We sold and installed two Denon DBP1611s back in mid 2011. The client has called to say that the power buttons are blinking on both units. I had him hold down the power button for ten seconds, sort of magically thinking that this might make a difference. It didn't.

I don't think he's unplugged the units, but that's an unacceptable "solution" as it's kinda hard for him to get out of the wheelchair, crawl around, then climb back up.

Have you seen this problem on this model? Are there solutions other than the trash can? Do you need more detail? I'm going there in a few hours and can check out other details you might know about.

Thanks in advance!

If it does require a power reboot, seems like an ideal candidate for a blue bolt conditioner. That would allow you, or the client, to reboot via ip.

Try holding Play and Skip Forward while you power the unit on. See if that reinitializes it.

This isn't in the manual, at least not with the word "initialize" or "reinitialize" or even "reset." Where did you read about that?

D&M Service Engineering.

It doesn't really matter how I got it, I've been a Denon rep/dealer/distributor for over 16 years.

The exact procedure requires that the unit power up and NO DISC reads on the florescent display. Press Play and Skip Forward simultaneously. "Initializing" shows on the display. "Initialized" and then "No Disc" will display when it's done.

Look at it this way: The unit is already bricked. Trying the init procedure for post mcom or PCB replacement won't hurt it.

You didn't know that Denon is just not something a CI should sell?


I'm surprised those things lasted as long as they did...

Rats. I tried to post while I was at the client's place a couple of hours ago.

Lowhz, I'm sorry. You seem almost offended that I was interested in knowing how you got that information.

So... The red light blinks and that's all the player does. With that in mind, I tried to follow the procedure.

Problem 1: you say "Try holding Play and Skip Forward while you power the unit on." The red light is blinking. It doesn't respond to the power button. Did you mean unplug it, then plug it in... which does not power it up when the player is working properly? How DOES one power it up?

Problem 2: I unplugged it, just in case that's what you meant. I plugged it back in and green and red alternated for about thirty seconds, then only red blinked on and off. I tried that again and only red blinked on and off. Red is still blinking on and off (it's been two hours)(it was two weeks before that).

I agree that Denon is not something a CI should sell. I assisted with the setup but did not make the sale.

Any other ideas?

A client's Marantz CD player [can't recall the model, but it's a 2011ish] that has started doing the same thing. The red status LED above the power switch "flutters" rapidly and the unit becomes completely unresponsive to button presses or IR.

The only fix I've found is to pull the IEC power cable from the backplane, press and hold the power/standby button [on the Marantz it's a soft button], then plug the IEC power cable back in, then release the power button.

This has "unbricked" the unit twice so far...Perhaps these two D&M devices share some common componentry...?

Mogul,
If a component requires a service call, or requires the client to pull the thing out and do all that other crap, that component has zero reason being in our client's systems. If it happens twice, even to the same customer, but never again, that's weird but acceptable.

Is this happening to anyone else?

Fred, I love you, man, but that is, easily, combining product, setup and programming time, a $500 expense. Seems to me there might be new BD players on the market for less than that. Granted, only the Denon actually looks like a high-class component of yesterday, but jeez, that's A LOT to make it work.

It appears now that it might work. However...


I took one of them from the client's house yesterday. I just got it out of the van. Weather is in the mid 90s outside so the unit is WARM but what the heck.

Plugged it in; alternate red and green blinked, ending in red blinking. Unplugged it, noticed that red blinked for a good twenty seconds with no power. Looks like it's got a beefy capacitor in the supply!

Plugging it back in again, red and green alternated, ending with solid green, model number, and NO DISC display.

Lowhz's procedure did absolutely nothing, which makes me ask again, but slightly differently:

Lowhz, what is the goal of the procedure you listed? And for what model(s)?


But if I should not expect the procedure to work, I should know that so that I don't think something is wrong if it does nothing.

Edit: Just called Denon.

The tech I spoke with is wise. He didn't say this happens all the time and he didn't say he's never heard of it, but he didn't say he's ever heard of it, either. Since it now looks like it's ready to play, I'll try it out and see what happens.

He thinks that it went into protection. Who knows? Maybe the new condos in downtown Pasadena have crap power; I've seen that in the business section of Beverly Hills, where two brownouts a day is normal.

The Denon tech also thinks that if it's working at my place, then the client's restart procedure should be to unplug it for 24 hours, then plug it in somewhere else... little help for my client who must use a walker. Maybe we can get him a little wagon for dragging the thing around... that shows how ridiculous this is. If that doesn't show it, how about the fact that he'll only find it not working at the exact moment when he wants to watch a Blu-ray?

Did anyone verify the electrical service at this location? Hot/neutral reversed, low voltage, lifted neutral.....

After the comment about brownouts every day, maybe you could try a basic battery backup? I use Minuteman for a lot of devices that I don't want to lose power and have had zero problems. One client was in their office writing a guest list for a wedding during a bad thunderstorm and at one point, lightning struck very close to their house, the power went out and he said, "Well, that just paid for itself".
