I have a yamaha rx-v640 receiver. I am using it with a 5.1 yamaha surround speaker system. After I turn it on I start to hear pops and noise on the speakers as the receiver begins to heat. What can I do to correct this problem

I JUST EXPERIENCED THE SAME SITUATION HERE IS THE SOULTION YAMAHA SENT ME TO RESET THE SYSTEM HTR-5990 YAMAHA HTR-5990 FACTORY PRESET PROCEDURES All models require the STANDBY/ON button to be turned OFF to start the reset process. NOTE: The remote control cannot be used during the reset procedure. All necessary buttons to complete the reset process are located on the front panel of the receiver. This procedure is not intended to correct intermittent shut-off symptoms or problems MODEL: HTR-5990 (U.S.A. model/s) (BEFORE YOU CONTINUE, PLEASE READ THE ABOVE NOTES!) 1. Before you start this procedure, locate the MASTER ON/OFF button and the STRAIGHT/EFFECT button on the Front Panel of the unit. 2. MAKE SURE THAT YOUR RECEIVER’S MASTER ON/OFF HAS BEEN TURNED OFF. 3. With the Right Hand, press and hold the STRAIGHT/EFFECT button. With the Left Hand, press the MASTER ON/OFF button and HOLD both buttons for no more than “3” SECONDS, AT THE SAME TIME. SP IMP. * 8 MIN. will appear on the display, which indicates you are in the Diagnostics Mode. 4. Rotate the PROGRAM KNOB to the right (ONCE) until the display reads PRESET *CANCEL. 5. Press the STRAIGHT/EFFECT button (ONCE) and the display will change to PRESET RESET. 6. Turn the unit off by pressing the MASTER ON/OFF button. 7. Wait 5 seconds, then turn the unit on by pressing the MASTER ON/OFF button. You have now reset your component to the factory settings. NOTE: Yamaha receivers don’t have to be reset during normal operation. It is not recommended that you reset the receiver unless a setting has been changed that you are not aware of, or the receiver is not operating properly. The reset procedure will clear an incorrect setting that might be causing abnormal operation. GOOD LUCK

Hey, yeah that can be frustrating.

When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?

Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click.
after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers.
2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time.
If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date.
If they all fail, use a friends speaker and try it before sending it to a repair shop.

P.S. i found one on ebay i think you can get for under $100 bucks in the box.

SOURCE: The subwoofer is not working on our Bose 5.1 surround speakers.

First of all you should never indicate speakers as Large unless they can produce below 20Hz (which is very low), otherwise always set your speakers to Small.

Second, did you also indicate in teh setupmenu that you have a subwoofer? Because if all speakers are set to Large some receivers will omit a subwoofer because Large indicates the speakers can reproduce all sounds even below 20Hz.

So walk through your setup menu, say YES when the sub (SFW) is asked for and that should do the trick.

That receiver has A and B channels. Look for the Speaker button and press it until B appears on the diplay. The other room speakers will play the same thing as in the main room.
