If it is not the case. Your receiver will need professional servicing.
4 Identify the the offending cable(or component)and replace or service it.
I hope this solves it for you.
Best Regards,

You either have a shorted output transistor on the left or right channel or the voltage regulator in the power supply is shorted. It will continue to blow fuses until the part is replaced.

Humming noise is usually a sign of a roving fan and this humming noise comes when the fan is moving with difficulty all you have to do is get a repair personnel to service the unit and is not enough to get the unit replaced.
Hope this solution has been helpful?
Happy new year

Hi,

If you've unplugged the speakers (the only short externally that will cause the unit to shut off), and it is still shutting down, then it has a power supply failure and is in need of service. This could be as small as having the capacitors replaced, or it could require a whole new power supply. Unfortunately the unit is in need of service though.

The symptoms you describe currently sound like either a mechanical/contact failure of the power on/off button to the unit, or a failed(short circuited) self healing spike arrestor capacitor across the mains switch. They fit the capacitor to catch spikes caused by contacts arcing on power up of the amp. If the switch seems to operate in a mechanical sense OK, then I would suspect the spike arrestor capacitor as the culprit. The problem you have been having with it not firing up, may relate to dry solder joints in the output stages, putting the amp into protection mode. It may also relate to the problem you have currently, a dodgy power switch if the lights go out completely. hard to call that one without checking out the amp first hand. Was more interested to see if the 2 problems were related.


Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Switch it off quick & take for repair it could be dangerous risk of fire water & electricty do not mix
