Question about Denon AVR-3806 Receiver
When we play our music through the outside speakers the system will shut off. The power indicator light turns from green to red. The unit is hot to the touch. After a several minutes the system can be turned on again until it shuts off again. This occurs only when we are playing our exterior speakers. We have never had this happen while watching a movie or solely listening to music inside. Granted when we listen to outside music is is turned up louder. We have four speakers for the exterior. My initial inclination is that the unit overheats. Our electronics are in a closet with no or little air circulation.
How are your four outside speakers hooked up? If you have four speakers hooked up to only two output channels on the receiver, the receiver is sensing a short and shutting down to avoid damage to the amp.

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.
It's one of the power amplifier channels which has gone faulty.
I just found this out after having this problem with my AVR-1906.
I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).
I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.
Just waiting for them to arrive.
An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.
Hope thats of use!

Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.

It does that because there is a safety feature in all the newer devices. If your system is turned up to high you would blow your audio outputs or speakers. That's why it shuts off.

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.
