Question about Sony STR-DE697 Receiver

Channel cut out

Hi. Iseem to have a very common problem with a sony amp, where the centre channel cuts out after a few minutes. Have seen other posts (lots on the 5.1 sony systems) where users experience the same issue. Have checked the wiring and speaker connections, all seems fine. If the channel cuts out, a lights slap on the amp seems to fix it most of the times. Sometimes a second slap is required. Have had this occur when nothing is playing on the DVD, like when a movie is paused - you can hear the amp clicking. Have read people talk about cold soldering problems somewhere inside the amp - I don't feel comfortable fidling around inside the box.

    My 2001 suburban had its wiring harness cut. I figured it out eventually and thought I had installed properly. Works fine sitting still, but as soon as start moving, even just a few feet in reverse or forward it cuts in and out. So I thought I had a loose connector. Double checked and everything was fine. Disconnected the ignition power and determined its losing it from there even not connected to the radio. I checked with a volt meter. Could I have the wrong ignition wire? I've tested every wire there is for power with ignition on but only find its a solid green that gets power. Please help

Stereo Tech: Sounds like you definitly have a broken solder connection on the main PC board. A bad solder connection is tricky to find somtimes if one is not familiar with exactly what it looks like (kinda like mt st helens with a ring around the top) if you attempt this yourself DO NOT MAKE A SOLDER BRIDGE you will open pandoras box. Good luck

How do I connect a Sony xplod 1000 watt 2 channel amp to 1 10" dual 4 ohm voice coil 1500 watt planet audio subwoofer?


Connect one voice coil to one channel of the amp. Repeat with the other voice coil. Do not bridge the amp as your only choices would be series which would be an 8 ohm final load and cuts the amp power in half or parallel wiring which results in a 2 ohm load and very few Sony amps currently made can handle being bridged to a 2 ohm load.

B channel cuts off after a few minutes


Speaker is blown or amp channel is. Swap channel connections from a to b, etc, and test channel again. If it doesn't clip you have your answer. If it still clips out, your amp has a blown channel.

I have a sony str de-475 amplifier and the centre speaker stops working after about a minute. leave amp powered down for a while and it works again but only for about a minute


Try replacing the center speaker with one of the left or right speaker and run it for sometime ( do not connect the center speaker to any other channel ). If the system does not cut off the center speaker connection this way indicates a short in your center speaker.
But with the L/R speaker if the system still stops working you have a hardware problem and will need professional help to fix. 5.1 amps are complicated and difficult to access even for an experienced technician.

Got a Sony str-DE845 intermittently the front speakers on channel A cut out... B is fine for now. I'm guessing all relays are good just need to resolder a few areas but nothing looks bad. Should i check...


I have seen the audio relays cut out on these. Try tapping right on them lightly to isolate the problem . Andrews Electronics in santa clara will supply you the parts. Larry's electronics ledstiles@hotmail.com

The power on my denon av-1570 amp keeps on cutting out and the power light is red and flashing. I've looked at the troubleshooting section of the manual and it recommends I turn it off for a period letting...


If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

Sony STR-DE945 5.1 Channels Receiver


Hi, Happened across this forum looking for some remote info. Had a similar problem with my 945...main speaker outputs started to click off & on, no rhyme or reason. Found that the solder joints on the speaker output relays were cold (poor soldering). Actually happend twice, two different relays. Took me a while to find it, reflowed the solder, that solved the problem, over two years ago now. Are you able to dig into the receiver? Do you have a (good) soldering iron and some solder? If not take it to elec. shop and tell them to look for cold joints on the relays.

Front speaker channel cut off


I lean toward an overhating condition since the unit does not go into protection mode right away, and then returns.

My thoughts are as follows...

1) The receiver needs better ventilation

2) The speakers are below the rated minimum nominal impedance, causing the amplifier to strain and overheat

3) There is a problem within the amplifier that is causing this problem - this is not user repairable.

I'd try another pair of speakers which are rated at 8 ohm nominal impedance and give it a trial. At the same time, monitor the heat output from the unit (note that modern amplifier sections do run hot). If the unit runs extremely hot at a low volume and still shuts down on 8 ohm speakers, it's time for service or replacement depending on value.
