I have a sony str-dg820. In movie mode, when you turn the volume up, the display says ''protector'' and the reciever turns itself off. The volume level is still low when it does this. Also, I get no volume until the level reaches 10-11 on the display. It does not turn itself off when the setting is in 2 channel stereo. Please help!
You most likey have a wire short on your center or rear surround speakers. The wire short will be between the + and - points of the speaker wire.
To find the problem speaker, disconnect one of the 3 speakers at a time from the back of the sony and see if the problem goes away. Once you identified the offending speaker, check both the sony side and speaker side for the short. The small wire strands are hard to see and it only takes one to trip the protection mode, so look carefully.

check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair
Try disconnecting everything (all inputs, outputs and speakers, make sure there is no cable plugged into your unit except the power cord), turn it on, if it still shows the protect message, you have an internal short or a burnt out component inside the unit, possibly a desoldered contact on one of the connectors which generates internal noise of such intensity that it sends the unit into the protect mode.
If, after trying the above mentioned, there's no message, some other possibilities are:
- a bad speaker or speaker cable
- a bad signal interconnection cable
- a fault in any of the other units connected to your reciever/amplifier
Its internal problem of receiver and as you said, its brand new so it would have warranty cover.
Simply return it and get replacement.
I have all tech info including schematics of this particular model and can guide you to resolve this problem but I receommend to askSony for warranty replacement.
Reduce the volume level. IMPORTANT: If
the receiver is played back at maximum volume level it may enter the
protect mode. Maximum volume listening will cause the receiver to run
very hot and may drain the output capacitors.
Disable the surround sound option if both the A and B speakers are being used simultaneously.
Ensure the top of the receiver has proper ventilation to keep it from overheating.
If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some
receivers provide compatibility with the higher sampling frequencies
through alternate connections. Consult the owners manual for specific
Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
