Harman Kardon AVR 245 Receiver PROTECT Error Message/Shutting Down All Equipment

Hello-we'd really appreciate any help if someone happents to know anything about the following issue: we have a Harman Kardon AVR 245 Receiver, Refurbished but less than a year old, that has suddenly displayed a PROTECT error message that cuts out all stereo equipment. One of the JBL ceiling speakers is simultaneously making very odd, intermittent, crackling sounds emitting from only that speaker but AFTER all equipment has gone off.

For a Denon Receiver, someone had mentioned that a Protect message could be related to a crossed speaker connection, however we had had no issue whatsoever, all new Monster cable run and all new circuit breakers (22 installed throughout the home, where typical for this square footage would have been 10 circuits). We also had $20K in new electrical when this was just gutted, to ensure safe electrical.

Two things should be clear: no appliances or any other lighting was even on when this occurred AND that NO breaker was tripped at all. Second, all the equipment we believe went of simultaneously due to it being synched with a Logitech universal remote that ties everything together (i.e., Listen to Music, Watch TV, etc-for each action, all related equipment goes on or off together).

Does anyone know whether this might be related to the receiver itself, or to the wiring? Because of the extensive wiring and circuit work we had done before this install, we didn't think it could be the wiring but didn't know if this could be the Receiver itself. All speaker equipment and stereo equipment is top of the line. Has anyone heard of problems or faulty equipment with the Harman Kardon AVR 245 Receiver in terms of this Protect message? Thank you!

Could be your receiver only, it has tripped due to discrepancy on the output stage of your amp. that cracking sound in one of your speakers could have caused the trouble. it is possibly shorted. but in your case it could have damaged already the amp that;s why it would not turn on. normally it will first trip, turn on then turns off. but to stay off and not to turn on again is major problem of the amp. or maybe it emanated from miscabling, probably the ceiling speakers got connected to a high output or main amp. but try removing all speakers first then turn the unit on. see if it does power up.

HARMAN KARDON AVR 130NO SOUND FROM SUB WOOFER

The receiver must KNOW it has a sub and you must decide how bass is managed among all your speakers and set up relative levels.

Harman Kardon AVR 500 Only works in NON-Surff mode ?


This is a good indication that the surround processing section has a problem. This can be anything from a supply voltage being missing to a defective processing IC. Without testing inside the unit, it wil be difficult to determine. With surround procesing turned off, the entire section is bypassed. This is why standard stereo mode sounds OK. The static sound is digital noise and can be poor processing or a bad D/A converter IC.

Hope this helps,
Dan

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.
