Error code - protector

Sony stereo DA90ESG powers on but gives a 'protector' error. Any help?

  • goedp Apr 20, 2009

    I have the stereo completely dis-connected from all components - and get this error.

  • goedp Apr 20, 2009

    Still no luck. (there is a secondary clicking (relay) post power up. first click when the unit is powered on and energizing, and sencond click when the PROTECTOR error comes up.

    1) I've opened the cover and pulled the connecters off PCB that go to the outside speaker jacks. (still errors)

    2) Held down the DISPLAY and PANEL UP/DOWN and got the CLEAR message, but still get the error

    3) I suspect it to be in the power amp unit, but do not know how to troubleshoot the power transistors (NEP250)

Try disconnecting all the speakers from the back and turn the unit back on. If the "protector" display goes away, turn the unit back off and reconnect one speaker. Turn it back on and check for "protector". Repeat.

If you find that one of the speakers causes "protector" to appear, you either have a bad speaker cable or bad speaker. Try swapping each of those out to see what happens.

    If you have all of the speakers disconnected from the back of the unit, check to make sure there isn't anything (such as a strand of speaker wire) shorting the speaker connections. If not, the receiver may need repair.

    Have you tried turning off the receiver and unplugging it? Plug it back in after a few seconds and turn it on to see if Protector re-appears.

    Sorry if this doesn't help.

    One more thing to try... with everything disconnected.

    1. Turn off the receiver
    2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
    3. All Clear should appear on the screen.

    Let me know if this helps.

SOny DA90esg sound distord like it have a cold ? any ideas

Check your wiring. Sounds like your "out of phase" The easiest way to tell if this is the problem is to adjust the balance from left to right. all the way on either side should sound good, then move to the middle and it sounds dead. That's it. Find your speaker wire that has the + and the - reversed and switch. If this is not the fix, post a comment and I can help you dig some more. Hope this helps

MySony str-da5000es is showing error code 11 and shut off by itself after few seconds.check and disconnect all speakers, unplugged power from wall and still showing error 11. am missing something in here...

error code 11 (protector) - According to the manual, 11/PROTECTOR means, "Irregular current is output from the speakers. Turn of the receiver, check the speaker connection and turn on the power again." Most likely, a strand of speaker wire is shorted to the chassis at one of the speaker terminals.
Hope this helps !

Power protector on sony surround sound system

Power protect is an error message that some thing is wrong in your sound system and requires qualified tech.

Normally that error message appears when unit got problem in amplifier output section, either it is speaker problem or some output chip is fried.

Function Selector Bypasses Input Sources

Hopefully this post isn't too late... That receiver has the ability to disable certain inputs. The easiest thing to try is to do a factory reset.
1. Turn off the receiver
2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
3. All Clear should appear on the screen.

Unfortunately, this clears out all of the other settings on your unit. It should, however, re-enable the inputs.

Let me know if this helps!

sony DA90ESG I have a Sony Receiver DA90ESG i have it for a while and its one of the best receiver i ever come across. Never the less i was playing it the other day and i heard a pop in the front speakers i was using the MD moode witth regular audio cables. I notice some of the displaying light were dim like it was not getting enuff power. After i check the wires ect i turned it back on the display said ' OK ' It was ok for a while and then the other day i was playing it again and the sound went. The same display light was dim and the light on the volume went off but the display was up. I tried checkng the wires and everything seems to be ok. After i left it off for a while and turned it back on it played for a short time and then no sound. I saw an unusal display it reds ' AC-3 RF' when i put the recevier on tuner the sign comes of but still no sound. I turned it off again for a day and it start playing again but after 5 mins the sound went again and the same display comes up again AC-3 RF' Could you tell me if it some thing that iam not doing or should b doing, or should i give it out to be fixed. PS When the sound chips out and u try to open the lever it just go up and down repeatedly at a slow pace and wont close, but when the receiver starts to work the lever moves freely and closed itself. It seems like a power problem not sure but any help will be gratefull dont want to buy ny other recevier. Regards Desi Wilmot
