Sounds like the output stage is shot.
Here are a few things to try. If there is an option in the manual to reset the unit to factory settings, try that.
If that doesn't work, disconnect all of the peripherals, and select the radio. If you get sound there, you may have a bad cable.

Beyond that I would say the amp needs repaired.

What's your problem?sony v444es 5,1 wont turn on, only clicks the relay on power board non stop


Sounds like your power transformer is bad. You might also check the power board for cracks. This model had a history of that.

Hi - I have a Sony V444ES receiver that I have four speakers on A (in house) and two on B (outside). I hooked up a third speaker (rock speaker) for outside use however the sound is very low compared to the...


What's a rock speaker? All you will hear with one speaker on the Rear Right output is the Rear Right channel which is typically for effects and ambience. You DO have a manual, right?

Individual speakers commonly have different responses given the same amplifier input. Where you physically place a speaker once it's electrically connected is up to you. Speakers placed outdoors might not have the sound-re-enforcement of nearby or adjacent walls as indoor speakers do so they will sound weaker.

Receiver str-v444es no sound on headphones or


discharge the output circuit! If you don't you will blow a 10 ohm resistor every time. I've worked on hundreds of these receivers I know. They need the output circuit soldered at the voltage driver ic's and quite possibly some capicitors replaced on the digital board. The caps mounted near the heat sinks dry up the fastest. These are nice amps. Larry's Electronics Sacramento Ca. ledstiles@hotmail.com

Got a humm noise when I turn receiver down,it does it on all functions what is it


Chances are it's the Large Electrolytic Capacitors in the power supply. As you have it on all functions. These are to filter out the 50/60HZ hum in the mains supply and so that's most likely what you are hearing!

Sony Receiver STR-V444ES and Blueray


You might have to go into the players setup and select the output and audio stream options. If it is set for PCM only it will not receive the Dolby or DTS signals if you selected them in the DVDs audio selection menu. There may also be a signal select in the Sony receiver to assign the digital inputs to selected units.

Hope this helps

Cheers
