Question about Sony STR-DE625
I am suddenly getting low / muffled sound on all speakers except for Center and Rear Right. The rest of the speakers sound very low even when the volume is at Max. The two "working" speakers sound fine. I've hooked up the speakers and wires to different jacks and have concluded that it's not the speakers or the wires. Moving them around, they sound fine on the center or rear right channels. I've reset to factory settings, changed levels etc, to no avail.
The only way your surround sound will work is if you have either the coaxial or fiber optic digital hookups attached to a PS3/Blueray/DVD/Cable box/Satellite box that have digital sound outputs. If you are just using the 1970's version of the red/white audio cables that is stero only.

There's a button that turns the speakers OFF right above the headphone jack.
Get the manual: retrevo.com

Testimonial: "@dunnbiker Very true on assumptions! I've tried everything the manual suggests. Right now, nothing is connected to the unit, but upon power up, I get the SP:OFF display (which is not seen in the DEMO mode). I will try the headphone jiggling idea and see what happens."
First off, you want to correctly isolate what or which channels are/is bad. Use one good known speaker. Connect that speaker, one channel at a time, and test that channel with a fixed volume level (don't adjust the volume when you check each channel). Isolate the low level channels and make note of it. Note: each channel has their own amplifier. Once you've isolated the bad channels, take it to a repair shop and tell them the bad channels. They will then locate the circuit and narrow down the search to fine the problem - it's usually a bad solder connection. If it blows fuses - more likely a shorted transistor. In your case it's a bad solder connection.

Tips for a great answer:
No sound or only a very low-level sound is heard from the rear speakers.
>>> Make sure the sound field function is on (press SOUND FIELD - MODE).
>>> Select a sound field containing the word "cinema" or "virtual" (see pages 28-30).
>>> Adjust the speaker volume (see page 19).
>>> Make sure the rear speaker size parameter is set to either SMALL or LARGE (see page 17).
