SOURCE: f61 error code

Sorry to hear about your error code F61

This code refers to a High Limit Temp. condition.
This is most likely caused by the cooling fan.
If the Fan has stopped running or not running at full speed, you will recv. this error message and the temp. reaches high-end limit.
Please check the cooling fan, any possible air flow restrictions and correct running RPM.

Hope this information has helped you.
Readers, please rate your technicians information.

SOURCE: Push Power Protector

As had already been stated by several people, the "Push Power Protector" scrolling marquee means that you have a short in one or more of your speaker wires. This is an easy problem to fix. First, trouble shoot which wire(s) has the short by unplugging all 6 speaker wires from the back of the unit. Then turn on the unit and switch the function to "Tuner FM." That way when you start plugging the wires back in, you will have sound (music) playing out of the speakers you plug back in, thus ensuring that that speaker wire doesn't have the "short." Now, with the unit on, start plugging in the wires one at a time in the following order...Green, Purple, Red, White, Grey and then Blue. Somewhere in that sequence, you will find that the unit shuts down and the scrolling marquee of "Push Power Protector" comes back on. Viola! You have your short. For me, it was the Grey wire because I had spliced it with additional wire to reach the back of my room and the splice was touching, thus creating the short. I placed a little more electrical tape on the splice to keep it separate and I am back in business! Good luck! :)

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.


Hello
Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

Tip

What "Protector" means


Quite often a receiver or amplifier will show the message "protection" or "protector". Other times, the unit will return to the standby mode and possibly blink the standby light. This is a protective mode that causes the shutdown of the unit to "protect" it from further damage.

Most modern electronics contain additional circuits that monitor the state of the unit. If a problem is detected, the unit is shutdown and a message of some type is displayed as detailed above. This is done to prevent further damage to either the unit itself or any external speakers or equipment.

Lets determine whether the problem is internal or external:
1) Disconnect any external equipment (speakers are the most common).
2) Power off the unit.
3) Turn it on again (this will reset the protection circuit)

If the protection message clears, the external equipment is the likely cause. Crossed speaker wires is the most common cause. If the unit continues to display the protection message, then the problem is internal and the unit will require service.

The most common internal cause is a failure of the output transistors. These can be easily replaces by an experienced service tech. Some units have complete amplifier sections contained within amp-pacs or large ICs often called STKs. They are so called because the generic part numbers for tehm are often STK-xxx. Panasonic uses large ICs with part numbers that start with SVI as well. If you are experienced with audio repair, a simple check of the transistors and the voltage regulators within the same circuit can often reveal teh cause of the problems.

Hope this helps,

Dan

Push Power Protector?


This indicates that you have a blown output amplifier or shorted speaker wire. Disconnect all the speaker wires and try to turn it on once more. If it shows the same display give it to a service center for repair.

HI:
Usually receivers go into overload due to a bad speaker make sure you disconnect the speakers also to make sure its overloading from a bad speaker. If the unit still shows overload even with all speakers disconnected, then your main amplifier output has a short usually a shorted output transistor is the cause. Unplug the speakers one at a time to and turn the unit on after disconnecting one of the speakers , to determine which speaker is at fault.

Its displaying push power n protector on my av system


Unhook all speakers to the unit and then turn it on...see if the problem goes away. If it does, then one of the speakers may be damaged...If not, then the amplifier circuitry has some sort of problem, possibly the output transistors/IC's are defective...If it is the latter you will need a technician to troubleshoot the amplifier to find out what the extent of damage is

The real problem is already informed you by the unit itself.
For us technician it was obvious that you have a faulty output I.C.
Your unit automatically shuts off to avoid further damaged most especially to the speakers.

I've advice you to look for a qualified technician/service center to replaced the output I.C.
After that your unit will back to normal again........
