Question about Denon AVR-3802 Receiver

Left channel not working

My left speaker died and I am diagnosing the problem. I first sent a test tone thru successfully. Tried a different speaker, different speaker cable. Plugged right speaker into left input. Left channel still no good. Plugged left speaker into right inputs: it works. So except for the successful test tone, looks like the left speaker inputs on the receiver is dead. Switched to 'mono movie mode' so I can get sound from both speakers until I fix problem.
Is it most likely a board in the receiver? Dust? It's fairly new unit. Any suggestions?

    Hi,



    I have the same problem, My Denon 1356XP's front right channel is not producing any sound (not even the test tone), i checked the connections, changed the speaker wires but didn't work. I have bought this receiver just a week back.

Hi,

Thanks, yesterday i tried changing the speakers from right to left, the problem still remained on the speaker getting connected to the right channel. Later i pulled out the speaker wires from the reciver's end for the right channel, cut them and pulled out new strings from the insulation, twisted them and inserted, the speaker is working fine, though not 100% but close to left channel. I guess the problem was old strings in the wire which had got over twisted and were not parallel to each other.

regards
Swamy

The first thing I would check has already been done, the only other thing would be fuses. I am preety sure there is a protection fuse at ever channels output to protect against a dead short. I am sure you have already fixed this problem but I thought I would give it a try. Let me know what you found.

Yamaha rx 530 center channel cuts out


Thanks for all the suggestions guys.

I've tried using the balance for left and right speakers, and when the receiver is acting up with the right speaker having a low volume, I tried moving the balance all the way over to the right speaker. The right speaker volume will not increase in volume but the left speaker will decrease in volume.

Just to clarify, the center and the rear speakers are balanced. The issue only happens sometimes when I first power on the receiver I will have no center channel. If I leave everything alone for a few mins, the center channel will come on.

So it seems to me that something one the receiver is going. The question is, can anyone suggest a physical repair for the receiver for these symptoms?

Thanks

Yamaha RX-V365 Receiver when I hook up my center channel it is not audible at all. The R and L speakers work fine when they were located in the FRONT A and FRONT B terminals, but when I moved everything to...


With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

I think your driver might be outdated. Try getting a new one here. Also, you were listening to a disk in the computer? Well then perhaps the speaker lead from the DVD/CD player to the sound card internally is flipped? If sound works correctly from everything but disks that is probably it.

Hey ajn1n1 we need to fine where the tinnyness is coming from Lets do a test shall we,

hook up your voice matched polks to your front left and right speaker outputs on your amp to see how they sound as mains. if you hear tinny then its the speakers. sometimes speaker need to be broken in a bit.

hook up your main front left and right speakers to your rear outputs. if you hear the tinnyness then its the output of that channel on the amp or a setting. Newer amps let you change speaker sizes in the menu so that it can change over the crossover for that channel.

NO RESPONSE FROM YAMAHA YST-SW305/205


Hi Ron,

It sounds like the sub is not auto turning on, or has no audio output, and or the sub driver itself has failed. Do you have a multimeter, and we can diagnose the unit? :)

Cant connect rear speakers


Hey there Subaquakid, the nature of surround systems is to identify separate extra channels of information and send them to the right address, being the selected speaker. In order for the rear speakers to work they need to be sent a signal. The media which you are using may not have the rear channel encoded. therefore the rear speakers have nothing to announce. Please ensure your source cd has the suround feature encoded. Hope this helps. Good Luck!

Both left and right speakers play audio for right speaker


I think you mean the left channel is out but when you use test tone, the sound comes from left and right channels through the right channel speaker. If this is case, the switching IC is malfuncting. Unit needs service
