The sound you describe is usually a mechanical noise from the transformer/case work. Home theater amps tend to have quite large transformer in what is, due mainly to its size, a rattly cabinet.

Over time, the lamination inside the transformer can loosen which could explain why it has only just started doing.

Alternatively, one assumes you moved the amp when connecting the new kit? This may have let the case work rest in a new way which is proving susceptible to relaying the vibration caused by the transformer as an audible noise on switch on.

This sounds to me as an issue not with your AVR but with your cable unit. I have seen this where there is a sample rate issue with the cable boxes. I would try to get another cable box, and see if the issue persists.

This unit needs to go out for service. There is an issue inside the circuitry in the unit.

too big a speaker load,unit sensors shut unit down when speaker impedance gets too low . and draws too much current at hi volume.A bad woofer or tweeter voice coil burned by sudden excess volume can cause this,also partially shorted speaker wires.

Yes it is fuse problem . Check the fuse whether it is blown . You can repair it with the help of service manual .

Had same problem with this reciever over the weekend. I had to hook up a TV to the COMPOSITE monitor jack and then I could see the menus. I could never get it to show the menu over the component outputs, however a DVD player hooked up played perfectly. Anyone have a solution?

Hmmmmm Sounds like one of 2 things....

1 Your DSP board is toast. ( not much hope, it must be sent to Denon as they do not have anymore entire circuit boards for swap-out replacement.

2. Heres the hope part......Inside your denon is like a computer.....there is a main board, separated by the big silver heatsink, and then there another main board. On the main board closest to the volume control, the DSP boards and Video boards plug into the main board . The DSP and video boards are up and down ( when the receiver is laying flat, like normally ), and they plug into the main board from the top.

Denon is NOTORIOUS for bad solder joints and the little white connectors that connect the "motherboard" to the DSP and Video boards are of suspect quality ( the rest of the unit is great )....So it COULD be that you have a bad solder joint on one of the connectors or the connector itself. There is also another set of connectors that joins the front panel display to this "motherboard".....these colder connections are also suspect.

I would have a denon repair shop look at it as I GUARANTEE they have seen this before.......best of luck...Rob

You may want to try putting an attenuater in the line with the RCA's to cut the input signal back just a little bit. So you are not driving the amp so hard with your preamp.

This is usually a heat problem. The more volume you ask of an amplifier, the greater the current (electrical) draw, the more current draw the more heat is generated. This is true of ALL electrical/electronic items.

As you describe it, the fuse is not blowing (stays on) so my choice would be a chip heating up and then shutting down. If that's the case (99% probabilty). The only other reason would be if the unit has an overload switch inside, it would react this way. Either way it's still a heat problem and truthfully nothing you can do.

Try this first though:

Is the Denon dusty inside? Dust can create 2 problems-heat and static electricity. Look through any vents you can get at. If the area around the unit is dusty chances are it is dusty inside. The best way to get the dust out is using a can of compressed air unless of course your vacum cleaner has a "blow" port.

In my shop, when heat is supected I use a can of freon th cool down chips, etc to isolate the component. This is not for a "layman" and strongly suggest bringing it into a shop.

One more question. If the unit using a knob for volume-do you hear a scrating noise when you hit the no volume zone? What happens if you go past the point quickly? I ask because sometimes there can be a bad spot on the volume. The volume knob is basically a circular resistor, whether digital or analog so this is a vague possibility (the other 1%).

If you e-mail me the serial number I can check with the Denon engineering department to see if there are any design problems as it may be a covered repair. It never hurts to ask.

Could be bad connection. Try to tight connection cables on receiver and TV. 

Check the batteries first. I have seen remotes that the lights will turn on when you press a button. It ended up being the batteries.

If the batteries are good, do any of the functions work?

Are you sure you have the unit in surround mode? It should say on the display MS if it is. If it is in the surround mode and you still do not get any sound to the subwoofer, make sure the speakers wires are all connected up properly. If all that looks good, you could have an amp problem. It shouldnt cost 100 bucks for an estimate. Contact the manufacturer, a number is located in the owners manual. Ask them if they have a factory service depot close by or what they charge to estimate or repair. Hope this helps. PS dont forget to rate this.

The Denon DRA-697CI stereo receiver typically uses a 250V, 2.5A fuse. However, it's always a good idea to consult the user manual or check the label near the power input on the device itself to confirm the exact fuse size and specifications for your particular model. Using the correct fuse size is important for safety and to prevent damage to the receiver. If you're unsure, you can also contact Denon customer support for assistance.

The Denon DRA-697CI is a stereo receiver. Typically, the fuse size for electronic devices like stereo receivers is listed in the device's manual or on a label near the power input. It's important to use the correct fuse size to ensure proper protection against electrical faults. Without specific information about the fuse size for the Denon DRA-697CI, I recommend consulting the device's manual or contacting Denon's customer support for accurate information. Using the wrong fuse size can potentially damage the device or pose a safety hazard, so it's crucial to verify the correct specifications.

Check and clean the dampening piston(s) associated with the raise / lower mechanism. The silicon oil may have dried up or leaked out.

More than likely the mosfets are shorted in the output stage.
