Yamaha RVX1500 is in protect mode????

According to you symptom, “when I press the power button, the display lights up for a second, then goes off with the clicking noise heard inside the amp.” it is due to overcurrent protection. Enter self diag mode to confirm. DO NOT switch on the amp for three times; otherwise your amp will be locked permanently.

Your unit is going into protect mode. This normally indicates that you have a bad channel. Make sure that your speaker wires are not shorted or touching anything other than the turminal and check your speakers as well.

Going into "protect mode", check for blown speakers or shorted speaker wires, sometimes even a source can be a problem(DVD,CD PLAYER,TAPE DECK,ETC.)
There is an electrical short present in your system somewhere, it can be the receiver has an internal short.
Disconnect all sources and speaker wires from the back of the receiver, then see if it still goes into "protect mode", if it does, then there is an internal short in receiver, if it doesn't, then one of the sources or the speakers or speaker wires may be the problem!
Goosd Luck !

As long as you're sure the power cord is firmly plugged in, it sounds like the protection circuitry of the unit has likely been activated. This happens when there is a short circuit in one of the connections. Check your speaker wiring connections and make sure all of them are firmly and carefully grounded (i.e. the copper of the wire touches nothing but the proper terminal, and that the wires do not touch each other). Check the connections on the speakers as well. If protection circuitry is the result of a shock or power surge (lightning, strong static, etc.), you can reset it. Turn it to standby mode, unplug it, wait for 30 seconds, then plug it back in.

This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Disconnect all the speaker wires at the receiver and turn it back on. If itdoesn't go into protect mode, your receiver is ok.

Reconnect the speakers one at a time being sure to turn the receiver off each time you connect a speaker and turn the receiver on until your receiver goes into protection mode again.

When it goes into protect mode again, the last speaker you connected has a problem. Trace the speaker's wire to the speaker looking for cuts or shorts along the way.

If you have a multimeter, switch itto ohms and check the speaker for a dead short, if you show a dead short you have a blownspeaker. Hope this helps.

p mean protection mode, something is not right to send the reciever into protect mode, check wiring

Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.

This is the protection circuitry. Mine is doing the same thing. I'm trying to get a schematic for it right now ;-)
