Customer Question

Hi,
I have a Denon AVR-1604 which has been stored for a while. When I turn it on it does normal things for about 5 or 6 seconds then turns itself off and leaves the red power LED blinking. Can you help me? I am competent with a soldering iron and have (although hardly use) an oscilloscope.
Thanks
Justin

Hi Jack, my name is***** are your extra questions?
Expert:  Jack replied 1 year ago.

Actually posted here by mistake bu lets see what we can do

Expert:  Jack replied 1 year ago.

Was the denon working when you stored it ?

How long was it stored and how long has it been plugged in now ?

Customer: replied 1 year ago.
I cant really remember if it was working or not. I think it was. We moved to France 3 years ago and I've only just got round to refitting it. I wanted it in for Christmas with the family.
I did have all the speakers connected quite correctly I thought and a few inputs from the TV and DVD via phono jacks (red, white and yellow).

I have nothing but the power lead connected now. Still the problem persists.

O.k then right now this could get tricky , if this unit was not working when it was stored then anything internally could cause this .

If it was working then perhaps we could be talking about dried up/vented caps that do not like to be left unused for extended period and who may just come back to life after a few days being powered but I would not count on that too much .

Right now the only thing I could offer is the reset procedure and if that doesn`t work then it would mean repairs and I`m sorry but this type of repair has to be done hands on , I cannot possibly guide you through the circuitry from here .

Here is the reset procedure and then I will opt out and repost your question , I posted here by mistake anyway .

1 Switch off the unit and remove the AC cord from the wall

outlet.

2 Hold the following SPEAKER A button and B button, and plug

the AC cord into the outlet.

3 Check that the entire display is flashing with an interval of

about 1 second, and release your fingers from the 2 buttons

and the microprocessor will be initialized.

NOTES:

• If step 3 does not work, start over from step 1.

• If the microprocessor has been reset, all the button settings are

reset to the default values (the values set upon shipment from

the factory).

Good luck

Let me know if that does anything

Customer: replied 1 year ago.
Nope, I done it several times and still the same.
Expert:  Jack replied 1 year ago.

O.k then you would need a local tech. and I`m not sure this would be a good idea VS a new unit .

They came down in price quite a bit and denon is still an excellent choice , that is what I have myself

Expert:  Jack replied 1 year ago.

Now I can repost your question for other techs to see but I would be very surprised anyone here can offer more than what I just gave you.

Are you in the US?
Expert:  Jack replied 1 year ago.

Actually in Canada , Ottawa, ontario

Expert:  Jack replied 1 year ago.

I will repost your question

Customer: replied 1 year ago.
I'm just wondering what kind of cost I'm looking at? Money is tight as always! What would be an equivalent model today? I bought this one when I was at University many years ago.
Customer: replied 1 year ago.
Thanks for your help Jack if you can still see this.
Expert:  Jack replied 1 year ago.

I can still see and reply to this , I just posted your question and as I suspected no one is coming forward so I will opt back in

Expert:  Jack replied 1 year ago.

As far as repair goes now I will be talking in US dollars and you will have to translate that to euro .

In the USA , depending on the parts required of course but say for a common problem like a defective channel output circuits you could expect a near $200 repair.

The French may have different rates but one thing I`m fairly sure they also have would be a low or free estimate so you would have nothing to lose taking it to a shop for an estimate and take it from there .

As far as new denon goes then the AVR-S or AVR-X serie would be a good choice .

For example you can get the AVR-S900 (900 watts) for around $350 and its a 7.2 surround system , the avr-s700 is the same receiver but with 200watts less and sells below $300
