My Yamaha MX A5000 keeps going into protection mode. Why can that be happening and most importantly, how do i reset it

Protection mode keeps the receiver from frying the power supply when a power transistor fails. You cannot reset it. You have to replace the failed power transistors.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?

The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

My yamaha reciever has a power problem in that when i switch it on, it only goes on for a few seconds and thereafter goes off.

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.

Will not stay on

Your receiver is going into protection mode.
Need to know what type of reciever. In the self diagnostic mode there are code that will tell you why it is cutting off. If it is as you say you, as for the fall, you may just be able to reset it in diagnostic mode and everything will be fine. You can search for the service manual online. It will explain the diagnostics and the protection mode in detail.

Protect mode Kenwood KDC MP438U in dash reciever

Anytime there is a short circuit or your battery down low enough you will recieve this signal. If you press the little "reset button" using a small pin or screwdriver your unit should reboot without the "PROTECT" signal. If seeing this "PROTECT" sign is a result of jumping your car, this will fix it. If the signal persists, then there is still a short circuit and you need to check your connection with the battery. Most likely it is touching the chasis or some othere metal.

Auto protect

that is actually a sign that the reciever is bad. it usually means the amp is blown. Not in the sense that it wont work. But its overheating and thats where the problem lies. for this recieve it only costs 130 for the pcb board that goes bad. I know no one likes to hear that there stuff is broken. But when i worked for Square Trade i seen a few dozen of these units come through and it was always the amp which can still be serviced by yamaha. -Thanks Nate
