Question about Denon DRA-395 Receiver

Denon DRA 395 flashing red power light

I accidently shorted a speaker "B" positive wire with a speaker ground wire. After a pop the receiver shut down with the power light flashing red.

I unplugged power to the system and let all cool down for five minutes. When I re-powered the receiver went pack in to flashing red mode.

    Dennon AVR 788 keeps flashing red and will not stay "on". This has shut down entire system.

Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

When I connect my power and ground leads the amp turns on for about 3 seconds and the light goes red and it switchs to protect mode. The speaker and rca wires are disconnected


You have a faulty output device(s)... If there is NO LOAD, then you have an internal problem, the Amp "Thinks" it is sensing a "Short" and is shutting down, to "Protect" itself...

It's going into protection. Check your speaker wires at the receiver, make sure none of the braids from the + to - are touching. Then if you still have the problem, disconnect the wires at the speakers and test power. If your receiver still shuts down, disconnect the speaker wires at the receiver and test. If the problem persists, it is a problem in your receiver and it needs serviced. Hope this helps. If you need further help, post a comment and I will help you further.

On/standby Red light blinking can't turn on system


It's in protection. Disconnect all your speaker wires at the receiver then power it up. If it stays on, the receiver is ok and you need to check all wires and speakers for shorts. The easiest way is to reconnect one speaker at a time and test power until it shuts down, then disconnect the speaker wire at the speaker and test again. If it stays on, meter the speaker for shorts or bad voice coil. if it still shuts off, check your wire or replace. If the receiver's power still flashes with all speakers disconnected, it needs service or replaced. Before reconnecting your receiver after repair or replacement, check all wires and speakers 90% of the time, that's the cause. Hope this helps. If you still need help, post a comment and I can help you troubleshoot further.

When reciever is turned on, green light flashes and then the system turns off and the red light flashes


You have a short, either in the receiver or in a speaker wire. Disconnect all speakers at the receiver and turn it back on. If it stays on, reconnect speakers one by one and test by powering up the receiver. You will either find the short or fix the problem. If your receiver still shuts off with no speakers attatched, it needs to be serviced. Hope this helps

Amp is going out.


Have you tried replacing all of your fuses? If that does'nt work check your ground........ I would check all your connections also could be a connection shorting out causing your red light to come on.

Brand new avr588 receiver is turned on....is on for five seconds and then cuts off to standby


Hi donnie025,

I can't believe you haven't received an answer before now.

The red flashing light normally indicates that the protection circuit has been tripped. It can be caused by something as simple as a short in a speaker wire. Even if there is one strand of loose wire that makes contact with the back of the receiver, another wire, etc. it can cause a short. To protect itself the receiver will simply shut down.

1st. I would suggest disconnecting all the speaker wires from the back of the receiver. Then turn on the receiver (obviously you won't hear any sound) and see if the receiver does the same thing. If it does you should try disconnecting all of the source components (DVD player, Cable box etc.) and try again. If it still does it the receiver is bad and needs to be serviced or exchanged if you still can.

2nd. If the receiver stays on after you disconnect, then turn off the receiver and connect one speaker at a time, then power on the receiver at test it after connecting each speaker. This way if it suddenly shuts down after connecting a speaker you know which speaker or wire to check.

Let me know how it works out for you, I hope this helps if you haven't figured it out already.

SOUND CUTS OFF AT HIGH VOLUME AND POWER LIGHT FLASHED RED


You need to check the DC voltage across the power and ground terminals of the amp. If the voltage drops below ~11v when the amp shuts off, you need to check the power/ground wiring and fuses.

If the voltage remains above 11 volts, you may have a problem with the load on the amp (incorrect ohm load, shorted speaker, shorted speaker wires...).

Alpine car cd player has no volume


It's possible that you have a shorted speaker wire. If one of the speaker wires is pinched, grounded or shorted it will cause the deck's internal amplifier to shut down. The easiest way to check is with a multimeter's resistance function. Remove the CD player and unplug it. Set your multimeter for "resistance" or "continuity". Attach the black probe to chassis ground; you can use the black ground wire in the deck's harness, clean dash metal, or the outer ring of your cigarette lighter. Use the red probe to test each of the speaker outputs in the harness: white, gray, green and violet. If you find a speaker wire that shows any continuity with chassis ground, then that's the cause of the problem. A speaker with a damaged voice coil may also cause the deck to shut down. To test this, probe the positive and negative leads of each speaker and test the resistance between them. For example, to test the left front speaker you'd put the red probe on the white wire and the black probe on the white/black wire. Each speaker should read a minimum of 3 ohms of resistance. If you get a lower reading then it might be causing your problem. If you don't find a problem with any of the speaker wires, then chances are the deck's internal amplifier has failed.
