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.

Hi, it's most likely the contacts on one of the 4 black relays that is giving you the problem. Check out this forum for the fix. http://www.avsforum.com/avs-vb/showthread.php?t=1068233 Just open up the relays and clean off the contacts and you are good to go. Although it's not the same model of amp, it is most likely the source of your problems. Good luck

I have the STR-DE945 and recently the center channel started to cut out. Now all the channels cut out. Playing around with the ON/OFF switch seems to turn the speakers back on but they will cut out again after 15-30 minutes. Talking to Sony. Trying to find out if the switch can be replaced. Referring me to an authorized Sony repair center for more info. www.sony.com/repair- to find a service center by zip.

I own the same Receiver and am also experiencing the same exact symptom you describe. It started about a month ago and now is getting worse and worse. Sometimes if I give the receiver a little tap with my hand the center channel clicks back to life for a while. It's interesting that we are all experiencing the same issue. It is weird though. Some days it works okay, other times not at all. I have opened the case and blown out any accumulated dust with canned air. That seemed to help for a few days but now it is back. I am just going to plop down for a new receiver at this point (you can get a reciever now for half the price I paid for this with more features!) In the meantime I have a friend who is an engineer for Sony and he'll take a look at it.

I'm experiencing the same symptom. My center channel cuts out and the only way to get it back is to shut it off, unplug the unit for a couple of minutes and then plug it back in. Although that doesn't always work either. Mine started off like yours as well but has been getting progressively worse. I took it to Sony for servicing but they couldn't find anything wrong, it was behaving for them while it was there. It is an intermittent problem that will be hard to diagnose until the center channel goes completely and doesn't come back. My serial number is 4771435
