I feel your pain!
I actually have an active thread talking about this same problem here. (Although it is the center channel that drops out on me... not the surrounds)
Intersting that you have the DE845... I have the DB840.
Most responses on the Forums have been suggesting that I have a speaker or wire problem.
Also, I wouldn't expect to get anywhere with Sony. I had a local authorized Sony repair shop check it out a few months ago only to find "no problem." After getting my receiver back, the problem was still there.
I broke down and sent my receiver into Sony about a month ago, and after calling customer service every business day for the past week or so, they have finally told me that they can "find no problem" and that I should "check my speakers and wires."
I suspect that, given others have had the same problem with these receivers, that it is some sort of physical problem with the receiver that isn't on their radar and is hard to detect.
It's a MADDENING problem to say the least, due to the intermittant nature of the problem...



This, needless to say, will be my LAST Sony product, ever.
All of that said, keep me updated on your progress.
One thing you might try is your local authorized Sony repair shop (if you have one in your neck of the woods). If your guy can figure out a fix, I would be willing to ship my receiver to him for the fix! (If I ever get it back from Sony, that is...)

My Sony is doing the exact same thing and it affects the center and rears. Using the 5.1 out from a DVD will not correct this issue as the sound will still not be produced from the bad chanels.
I spent 1/2 hour one night listening for where the clicking comes from and it is right inside of the case behind the center and rear speaker connections. I opened the case and found 4 blue small boxes which I assume are the relays mentioned above. I didn't try too hard but it seems like these are perminately affixed and not DIY friendly, although I am no electrician...just my uneducated opinion.
My 'homebrew' remedy for a while was to tap on the back of the case with my finger near the speaker connections. this enabled all the speakers for a while but the issues came back once again. This, of course, is not a perminent fix
Oddly enough, if I tapped around where the A B selector is on the front of the case the sound would come back for a short time as well. You can also try the fist/pound method as opposed to the tapping but at your own risk.Anyone have diagrams or mechanical manuals for these recievers?
I do plan on getting a new reciever soon but would like to fix this one instead of chucking it.
Interesting...
Can you see where the relays are soldered to the board?
One of the theories one of my HT friends had about this problem was that there was bad solder connections on the board somewhere causing the problem.
This would explain why my problem would happen at first, but then go away after the unit had heated up.
The crazy thing is that the problem seemly can't be replicated in the shop. I had a local authorized Sony guy look at mine AND I sent the unit to Sony and neither place could replicate the problem!
That's why I'm thinking that there IS a problem with the unit, but it could be that it's just MORE sensitive to wiring issues.
Thus, when I get my unit back (supposedly in the next day or so), I'm replacing all of my wiring to my mains and will see if that remedies the problem.
Although I wasn't ready to upgrade my receiver just yet, I will say that it is DEFINITLY next on the list, and Sony is totally eliminated from the list!

Other problems can be the relays themselves coming unsoldered. This is a common problem among all manufacturers as the receivers age. You might be able to get at them by removing the lower shield without removing the circuit board.
Another problem seen has been on the front panel where the 2 or three circuit boards connect to each other with some connectors. These can also have solder connections break down. This alters the data going to the digital processing board causing it to change decode modes.
On the digital board the three pin regulator IC's can also develop bad solder connections. Caution should be exercised if you attempt to work on this board.
Extreme caution needs to be taken around the power supply filters. The stored charge can weld a screwdriver to the case.

The 845 is not too hard to work on since it has an access panel on the bottom. If you can find a smaller service company, this is a fairly simple repair. It might make more sense to spend $35 - $45 on repairing this unit than $200+ on a replacement. I have an 835 that works fine in my home theater environment.
Have you checked and re-checked ALL of the places where you have speaker wires terminating?... i.e. wall plates, speaker terminals, receiver terminals...
The reason I ask is becuase I finally figured out that my problem was a TINY bit of the negative wire touching the positive terminal of one of my surrounds on the in-wall side of my wall plate behind my receiver.
Since I corrected that, the clicking and "protect" mode problem have gone away.
I'm not sure what kind of connectors you have (bananna, clip, pin, bare wire, etc.), but if you check everything and there seems to be no problem, you may even try re-stripping all of your wire ends where you have connections.
It is possible that you have some oxidation/corrosion of the exposed copper that is causing the problem. It may not seem like much, but it just seems to me that these 3-4 year old Sony receivers are VERY sensitive to any sort of wiring problem/issue.
Good luck!

Several electronic circuits in the receiver rely on the metal chassis for their ground connections. The circuit board mounting screws provide this ground by pressing the board down on the frame. If they work loose or become corroded then the circuits do not work correctly and this has been known to cause the relay clicking problem in the past on various receivers.
As someone said earlier, it may just be time to bite the bullet and get a new receiver.
Consider it a lesson learned on the build quality of the lower-to-mid range Sonys.
As I mentioned earlier in this thread, I was having the same problem as you and although the clicking would go away for certain periods of time, it ALWAYS returned.
I went ahead and just decided it was time for a new reciever, and went with the Pioneer VSX-1015TX.
I paid basically the same as what I paid for my Sony DB840 three years ago (~$400) and the Pioneer is better then that Sony in every possible way. It has the Pioneer MCACC auto-calibration (which is quite nice) and it is THX-certified.
What I would recommend is do some research and find yourself a new receiver. Avoid Sony -- check out Pioneer, Harmon Kardon, Yamaha, or Onkyo.

Re: Sony STR-DE845 Reciever making clicking noises
i was having the same issues and was wondering if anyone ever found a solution? Did anyone else try touching up the solder? did that work? what about replacing the relays?Re: Sony STR-DE845 Reciever making clicking noises
Ironic that I found this ancient thread about the same time as Casey. I've been using a Sony DB930 for years with no problems whatsoever. Now...no rear channels at all, and the center channel comes and goes with no rhyme or reason. I am disappointed beyond consolation. There have some interesting posts in this thread regarding relays, solder joints, and grounds.Old posters, new posters! Is this repairable, or am I saddled with an unaffordable option and an inferior product. (Not to say that all channels operating makes it inferior. It's just that the 930 is so cool).

Re: Sony STR-DE845 Reciever making clicking noises
Hi Greg,Yes there is hope, just like fixing a Ferrari really. It just takes some patience and puzzling :-)
The bottom cover comes off easily. Test for a while with the receiver upside down, tap the board lightly with the plastic end of a screw driver. If the sound comes in and out then you have reproduced the problem.
Now disconnect the power cord. Using a good/strong magnifying glass look at the solder joints on the board. If you see a second concentric circle inside the outer one then you have a cracked joint. On my board I re-soldered about 15 of these, finally got the one that caused the problem.
Reconnect the power cord, turn on receiver and gently tap again in same areas as before. If the sound stays on, then you got it. If still clicking look more closely at the joints. Be gentle of course, banging the board will create new problems :-).
In my case the L and R main speakers would cut off, center would work. My specific issues was in about the center of the main board.
I previously fixed cracked joints on the power switch as well. This receiver works well for me. Even with HDMI on my display I have no desire to spend $ on a new receiver so I fix as needed.

So from what I understand from HTF this is your first post and you used it to answer my query. I am eternally indebted. I have a couple days off next week and will attempt your suggestions. I'm no expert with a solder iron so if I see myself getting in too deep I'll call in the pro at Southwest Electronics (Danville, IN). Thanks again for your thoughtful response.
