If there is no apparent cause for the protection mode activating (such as shorted speakers, burning smell, blown fuses, lighting strike or mains power surges), reset the protection as follows and see what happens.
Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.
Thanks a lot, I could reser the protection lock. Now I can slowly put all the cables and connectors and find out if there was any short circuit.

Make sure you have an analog RCA audio cable from the source to the receiver. Digital coaxial or optical will not work for zone 2 or zone 3. By adding an analog cable it will not affect your main zone, it will always go to digital first. Hope this helps

I suggest you run self diag. press [FM/AM] key + [Input mode] key and press the [power/standby] switch.
ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink
you'll likely have to measure the resistances of the output FETs to find a short,

Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.

Hi,
Can you be a little more specific about what the fault is and what you are trying to do? Is the machine constantly powering off?
The reset functions are in the ADVANCED SETUP menu which can be accessed by holding down the STRAIGHT button while you turn the power on.
If you can give more specific details about the problem, it will be easier to determine what might need to be reset - rather than resetting the whole unit.
