I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.
Hi I have the same receiver BUT all my lights and status indicators are
on but I have no sound in any digital input modes - i plug an ipod into
the CD input and I can hear Stereo, Pure Direct and Direct (it is the
sweetest ounding amp i have ever heard) but nothing else works. I can
pass thru to view OSD - no sound on the digital inputs - plugged DVD
player in as well as a CONCAST BOX via Optical Inpiuts that were
correctly configured. no sound coming out? is there a master volume
muting button? i do not have the original repote as well - using
Harmony remote. ideas? is this a fuse? transistors? blown amp, blown
dsp? who knows.

have you checked the speaker cables ?
Usually the Denon system has a problem with power regulators
if u have any knowledge in electronics i can guide u to repair it
if not .. u have to send it to service.
check for fuses if blown
power regulators mostly are damaged
and or power output transistor damaged
Good luck From Audio-adviser.com
check speaker conections. disconnect all the speaker wires and use one speaker that you know that works and connect it to each channel one at a time. most surround sound stereos will not go into surround mode unless all the speakers are connected so make sure stereo is in 2 channel mode to start testing. check all fuses sometimes amp fuse is seperate from power circuit and denon uses relays in 99% of thier units.
connect your right speaker cable to the left output, if the sound comes out then the problem is on the left speaker ( the cable or the speaker itself ), but if still no sound, then the problem is on the power output of the unit, need to repair them
Your receiver is going into protection. The first thing to do is disconnect all speakers at the receiver. Unplug the power cord, then let it set for 30 seconds. Plug it back in and power it on. If it stays on, you have either a wire shorting out at the back of the receiver, something that has pierced the speaker wire en-route to the speaker, a wire touching the other at the speaker or a blown speaker.
Speaker wires should only be trimmed about 1/2" bare at the terminal and make sure you twist the braid so it does not fray. Then connect speakers one at a time, testing the receiver power each time until it either shorts and cuts out, or, you have solved the problem. Hope this helps.

Is it possible for you to lower the source level? if yes go ahead...
There is an automatic Dialogue normalisation function in Denon which is activated to reduce overly bright input signals. ( most movies have wide variation in sound levels and therefore this function is avaialble). (see page45 of your user manual).
When your system worked fine with the AVR 2808CI, then why is it giving problem with AVR 3808CI....???? You must ask Denon.
Protection circuits are activated when:
1). There is rise of internal temperature.
2).Core wires of the speakers are touching each other or a core wire is sticking out of the terminal and touching the set's rear panel or the speaker itself has a problem.
3). Speakers with an impedance other than specified are being used.
4). the set is damamged or has bad solder / dry solder connection .
If your AVR is new, please do not accept, the set could be faulty. The protection circuits should not be activated unless any of the above happen.
You must know, at times the protection circuits are not fast enough and it could burn some of the transistors on the power output circuit. With time, the solders on the circuit board could give way and give you problems later on.
You must sort out with Denon if the AVR is under warranty.
try to introduce your speaker one by one and check every time you enter the speaker check for bad cable(internel short)open cable cover and touching of adjacent cables together.-try to change the position of your speakers.
