Protection Code 11 on 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.
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.
Thank you!

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.

SOURCE: Sony STR-DE845 center channel cut out, receiver clicks

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.

Error code 11 protector unit has no speakers

My only suggestion on the above information would be to reset the receiver. You can do this by first turning off the receiver. Once the receiver is off, hold the Power On button down for 5 - 10 seconds. This will reset everything to the factory settings.

Protection code 11

Here is the link to the user manual if you need it;®ion_id=1 Check page 54 for details of the error message - it should disappear if the speakers are connected properly and the unit is switched off and on. Check page 17 for speaker connection details, and ensure they are all correct. Check page 19 for details of the factory reset/memory clearing. Hopefully this will clear the error code and let you set the unit up. Hope this helps, please ask again if no luck :)

I'm getting Protector Code 11 on mySony STR DA3000ES receiver and then shuts off. How do I fix this?

Could be a fault in your speakers or speaker cabling triggereing a protection circuit or something deeper, which is not user serviceable. Try different cables and different speakers (loan from a friend or something). If your problem still persists, take it into your nearest dealer/service center
Best of luck

There is a defect in the final amplification stage of the receiver. This may have been caused by a short in the speaker wires. The typical defective parts are the output transistors. Expect a parts cost in the $40 range for this repair. Any audio service shop should be able to repair this.
