Question about Sony STR-DE945 Receiver

1 Answer

My Sony DE 945 Blue LED light indicating digital audio reception

The Blue LED no longer lights and the AFD decode feature no longer works. I still have the DVD player and the HD Sat receiver connected via Fiber Optic "Monster" cables and the sound works, but the auto decoding feature no longer works. Any ideas?

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?

Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

How can i get the dts sound field to work. Shouldn't it automatically switch to that sound field. I have a samsung bluray dvd that hooked up to it.  The dolby pro logic and pro logic 2 indicator...

If you are playing media that has both dolby digital audio and dts audio, your player and your receiver will decode the first audio codec listed first by default unless you select it otherwise yourself. If your remote or receiver has an A.F.D. (auto format decode) button, press it until your display shows that the sound source is dolby digital or DTS, whichever sound mode it was you wanted when you started your DVD.

I have a sony str-db940, since it came back from being repaired, it reports 'not in use' when the 'sur' button is pressed and won't decode surround sound. Any ideas?

Check if you're using the digital cables like optical cable to get the audio from the receiver. If yes, please select the Input mode to AUTO by pressing the mode button repeatedly. If you're using a analog cables, please try to change the sound field and check. Press the A.F.D button repeatedly to change the sound field and try. You can also try connecting a different audio source like Cable box, dvd player and check the issue.
If the issue persists, please reset the receiver. To reset the Receiver, turn OFF the unit and press n hold the MODE + button and Power button till S.F Initialize appears. If the issue still persists, you may be having 90 days warranty after the date of repair or original warranty which ever is longer. Contact sony to resolve the issue.

Sony STR de845, 5.1 Surround does not work. 3.2 is indicated o

3.2 IS the "5.1" mode for this receiver. 3.2 is indicating that you have 3 front channels and 2 rear channels. The ".1" is applied to all the speakers (LFE). If you read the manual on page 37, you'll see that "3.2" is displayed with either "Dolby Digital 3.2" or "DTS 3.2". The little icons of the speakers in the display window will show you which channels are active. The bottom line is as long as you see the blue light, it's decoding multi-channel discreet surround sound (at least 5.1).

Sony STR-DA5000ES 7.1 Receiver

its for digital decoding of the sound source. You need to connect a digital cable (ie optical) from the DVD player to the optical input in the receiver. The receiver should then decode the source into multichannel components ie 5 channels for example

Sony V555ES Amp:

Try setting your amp to "auto format decode".
It should easily be heard in this mode.
The sub will not show up on the display when in 5.1 mode. (Blue light on)
Use this with music, and use the 5.1 with movies to get a better experience from your amp.
The sub will work in 5.1 but doesn't show up in the display. Try movies with loud sounds.
Most of the pre-set sound fields are of no use to me. I only use normal surround, and AFD and love it. I hope this works for you!
