Customer Question

I have a tereo component systen that is getting no sound when using the CD component. I believe it is how I have the setup on the Denon receiver. No sure how to proceed to check. Thanks. XXXXXElaine-mod41095.9176104514

 



Already Tried:
I have tried different buttons on the receiver, but I believe I have made it worse. The system has worked fine for years. It is a Denon receiver. Thanks.

LOAJ3256 :

Hello - maybe I can help. Can you please tell me what cables you are using and the make and model of your CD player and the model of the Denon .
Please advise and thank you for your time.

Hi,

Customer :

It is a Denon DRA 397 and a /sony CDP - /ce375. Cables are xhi. There are a lot of buttons on the receiver regarding zones, etc. I really think someone tried to turn on the system and pressed one of the wrong ones. I have tried to correct by going through the buttons, but nothing seems to work. The system worked fine until just a few weeks ago, when utilizing the normal turn on process, I go nothing. Thanks for your help.

LOAJ3256 :

Hello -- can you hear AM/FM at all? Is it connected to TV? Can you make sure: The system display does NOT say "Pure Direct", the Zone is set to #1 , and IF your Receiver has TAPE MON that it is OFF... Please advise and thank you for your time.

Customer :

Thanks. I set the zone to "main". The pure direct button is off. I still have no sound. When I turn the mode to tuner, I still get no sound. The only other thing mentioned is a tape monitor switch. I do not find one on the receiver. Please let me know what else I can try. Thanks again for helping me work through this.

LOAJ3256 :

Ok , lets verify that 1) The power does turn "on" and STAY "on" , 2) The "Speaker Selector" switch is on the correct set of speakers - verify that the speaker button is pushed in 3) Do you have headphones to test? Please advise and thank you for your time

O.K. I believe we are getting closer to an answer with your diagnosis questions. I did plug in some headphones to the receiver and did get music from the cd player. I tried both buttons (1 and 2) on the receiver and still did not get sound. The power button stays green for about 5 minutes and then turns to red for off. Hope this helps. I really do appreciate what you are doing. Thanks.

LOAJ3256 :

Thank you, helps a lot). Since the 397 will work with headphones, this *may* be a speaker problem, as when the unit goes "red" this is "protection" built into the 397 that self monitors the speakers / wires for shorting and excessive loads , such as a single or multiple blown speakers. Please

LOAJ3256 :
There are 3 types of protection that will commonly occur with the receivers. This is designed to protect the unit from permanent damage.
1) Thermal Protect = When the unit overheats this will occur, usually if there is not enough air space above and around the unit. There cannot be anything directly on top of the unit and there must be at least 4 inches of airspace above the unit.
2) Overload Protect = Most commonly occurs when a strand or more of copper speaker wire is not securely connected to the speaker terminal and is touching the chassis of the receiver. If the volume is turned higher than 85% this may also occur. If you need to turn the volume higher than this point to get the level you want, you need a more powerful amp.
3) DC Protect = When an amplifier fails this will occur. This will protect dc current from damaging the speakers. When this happens the unit will need to be serviced.
LOAJ3256 :

Can you please UN PLUG , disconnect ALL speakers and then plug in and turn back on and tell me if the SAMEthing happens? Also please check for "wire frays", or strands of the speaker wires touching each other, even a small strand will cause this as well. You may have a blown speaker, bad wire , or an internal problem if this test does not correct the problem, and would require a professional repair and this will be a test to determine what next steps need to be taken.

Please advise and thank you for your time.

Hi,


 


With your help I was able to pinpoint the issue as the receiver. I tried an old marantz that I had and the sound came through to the speakers perfectly. It actually sounded good. Thanks again.
