Question about Sony STR-DE345 Receiver

1 Answer

My receiver powers on normally, and functions for a while. Then there is a "Clink" noise, and the speakers all go silent, but the receiver is still on. Any ideas?

    From OP: "Protect" does not come up on the screen, and it seems to happen not long after it is powered on. There is nothing obstructing cooling vents. Could internal dust be causing this? The speakers have come back on a couple of times, and sometimes come back when you give it a good whack.

Look for PROTECT icon or alert on display the clink is usually the internal breaker switching the unit off to protect from catastrophic failure due to overdriving or grounding, etc. Also make sure it is not over heating. make sure there are not a bunch of other components stacked over the vents on top , give it a space to get air to cool off during use. they do get hot and click off, THE SCREEN WILL STAY ON.

    Your outputs are on the way out, this is what happened to my first sony A/V unit. I would turn it on and it would work fine for a while then just go out, "whack" it & it would come back on and work for a while after about 3 months the thing went out completely. Took it to a shop where they told me it happens to these units all the time. They had 2 others on the shelf that they were using for spare parts because once the owners heard the replacement cost they just left them. Start shopping deals for a new one. Good Luck!! Thanks for the 3 thumbs!

Makes large thumping/chirping noise when turned on. Its not even connected to the receiver

Since you have said the speakers make this sound when "turned on", I'm going to assume there's some form of power amplifier attached (internal, external or otherwise). Based on the minimal information provided here, this simply sounds like the normal reaction of a speaker when the amplifier is turned on. In short, an audio speaker is a type of "transducer" and when power is applied (thru some form of amplifier), the cone reacts to the power surge and causes a thump, pop or other noise. Turn on your TV for example and you'll usually hear a small pop from the speakers...and a larger/more powerful amplifier is likely to make a louder noise. Without further information, in most cases this is quite normal.

Assuming there is an external power amplifier, my advice would be to turn the volume on the amp (regardless of whether there's a receiver connected) to 0 before turning the power on. If it still makes such a noise, it's possible the volume control of the amp may require cleaning.

Good Luck!

No audio coming from speakers. The receiver turns on, and there is a quick blare from the speakers, but then they go silent.

Is the BLARE a random noise or is it a program playing at maximum volume? THAT would stress the unit. Turn it down.

My C720BEE receiver is silent. Display window indicates everything is normal. But no signal is going to the speakers. No lights on front panel - indicating no connection to speakers A or B. Can anyone tell...

Please note if you are getting a clicking noise from the amp 4 seconds after switch on ( that is when the power light turns green from red ). If you are not-- it indicates an output short or failure and the protection circuit has not connected your speakers to prevent further damage.
You will have to get professional help to get it fixed.
One simple thing you can do is to disconnect all the speaker from the amp and turn it on and see if you hear the click- that would indicate that one of your speaker is damaged or shoerted, you can tryu it one by one.

Hello. I get no sound out of my AVR 7000 Receiver. No cables behind has been touched in the past. I'm trying TEST TONE, and everything seems normal in the display, but still no sound. I use Preout a NAD...

You don't say if all speakers are silent or just the ones to the unspecified NAD power amp. Do ANY speakers work regardless of which device powers them? Could the NAD be the problem?

My HKTS 7 Sub woofer makes no noise,the led burns from amber to blue as normal,and every so often i hear a low rumble noise. The Sub is powered and has 1 cable to the receiver, the fuse is also good.

Subwoofer is center speaker from A+B speaker signals. first check your wire to the receiver. Otherwise you need electronics service on the amplifier inside the speaker.

Behringer Truth B2031A powered monitor speaker - radio interference in left speaker

A well know problem to the Behringer Truth B2031A speakers is radio interference and noise. I had the same problem with mine and found a solution on a forum!

If you open the speakers, you'll see a cable from the main board that runs to the 2 lights at the front (on/limit LED's). It functions as an antenna... Disconnect it and your speakers are silent, finally. (OK no leds, but I can live with that).

Onkyo TX-DS 595 receiver surround channel unrealiable

How you power off the amp won't hurt it generally. I used to fix ONKYO amps under warranty, and I can tell you now, it will be full of dry solder joints. Take you unit to your local repairer, and they will resolder all the offending PCB's inside. This type of repair will fix 99% of strange audio noises and cutting in and out etc. for ONKYO recievers. Otherwise this is quite a good product.

Sound only comes out of left channel, only dvd player works

I would Initialize Unit back to factory settings by turning off main power switch then hold both 6.1/7.1 surround and direct buttons ( they are next to each other near main power switch) in while turning un main power switch. Hold both buttons until you see all lights light up. Then check functions and setup like you bought it new.
Owners manual also explains how to initialize receiver
