Dts will not lock denon avr-3300

Are you sure that model is HDMI v1.4 compliant? I know my Denon 8508 is not so I use optical outs to get 5.1 surround sound.

I understand, it's something I've misunderstood on my denon avr-790 as well when connected to a samsung 8000 series led tv.
The answer isn't in the receiver's settings (you can be on whatever source you want on the receiver end when toggling the menu). You need to toggle through the tv's sources to find the menu (usually found on hdmi 1). I've spent towards an hour recently troubleshooting only to find that it was the tv's source that wasn't set properly and I was trying to change the receiver's settings instead of the tv's source.
Hope that helps!

The best audio for any source will always come digitally from the first device in which it appears. The Cable Box would be that device.

Hi,

First make sure that your remote control is set to "Amp" as it can control many different devices.

Then make sure that you have connected the Monitor Out socket on the receiver to your TV.

Next make sure your TV is set to show the picture from the input you connected to the Denon monitor out.

Now press set-up button on the remote and the System Setup menu should appear on your TV.

If this helps then please rate my answer,

Many thanks,

Chris

TV's are not your best source of audio. Get the TV-related audio digitally from the source, NOT the TV.

Does this help?

I have some Denon components myself and had some problems. Ask them here, and within a day you should have solution for this problem.

Probably you have to reset the device to factory settings.

kindly check digital settings on your dvdplayer. The output should be in digital domain. Are u using original dts audiocd or burn dts audiocd.

WHAT TYPE OF AUDIO CONNECTION IS USED FRON THE SAT TO THE DENON? IT HAS BEEN MY EXPERIENCE THAT YOU MUST CHECK THE OUT PUT FORMAT OF THE SAT OR EVEN USE A COAXIAL OR OPTICAL CABLE AND ON THE FRONT OF THE DENON PRESS THE INPUT MODE BUTTON TO DISPLAY AUTO

OK.....there was a strange thing with this receiver......make sure that you are not on " headphones only ". Had a customer with the same problem. As for the fan, it doesnt run constantly. It only runs when the amp is hot enought to require extra cooling.....HOWEVER....there was a problem with the fans on these units, so much so, that Denon released a modification for the 3300 including a new fan and some upgraded circuitry.

If the unit is not flasning " protection ", or " overload".....you should be OK., however I would spend a few bucks and get the fan mod installed.....these are good sounding units and ecen though it does not have Dolby PL II, and DTS-ES, I have owned a couple of them and find that they sound better than most new ones. Get out your owners manual and look in the headphone section. If memory serves me well, there is even a way to do it with the remote. Good luck.... Rob
