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?
Assuming you have the same Model Variant ( I'm not sure if Yamaha varies model from Country to Country) I just switch mine to effect off ( 2 Channel) to remove the surround component so that only A or B speaker pairs work.That should fix it unless I am mistaken.
Yes, sounds like your DSP chip has an issue. Not an inexpensive repair if that's the culpret. Around 400-500 to replace the chip. It's an awesome receiver and worth 300-400 in repair, however, a 3800 or 1800 can be had for 600-800 depending where you look. If you need more help, post a comment and I can help you some more.
Best thing to do is to put the unit in 5 channel or 7 channel mode. That will send left ch information to the front left and rear left speakers ( both will get the same information). Ditto with the right channel. The center channel will get centre channel information.
If all the speakers work, go out and rent TOP GUN. ( yes its old), BUT there are a few extreme scenes , one of which is the elevator scene, where the camera changes perspective and suddenly you hear the elevator doors close BEHIND you through only the surround speakers ( have the unit in surround mode....NOT 5 or 7 ch mode ). If this works ok, then you have no problems.
Remember, surround sound only produces information in the rear channels when the information is there. To check out the digital and DTS decoders, get an action flick. If you can, get a remote too, because that will unlock many features about the receiver that you cant get to with the front panel controls. Also go to yamaha and download the owners manual ( its free !!).....that should get you going.....
Why would you only hook up one speaker for the rear channel? in 7 channel stereo, all speakers have 100% signal sent to them as "stereo" in Dolby digital, rear speakers are for "effects" not dialog. like a plane flying past you or a car driving by, that's when you hear a rear speaker. It also needs to be placed behind you, not next to you or in front of you. Unless you are using zone 2 & 3 the receiver's surround back will work. if you only have left,right,center,sub & rear; the rear speakers should go to surround speakers not surround back. If you still have questions, post a comment and I can explain further. Hope this helps
I had the same problem. Set the reciever on 6 channel stereo. On this setting, you should be getting the same sound out of each speaker. Isolate which speakers aren't getting sound. Now, on your speaker switch (the A/B button), select A. If that doesn't fix it, select B. If that doesn't fix it, try A and B (if you can on your reciever).
Now, when you switch back to pro-logic, make sure your a/b channel switch is in the position that worked in 6 channel stereo. Yamaha recievers have a memory, and when you switch various modes, it makes auto adjustments based on what you had set in the past.
