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.

I have fixed 3 shorts on my de845. 2 have been caused by cracked solder joints. they were speaker cutout problems...yours most likely is the center channel relay on the main board. take the thing apart. you need to get to the back of the main board and re-flo those solder joints. get your geeky pc buddy and do it together(buy him a sixer). its really not that hard...just a bunch of screws. disconnect everything from the main board including the front plate. be careful with the ribbon cable...mine is hurting at this point. not meant to be removed so many times. put it in straight. my leads bent, but was able to straighten them. there are 5 relays together, one for each channel. they are white cubes and prb a little smaller than the tip of your finger. its the 4 leads on each of these that you want to take a soldering iron to . i'm not sure which ones the center channel so do them all in that area. it may be hard for you to tell which leads they are so just go overboard and at least get everything in the vacinity. i did all component leads because who's to say another's not ready to go bad. you've gone this far. touch the heated up tip to all the leads at the very end of the barb. you can reflow the solder without actually touching it. the metal lead will get hot enough. hold it until the solder liquifies, then let it cool. do this on a flat surface. my other fix once was a re-seating at the speaker switch a,b,a+b on the front plate. there are 2 boards plugged together there. i bent the leads slightly so they seated in more tightly. if your left or right front goes out, sometimes thats an easy fix...try b if you're using a, or the opposite. don't forget the speaker cables. if you're using both zones then you prb already figured out you need to re-flo! test and cross your fingers. good luck.

I had the same problem with the right channel. It turned out to be a broken wire inside the receiver; it can be found connecting from the main PCB to the card for the 5.1 board. After repairing the broken wire, it has worked fine. The harness connects the 5.1 low level signals to the board which are then redistributed to the amplifier section. It is a bundle of wires in gray casing and with red, black and white wires (with shielding). Find the offending wire, repair or replace and it should be fixed. Hope this helps

I had this problem last night.
To solve it, you can reset the amp by:
1) Put the receiver on stand-by
2) Hold down "MODE" button and press on button
3) "S.F. CLR" appears in the display and surround is back on.
