Question about Denon Audio Players & Recorders

1 Answer

I have a denon April s470h receiver and was listening to it today on a low volume when all of a sudden the volume went to the max. Turned it off by the remote and a minute later the receiver turned back on at full volume, had to unplug. Has anyone had this problem?

Usually happens if there is a stuck button. Could also be a component like a capacitor failing.

SOURCE: overheating?

I know this post is pretty old, but I just came across it. I have a GTP-750 that I have fixed. They do run extremely hot which causes the rectifiers in the power supply to fail. I have the rectifier part numbers to fix it as well as cooling method. I have been running mine now for about a year after fixing it sometimes at high levels for extended amounts of time and the case is now barely warm. If you need advice or pictures of my setup send me an e-mail

SOURCE: AV-DV75 volume control not working

Hi Deebo check the following website good luck open the set and you will find the part number printed on the body of the component. NB.but i am in the belief that it IS your IC that is damaged.

The tact switch behind the panel is being pushed in by a defective front panel button, the small switch is bad behind the button, or the volume control IC is bad. Good Luck

SOURCE: volume issue

I have the same problem. When I adjusted the volume on the cable box, it was solved. Turn up the volume on the cable box, and when you use your remote, it's super loud, even at midway!

I'm not familiar with your unit. However, go to systems surround set up and turn up volume for those surround speakers you speak of.

I have a Denon Receiver, that recently started having volume problems. after listen to any source for about 40min to an hour, the volume either totally cuts out or increases to max volume. This condition...

The control section seems to have a thermal problem, when its cold it works, then warms up(metals expand with heat) it loses a connection. Can be either a solder connection or a component, these are found with freeze spray by a qualified technician.

Excessive noise in my speakers

usually, it is background noise. Scratchy background noise. Gets worse the louder I turn up the volume. I ran a test on all the channels and it seemed to be the subwoofer channel. I've unpluged the subwoofer but that didn't help. I have also noticed that my receiver doesn't turn up nearly as loud as it used. I usually watch DVDs at a volume level of about 15 on my Denon and that's quite loud. But now, 15 isn't that loud at all. I went to Best Buy where I bought all of this equipment and they immediatly told me it was suge protector issue and wanted to sell me a high-end surge protector. Perhaps they are right but not sure why it began rather suddenly. Probably not helping you much.

No sound when on internet radio, playtime is running, volume is not muted, internet ok

It was solved by turning the receiver off with the power button (not stand-by). After turning on the netradio did have its sound back. Apparantly it must be running some sort of Windows os.

Volume settings

Check that level setting for speakers as well as sound field are the same for each input mode. Some receivers will have different max volume levels depending on these settings.

why don't you both return these units and call Denon for replacements without these problems?  Sqeaky hinges get the oil.

Denon avr-5600 protection circuit.

My AVR 5600 has worked flawlessly for nearly 9 years!

Suddenly, when trying to play music (DVD or CD) through my LS32's (JBLPro), once I achieve higher volume, the receiver cuts off.... Using a Symetrex mixer, NO OVERLOAD light on the Denon, it simply cuts off!

Re-cut all the wire connectors... TV movies (5.1) work great at normal listening volumes.... but tonight, when cranking up music, the receiver simply cut off. Blinking light...
