If Unit turns on then shuts off ater a few seconds. Dc protect circuit is probably activating due to shorted output transistors. This is very common on Denons. Unless you are a Qualified technician I dont recommend doing this yourself since when outputs short it usually opens up emitter resistors and shorts pre-amp driver transistors also. Not a easy fix for someone who does not do it for a living. I would charge around $125 to $150 for this repair at My shop kstahl65@att.net
You may have had to low of Speaker Impedance Probably on the Front ch's or unit just got to hot and amp failed.

Maybe this is just a fuse.

Sounds like you may have blown the amplifier output stages. If it won't turn on with the speakers disconnected, it's definitely faulty. Will need expert repair.

My dennon reciever will not turn on


Check if there is a fuse on this unit. Very likely there is and it may have blown and in that event it will not switch on.

I turn the power on to my RX-318 and a few seconds later it sounds like something else is kicking on....then I dont hear any sound from my speakers. I dont know if theres a fuse blown, the amp is going out...


Sounds like the automatic circuit protection. Check to make sure you have good speakers and NO shorted wires to them. Too many spearkers conected to the outputs will cause the same problem.

it sounds as if your using HDMI out of the DVR to the TV which is fine but the better way to do this is to use the Component connections (red, Green, Blue) plus optical or coaxial from the DVR to the reciever and Component connections (red, Green, Blue) out of the reciever to the tv

Poor sound quality from Hi-Fi


It may have a ffew components in it that have failed, the only way to know is to have it checked by a technician. Call the nearest electronics service center to your home and ask them if they repair this brand. If they do not, you can ask them if they know who does in your area. Tell me where you are at and I may be able to find one for you. It does need troubleshooting to determain the cause of your problem.

Harmony remote with Harmon Kardon receiver


HK AVR 347-I took it back- everyone was frustrated and the verdict was that it just doesn't work. I have a Dennon now and it doesn't sound as good as the HK but it works most of the time. Not sure it the Harmony is the problem. I'm reading the Dennon manual now and it seems the Dennon remote can do what the Harmony is trying to do. Harmony support is awesome and we'll keep trying. Sooo- was there a trick to it?
