Question about Sony STR-DE945 Receiver

3 Answers

Stuck! My STR-DE945 clicked inside for some reason and then the whole thing doesn't play any audio. How do I switch it back internally because all the buttons do not fix this. My Receiver always clicks off when playing in stereo and only when I tap the top of the receiver, then it fixes the problem temporarily but then gets bad again. Any luck of maybe blocking the receiver of automatically cutting off its channels?

    I have the same problem. Seems like it is staying off an increasing amount of time.

    sooo, others have the same problem. It's like the buttons dis-engage or something. i'll be listening to something, then click, sound goes out until i re-press the dvd, or vid 1 button etc. not always a solution, and VERY annoying! Anyone have a quote on what it may take to fix tHis?

    Same problem.  My power button hasn't worked for quite some time, but just this month the audio started dropping out after a clicking noise in the receiver.  Tapping or lightly pressing the SPEAKERS selector turns the audio back on for an indefinite period of time.

    My parents are having the same issue with the sound not coming out. When they tap on the speaker switch the audio starts coming out again for a period of time but then they loose it again. I'm speculating that the speaker switch has gone bad. Problem is that I am 5 hours away from them so I can't get my hands on the reciever at the moment to look at it myself. I'm interested in any findings anyone else finds with this problem.

    I only use the remote on my stereo. So the power button doesn't seem to fit as the problem. The unit has a delayed start after power on this is normal and just as it starts there is this click. Now after a period of time, it gets hot and clicks out .... its like a capacitatior or something is shutting it down. Sometime off an on a couple of time and it's back. I took it into Best Buy and they say that Sony doesn't stock the replacement parts.... can't seem to tell me what they might be.... I too love this unit. I want it working again... 3 for auction on ebay now.... thinking hard.

I was able to fix this issue by opening up the receiver, removing the circuit board that the power button and speaker selector knob contact, and then reseating that board back onto the circuit board it was connected to (the one with the majority of the control buttons).  This completely resolved the problem.  The power button works again and the audio does not drop out anymore.

My STR-DE675 has the same problem, I've opened it up and narrowed it down to two audio relays that don't always engage like they should. For me it's the center speaker and the headphone relay. Tapping on them with a screwdriver makes them work again, so maybe this is why tapping on your receiver also worked. I think I will have to install a pair of new relays.

Ok guys I am with you on this same problem mine started with the power button on the receiver not working then it moved to this clicking sound that happens right before the sound goes out. The strange part is that the video still works so it is surely and audio problem. I will keep this page and post if I figure it out.

It's possible there are several bad solder joints on the front panel PC Board which can cause non responding controls, loss of sound. I repaired mine that way. Try turning it on with remote, see if that works.

Sony STR-DE945 Clicking Noise Sound Cutting Out

I had the same problem, I realized it was due to bad solder joints in the relays that physically turn the signal on and off to the speakers. There are relays for each speaker and a main relay for the mute/headphone. The click you hear is the relay disengaging. the relays look like narrow boxes about an inch high. If you open up the amplifier, try gently pushing on the top of the relays, if they click you know you have a bad solder joint. Remove the board, turn it upside down and re-solder the relays.

the following video shows what a relay is, and another problem can be that it is dirty, if so follow the instructions in the video to clean it.

STR-DE945 stuck in auto protect mode?. I'm pretty sure it is the output capacitors but I do not Know where they are located to change them.

First of all my STR-DE845 started having the protector problem about 6 months ago and I bought this receiver back in 2001. This is what I found wrong with mine. After searching online I found a service manual for the receiver, this came in handy when diagnosing the problem. The first obvious thing was discoloration of the board around the IC 501, 601, and 701 Op-amps. When looking at the receiver from the front these are the three vertical NEC ICs to the right of the main amplifiers. Even with no load these amps get very warm. Sony failed to add any heat sink to these ICs so eventually they can de-solder themselves, specifically the 701 IC which is the one closest to the back of the unit. With mine I was able to slightly push the 701 more vertical, since it was leaning, and I believe it has helped it make a better contact. The protector circuit will kick in if it senses the Op-amps are shorted or not making contact. The best solution is to add some copper heat sink to these ICs, they already have screw slots for a heat sink. If they ever fail you will have to get new op-amps and re-solder them to the board. Hope this helps.

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.
