Question about Denon AVR-1803 Receiver

Power button won't shut off

My receiver power button wouldn't turn on last night, the little red stand by botton was on. It is connected to a power strip, so I turned it off and then back on-The receiver came on but now when you push the botton to turn it off-it won't go off-Any suggestions???? I turned the amp off to tighten the centre channel speaker leads. Tilting the unit over turned the power button ON and I caused a 'sparkie' from the positive terminal to the chassis. The two internal fuses are still intact but all I can get is the little red led on turn on. I cant get the unit to operate. After 24 hours it is still the same. I can detect no 'smokies' anywhere inside and there is no smell at all..

    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 .

    Look in the Owners manual for a Reinitialize procedure , Restores
    everything to Factory defaults. Usually consists of Holding a couple
    switches while turning on main power. All Lights Should light up to
    verify Initialization. Then setup unit like you just bought it.

I was playing my Yamaha RX-V995 last night and it got really hot and subsequently shut off. Now, when I press the Power/Standby button, it turns on for a second. And then turns off again. Is this an easy...

Well - you may have. BUT try this. Turn the volume all the way down, disconnect the speakers, and power it up. If it comes up OK, you've got a fried speaker (or bad wiring). If not - yep, you fried it.

Dead no power.. checked main fuse, worked fine last night, went to turn it on today and nothing. its a sx-316 not sx-315, I say this because it tells me this is not a valid model#, but sx316 is printed on...

Check the resistance of the primary on the main power transformer, (with power off) should be 1-3 ohms. If open you need a new transformer.

If good turn it on and check for ac voltage (120v) there.

I have a Denon receiver, had it for a couple years now and has worked perfectly. Last week I was watching a movie and all of a sudden my receiver shut off and it blinked a red ring of death. I let it rest...

Did you recently move any speakers around or any items near the speaker wire connections?
It sounds like you may have a speaker wire shorting which is causing the receiver to go into "auto protect" mode. Check all of the speaker wire connections on the back of the receiver and at all of the speakers to make sure the wires are not touching or close enough to possibly touch.

When I turn on my receiver, it automatically turns off and the power button flashes red. Prior to shut down, the receiver display notes "Tuner Ext. In" What's the problem? It has worked p

Protection circuit turns off the unit because of critical conditions- wrong power supply voltages or one of the power amplifier channels is bad. First, visual inspect the power amp board near the heat sink for burned resistors, test outputs for a short. If there are no problem you may try to turn the unit on and you have several second before it shuts down to check power supply voltages and power amp output voltages and bias, then ... Long story you'd better take it to a repair shop or repair at

No power

Cathie, What **** installed the dimmer? Sorry you said not to ask. No power and no stand-by light, it may need a stand-by power transformer or the main micro. If the stand-by light is on and the receiver clicks when you push the power button it may only need a fuse. Make sure you replace with a fast acting fuse of the same rating for current (amps). NOT WITH A SLOW BLOW FUSE!!! If it blows again there is somthing shorted and it needs service.

Power Button Flashing Red

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.

Power button won't shut off

First thing to do is unplug the reciver for 12 to 24 hours. Sounds like it needs to be reset.
