Sony STR-DE575 5.1 Channels Receiver I have power to everything but I am getting ZERO sound. Is this something that is fixable or do I just need to replace my receiver?

Contact any service technician. Its audio output circuit board need to be troubleshoot. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

cant use both hdmi and opti outs try sum setting in blue ray but u nee dto plug all blue ray dish directto samsung hdmi then 1 master digital out form tv to sterio digital i n ok tell samsung your output also

hi pawanh75,

thanks in advance for a very informative setup that you have.

Here are some of possible mods , only if you like and can DIY

( or have someone to help you )


• Using a 6 ohms impedance for an 8 ohm impedance amp clearly

denotes that it heats up the output stages.

(please forgive my very technical words)


• One way to lessen the heat is to install a blower .

Use a 220V blower on top of the receiver.

( air should be in going up direction ).


• Before I proceed further please indicate if having the speaker

connected and having a zero volume , and just letting the receiver

in an "On" state deliverately produce heat on the receiver, or just

when the volume is at medium to high level.


If it s running hot at zero level with speaker , please post.

If it is running hot even without speaker, post also


• It may also helps , if you have a powered subwoofer ( for the low's),

and set settings on your receiver to "small"


Let me know what you find to help you further.

No. Like most AVR's it only provides a Line Level output for an externally powered subwoofer. Get a separate amp for the sub.

This unit most likely has shorted output transistors. The unit is entering protect mode which will prevent further damage to the unit. Expect a parts cost in the $40 range for this repair.

There is no battery to replace to hold preset channels. The preset channels are held by a charged capacitor to maintain the nominal voltage level to the PLL (phase lock loop) tuner. The capacitor can only hold the charge for a few hours, and then it will slowly discharge - for like a short power outage.

It only works through DVD setting

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

If you do not here a click as soon as the power is turned on, (note you must be in a very quite environment no noise absolutely to hear this) then the amplifier has blown output transistors which are pushing DC current to the speakers.

have you adjusted your sound settings while in listening to the radio mode?
