the red flashing LED is that the Device is in protection mode.
the internal power supply . +15 volts and -15 volts are defected you need to be replace it ... Regulators 7915 and 7815 .... these you should change , might also need to check capacitors .

Connect a lead from audio out on the TV then to the desired input on the amp. Then go to audio menu on TV then select external speakers.

Too expensive to repair. Don't waste your $. Craigs List has hundreds of these for well under 100 bucks. Get one mfged in Japan not China. Circa 2007 and earlier.

There can be belts in the tray just like in a CD player to control the moving of the tray. Once they get lose the tray can not finish it's cycle and if it can not the tray will reopen. There are limit switches in these units to tell the computer what state it is in. If these switches get dirty or become defective the signal to the controller will never know the tray is in. It needs professional service.

Hi
possibility of turning off
there are several cases.
1.short circuit on one or more of the speaker wires.
2.overload and over heat turns the protection on.
3.parts need to be re-soldered.
hope this helps

1) turn off the main power button (not the big LED stanby button)
2) press and hold "input mode" and "speakers" button simultaneously
3) press and hold the main power button for seconds, until display flashes.
4) release all those buttons. The AVR is already reset to factory mode.

Hello,

What is the model number of this receiver? It could be in Protection Mode. Is power button on the unit flashing red? If so, that's protection mode. It could be as simple as a speaker wire got crossed or cut but it could also be something internal.
Step 1: Label all wires plugged into the receiver so you know where to put them back.
Step 2: Unplug everything, including the power cable.
Step 3: Leave it unplugged for 10 minutes.
Step 4: Plug in *just the power cable*
Does it still click? If so, it's an internal component that's bad.
Does the clicking stop? If so, add one wire at a time, waiting 1 minute before plugging in another wire. Keep adding wires till the clicking comes back. Once the clicking comes back, unplug the last wire you plugged in. That wire has a problem. It could be the wire itself or the device connected to the wire. If it's a speaker wire, for example, it could be that the wire got chewed or cut, or it could be that the speaker got fried inside.

Sometimes it is a simply little microswitch or a switch that looks like 2 brass little small thin long somewhere on the side where can under or in the middle where the tray this switch should activate , this part can be simply broken or oxydated, that is a switch that recognized there is a cd loading and makes a autofocus to the laser to read the table of contents all thing also the moving of the laser in this action is timed.

Maybe this can celp

Joyce, Only if it has HDMI connection.

Denon Audio... | Answered on Feb 27, 2016 | 103 views


All you need is some speaker wire long enough to get to each of the speakers your running. Use larger gauge if your running big speakers hard and/or over longer distances. Otherwise a medium gauge (16) will do fine.
You'll also need all the cables required to connect external components.

voltage ha a large bearing on the wattage
electrical law is volts, amps ( watts) and resistance
check the voltage of the machine

a small amount of white lithium grease is usually what is on plastic mechanism parts.

I had the same problem with my subwoofer unit. I found the zener diode ZD3 was fried. The pic below shows the diode and its clearly tagged ZD3. You need a multimeter to check this before you order anything. This diode should only transmit power in one direction. Its size and spec is 18v .5w zener diode. (that's 1/2 w) It's very inexpensive and the whole repair took about an hour. This is from a Boston Acoustics subwoofer MCS 160
Ok..the procedure is easy.
1) unplug the unit and bring it to a well lit work area.
2) remove the panel from the back and locate the board that is held to the panel by 4 screws and has the ZD3 diode. The pic below shows the diode at the end of my test lead. Note the direction of this part and reinstall the new one in the same direction. Its a simple de-solder and re-solder project. I elevated the new diode about 1/8 " from the board with a small strip of copper. This acted as a heat sink during the soldering and elevated the part above the board to help it dissipate heat later when in use.
3) re-install the board and plug in all the connections.
4) this worked for me and I'm enjoying my sound system again!..good luck0482b949-8492-43a6-91df-0fb2f0e6888b.jpg
