Question about Denon Audio Players & Recorders
New Denon AVR-E400 runs very hot. After playing Pandora for a few hours on both Zones 1 and 2 at a moderate volume, it shut down. Box was very hot. Let it rest about 10 minutes and turned on again and shut off again 15 minutes later. It seems like it is running too hot and the receiver goes into protect mode and shuts itself off. The receiver is sitting on top of an entertainment center with plenty of room on all sides to breathe. This problem NEVER occurred on my old Denon AVR-888 with exact same inputs and speaker setup. Beyond this problem, I love the receiver. Waiting for Denon to call back after I explained to them the situation. Any thoughts?
I had a similar problem with my Denon receiver... I thought there might be some issue with the power source, which was a (supposedly good quality, surge protected) power strip that it was sharing with a lot of other gear.
I unplugged it from the power strip, and ran an extension cord from the next room and plugged it into that.
The switching off & on seems to have stopped.

SOURCE: Denon AVR-1803 shuts down
I am a Tech in Michigan and have worked on lots and Lots of Denon AV Receivers. These units have Protection circuits for Overcurrent, Dc Protect, 15v Regulator inbalance, Rail Voltage Inbalance, Low Ac Voltage, Low Standby Voltage and Thermal Protection just to name the ones I remember. My guess is you Probably have either Poor Intermittent solder connections or Amp is not Ventillating Properly. Make sure you leave room above Receiver to Vent and You are using no Less then 6 ohm speaker Impedance per ch. Refer to Speaker Impedance chart on back panel . [email protected]

SOURCE: Shutdown protection? HELP please
All of the Denon recievers I have repaired (over 100) that shut down after a very short time are going into protect mode. The display lights up and after about 10 seconds the display goes out and the standby led blinks red.
I have found that they have one of 3 possible problems and they all require that the reciever be taken apart and fixed at component level. No way to tell what your problem is until it gets put on a bench and troubleshot.
Problem 1. This is the most common problem. One of the front channels shorts out. On the big heat sink the front channels are at each end. It is the front left channel (close to the display) This requires that the output transistors be replaced as well as some driver transistors and some resistors and a capacitor. Lots of work for a blown channel. Denon has put out a bullitin to upgrade the bias transistor and change a couple of resistors to help compensate for this failure. That channel overheats more than any other channel.
Problem 2. There is a resistor that is right next to the preamp board that opens up. It is a 10 ohm 1 watt resistor and when it opens, it causes the unit to go into protect.
Problem 3. The +12 volt regulator fails. It is in the power supply area on a smal heat sink right next to the -12 volt regulator. Generic part number is KIA7812 It also causes the unit to go into protect.
Most decent repair shops can fix these from about $120 up to about $200. Depending on which problem it is and how fast they are at finding the problem. Most charge labor by the hour.

Normally when this happens it is because the impedence load is too small. This unit requires 8 Ohm speakers. If you connect 4 Ohm speakers, it will work, but work harder and generate excessive heat. If the heat is too much, the unit will enter protect mode and shut down. Once it cools off, it will work again. In your case, if the speakers are the correct impedence, check for crossed wires. If that is the problem, running the unit at higher volume levels should cause it to shutdown sooner.
Keep us posted,

Very important you have run system set up menu it configures your receiver with inputs analog or digital,speaker size,input,room correction etc Different input modes can be selected for the different input sources.
The selected input modes for the separate input sources are stored in
q AUTO (auto mode)
In this mode, the types of signals being input to the digital and
analog input jacks for the selected input source are detected and
the program in the AVR-3300’s surround decoder is selected
automatically upon playback. This mode can be selected for all
input sources other than PHONO, MD/TAPE and TUNER.
The presence or absence of digital signals is detected, the signals
input to the digital input jacks are identified and decoding and
playback are performed automatically in DTS, Dolby Digital or PCM
(2 channel stereo) format. If no digital signal is being input, the
analog input jacks are selected.
w PCM (exclusive PCM signal playback mode)
Decoding and playback are only performed when PCM signals are
e DTS (exclusive DTS signal playback mode)
Decoding and playback are only performed when DTS signals are
r ANALOG (exclusive analog audio signal playback mode)
The signals input to the analog input jacks are decoded and played.
t EXT. IN (external decoder input jack selection mode)
The signals being input to the external decoder input jacks are
played without passing through the surround circuitry Your remote is searching for inputs because you did not properly run system set up!!! Here is a link to your manual [PDF] AVR-3300/1 3.3E*
