Sony STR-DN1050 Receiver - Need HELP!

  • My Sony STR-DN1050 flashes "Protector" and shuts off when the PS4 is running. Most trouble-shooting tips point to a bad connection with a speaker due to low impedance, but the receiver doesn't have a problem when I'm watching from cable box no matter what the volume level is. I'm using Polk Audio RM6751 speakers which have an input impedance of 8 Ohm. The receiver says the speaker impedance needs to be between 6-16 Ohm so that shouldn't be the issue.

    Is it possible the PS4 causing the "protector" shut down somehow?

    Possible overheating issue? Unlikely.

    The only other thing I can think of is if it were to overheat. However, There should be plenty of room for ventilation (see attached photo).

    I feel as though I can cross this possibility off because I have a fan on the receiver now, circulating air. When it just shut down again, I felt the receiver and it was barely warm...

    Please help!

  • I pulled up the Owner's Manual for the Sony STR-DN1050 and found the following when it flashes PROTECTOR:

    "The receiver will automatically turn off after a few seconds. Check the following:

    --There may be an electrical surge or power failure. Unplug the AC power cord (mains lead) and then plug in the cord again after 30 minutes.

    --The receiver is covered and the ventilation holes are blocked. Remove the object covering the ventilation holes of the receiver.

    --The impedance of the connected speakers is below the rated impedance range indicated on the back panel of the receiver. Reduce the volume level.

    --Unplug the AC power cord (mains lead) and let the receiver cool down for 30 minutes while performing the following troubleshooting:

    *Disconnect all of the speakers and subwoofer.

    *Check that the speaker wires are tightly twisted on both ends.

    *Connect the front speaker first, increase the volume level and operate the receiver for at least 30 minutes until it completely warms up. Then, connect each additional speaker one by one and test each additional speaker until you detect which speaker is causing the protection error.

    After checking the above items and fixing any problems, plug in the AC power cord (mains lead) and turn on the receiver. If the problem persists, consult your nearest Sony dealer."

    If that still doesn't help, I would recommend contacting Sony directly at 800-222-7669.

    Anyone else have any suggestions?
