Check the input mode on the reciever so that they are set for dual, rather than just digital or analog. It might be set for analog and your using a digital optical in cable. Also make sure DTS mode is turned off, unless your watching a DVD that is dts enabled.
It sounds to me like an audio enhancement filter is malfunctioning. The pure direct on / off is a sound filter to alter the sound performance of the receiver. There is a rare possibility that there is something wrong with one of your speakers- causing certain circuits in the receiver to malfunction. A way to check for this is to connect only one speaker and an audio source. test each channel first(without pure direct) by connecting the speaker to a channel and then disconnecting it, and connecting it to a different channel repetedly, until you have gone through all of the channels. If you really wanted to pinpoint such an anomaly, then you would need to do it with every speaker through all of the channels to make cetain that this is not the case. But then again this is not very likely.
I would personally just use the mode that seems to work, because something is obviously malfunctioning, or possibly burned out. And repairing it is most likely costly!
I hope that you can get something out of my answer! sorry! Good Luck!
Here are some things to check:
Is the loudness control turned off or set to a very low level? If the PURE DIRECT button is turned on with the LOUDNESS control level at 0, you won't hear anything.
Have you removed the jumpers from the PRE Out/MAIN IN jacks? If so, the unit will only perform as a power amplifier.
Is the CD DIRECT AMP turned on?
If so, the unit will only make sound if the PURE DIRECT button is on.
Check the CD DIRECT AMP and the PURE DIRECT buttons are both turned off. This should produce sounds. If ti doesn't, check that the A and B buttons are on for their speakers. Both can be on.
You can try this reset precedure below, but it sounds like you may have a DSP board problem. This is a new model of Denon, it should still be under Denon's warranrty, it has a 2 year warranty. If this does not help, you need to take it in to be serviced. If it is not under warranty, you will not like the cost of the repair. A new DSP board usualy cost about $300 and then you must pay for the labor. It is not cheap. This reset procedure has been know to work some minor miracles, lets hope it works one for you.
1. Switch off the unit.
2. Hold the following STANDARD button and DSP SIMULATION
button, and switch on the unit.
3. Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.
Note:If step 3 does not work, start over from step 1.
All user settings will be lost and this factory setting
will be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.
By now the person who asked this (eleanorr) has certainly solved her problem, but in case anyone else has this same question: It *is* on, as the color change on the Power button indicator light shows. Most likely, the receiver is fine; it's just that your front-panel display is off! 1. Check the DIMMER mode by pusing the buttom on the front panel -- it may be set to OFF. 2. Push the PURE DIRECT button on the front panel (or remote control)
-- it may be ON, which turns off almost all of the front-panel
display. (Alternately, change the AV source, which turns Pure Direct
I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.
