Most of the time it will need service (output transistors and resistors) This is a job for a electronic service tech. Estimate would be $100- $130

Hello Roy, If the unit is turning off when there is nothing connected to it then that means there is an internal hardware issue. This unit would have to go in for service. Thanks, FJD

When home theater is turn on, protector push power is flashed on thee screen. player will not function further. volume level is 9. currently can't be turn down.


Protector means there is a short circuit somewhere in either the speakers, the wiring or inside the unit itself....you can try disconnecting all the speakers and then turning on the unit...if the protector goes away, then you have a bad speaker or bad wiring to the speakers....if the problem stays, then there is a faulty circuit in the receiver itself and will need to be serviced

It flashes the word - protector


Hiya,
Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts (touching wires). If it cuts out, it needs to be serviced.
Regards
Mike

The word protector is displayed


If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

Speakers don't plug into inputs. Check your work.

Try powering it up with nothing attached, then proceed to attach things (like a speaker to the speaker terminals) and see what happens.

On 5.1 receivers, some inputs can be switched to Digital/Optical/Coaxial instead of Analog (RCA cables) - look for an Input Mode button. If this doesn't help, turn the unit off, then power it on. If you don't hear a click 3 to 7 seconds after turning it on, it may be in Protect mode, and simply be a coincedence that it failed after installing the new cables. This can be caused by several things, most of which require in-shop service.
