Question about Sony STR-DA3000ES Receiver
Reinstalled this receiver and it went into Protection Code 11 so checked to find that the center channel speaker wire wasn't secure and had crossed the positive over to the negative terminal. Followed the manual instructions after securing it properly but to get the same results. Took it to the local Sony authorized repair site to be told that the RIGHT CHANNEL (not center channel) amplifier was blown and needed to be repaired for an estimated $438. (it cost $90 to find this out). So now it's a shelf warmer. The speaker wires for all the other channels had been secure and okay. How they found the right channel to be the problem was a mystery. All channels had been working fine prior to my reinstalling into a new tv stand.
MY QUESTION IS THIS:
Even if they were deceiving (the repair shop) it would cost too much to find out. So.........what I really want help on is this:
I could make very good use of this if I could at least disconnect the right channel amplifier (or all of them if necessary) and just use this receiver as a preamp processor by using the preamp outs and connecting them to external amplifiers.
COULD SOMEONE PLEASE GUIDE ME AS TO HOW TO SPECIFICALLY DO THIS ?

SOURCE: fix my receiver
Disconnect the power cord.
If you're using banana plugs, check that the cables are tight on BOTH ends. If you're using the binding posts then make sure that not a single strand of copper has gone astray. Any peice of it that can come into contact with the receiver in any place other than the speaker output terminals will cause this problem.
If you fix all of the above and still have the problem then it is possible that one of the binding posts has a reason for not making good contact. Disconnect all of the speaker wires and reconnect them to the other terminals, ie; instead of using terminals A, use B.

first turn the actual volume up on that channel on the reciver then make sure your speaker wires in the rear are using the same lenght each

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.
