Re: yamaha rx-v1500 no surround sound
Do you have the owners manual of this Receiver. If yes, then I can guide you the page numbers:
The memory backup circuits prevent the stored data from being lost even if the unit is set in the standby mode, the power cord is disconnected from the AC outlet, or the power supply is temporarily cut. However, if the power cut is more that one week , the parameter values will retun to the factory setting. If this happens, edit the parametets again.
Now you want to reset all parameters:
Use PARAM.INI ( see page 63)
First put the MEMORY GUARD to OFF position.
To go to the the above :
Make sure the OSD is displayed.
Set AMP/SOURCE/TV to AMP,
then press MENU to enter SET MENU
Reach Option mode/2
enter C) PARAM.INI
All the parameters where changes have been made from their original setting would be marked in Asterisk(*).
Make the changes required.
Hope this works for you.

I,m not familiar with the Yamaha but most receivers are set up the same way. In your setup menu are the speakers marked on in the display?. Your DVR needs to be transmitting in 5.1 to start with. If this is the case then make sure you select the correct audio function on the receiver.
1) Check to see if the screen says "EXT DECODER". If it does, press the EXT DECODER button again and this should fix the problem
2) Press input mode button until the display reads auto or digital. It may be set to analog.
I dont know your reciver but if it has a hdmi input plug ps3 into it and set audio on ps3 to pcm,this will give you digital surround eg multichannel,if not you must use a optical cable from ps3 to reciver and set ps3 audio to digital.
hope this helps.
This set is getting old and is in the Archives section of the Yamaha consumer guide area. But, you can still download the owners manual if you need one.
If it is going into protection mode even when there are no speakers connected OR when the sound level is very, very low or zero it is not good news.
Yes, unplugging the line cord will cause the protection system to reset itself. But, if it shuts itself off again soon after rebooting it is a sign of bad grease in the output stages -- in all probability.
Let me explain: The audio output transistors are mounted to a large heatsink which keeps them cool during operation. They are electrically isolated from touching the heatsink by an electrical insulating washer. But, in order to keep them cool and allow for good thermal conductivity of the heat generated by the output transistors the washers are treated with a heat conducting grease. Over time this grease will dry out and lose its heat conductivity ability allowing the temperature of the transistors to rise; as the heat goes up they conduct more current and cause the protection system to activate and shut the set down (in order to avoid damage to the set).
That is the most common cause of your symptoms. However, there are several other possibilities, but I give this explanation a 90% probability based on my experience.
