I need to set my Yamaha rx v371 back to the Dolby logic setting. How do I do this?

Check for a bad fuse inside the receiver.

You need a new receiver, that unit will only do Dolby Pro Logic and all 5 speakers will play but you have to use the composite audio cables(The red and white cables for audio) to get the audio into your receiver and the yellow is video which you can run thru the Yamaha as well if you want any on screen adjustments that unit may have and refer to your owners manual http://download.yamaha.com/api/asset/file/?language=en&site=usa.yamaha.com&asset_id=35288
Net unit make sure it as least 5.1 and you can get Dolby Atmos on a few select models but whatever you get make sure you can pass you video signal thru with HDMI cables or component at the least, a couple of years ago I went from the Yamaha R-V1300 to their RX-A3020 and couldn't be happier, the new one which is the Yamaha RX-A3040 has Dolby Atmos but whatever you get and you are only running it at Dolby 5.1 at least each speaker will be discreet unlike in the Dolby Pro Logic mode you will be running, and 5.1 means 3 speakers in the front and 2 in the back or on the rear sides, so that is your 5 the .1 refers to the subwoofer because it get a one tenth of the signal the rest of the speakers can do so 6.1 means 3 in the front and 3 in the bab plus the .1 subwoofer. My system will do 11.2 but I will be just happy with 7.2 but until I move into a house I run it at 5.1. godd luck and feel free to hit me up with any questions...

That unit give you the option for a second set of speakers ?

If so , connect to Output 2 ( or B) on the speakers connections and select Spkr 2 ( or B) from the front panel

The optical connection (SPDIF) doesn't have enough bandwidth to transfer DTS-HD audio. To use DTS-HD, you must connect the blue-ray player and receiver via HDMI cable.

Each DTS-HD audio track on blue-ray includes also "normal" DTS audio, which is probably used when you select PCM. Player decodes it and sends decoded (non-HD) audio via optical cable to receiver.

The problem can be the cable or speakers or RX-V463 or settings. Need to check one by one.
Set the RX-V on DTS or Dolby Digital
1) Check Cables - connect the 2 (surround) cables from RXV's Centre Out to Centre speaker. If the Centre speaker works, then cables are ok.
2) Check speakers - Connect each Surround speaker to RXV's Centre out. If it works Speakers are ok.
3) Check RXV - Set it on DTS or Dolby Digital
Connect RXV's surround out (one at a time) L and R to the Centre speaker. If there is no sound, the problem could be RXV's settings (I need to read the manual).

Hope this helps.

you can connect Yamaha YST SW800 at the back of your receiver

Hello,there is a chance that dolby digital isnt turned on on the dvd players audio settings, make sure in the dvd menu its not set to pcm.

Check the settings in the Motorola to make sure it's outputting Dolby Digital instead of PCM stereo.

Indicators on the receiver can tell you if you're receiving mutlichannel audio or not.
