The display reads "protect".so i


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

I have a Harman Kardon AVR 235 Receiver that go's into Protect


To avoid making the avr go into protect mode when you power up your Hafler 4000 that is connected in the avr's pre-out, you must power up the set up in the correct sequence.

1. Turn off your avr
2. Connect Hafler 4000 to the avr's pre-out it it is not yet connected
3. Turn on your Hafler 4000. The avr will not go into protect mode becasue of the transients from the Hafler because it is still not powered on.
4. Turn on you avr. There should be no more transients from the Hafler at this stage unless it is not functioning correctly, so the avr shouldno longer go into protect mode.

Protection mode.


Hi, protection mode means either the speaker terminals are shorted or the unit is overheated the manul says fix the short (DOH!) or unblock the vents (DOH!) but if it is really an issue with the microprocessor, then unplug the unit, hold in power and the tape loop buttons at same time and plug back in, wait 15 seconds or so until the display flases about once a second and then release both buttons. I will doublecheck these are the correct buttons, but I am pretty sure (I have the manual)

What failed component causes protection error message to display right at power up.


well, i just got this thing from a friend. its a Denon AVR-800. when powered up it displays the stops, just before finishing a -protect- shows up. There's a little red light standby light that blinks off and on also. i think that has to do with the internal problem. any suggestions?

Protection on display


disconnect everything from the unit and see if it still does it.
if it does i would check the output transistor (ic).

Receiver in Protection Mode


Electronics like a receiver are so sensitive to power surges. I'm sorry to say that it's most likely unrecoverable, especially if it wasn't plugged in to a surge protector. Even if it was, they don't all protect 100% from surges. :-/
