    I've had the problem on 2 separate units now (the DPR 2005 model). The original experienced a power surge and I thought that was the cause. Now the 2nd unit I purchased work perfectly the first 24 hours and then with no cause or change in anything - it just turned itself off and now won't stay on for more than 2 seconds. PLEASE HELP WITH ADVICE!

    Same problem—I turn it on and it immediately goes into 'protect' mode before i can change any of the settings.  worked just fine for 2 years.

Cant get speakers to work


Normally I see most of the Onkyo units have game inputs for a/v. I am sure you have connected them to the right inputs. The output to the speakers, let's say you have external speakers, depends on the listening modes. You may want to go to the modes and go up/down through them to see if ;you can get audio that way. If your not successful you could run your game to the tv and the run the TV output L/R audio back to the receiver. That should send all TV audio to the receiver.

Denon avr789 shuts down when we try to increase the volume above say above20 is there a reason for this


The amplifier goes to the protect mode as there is heavy drain in the outputs- the MOSFETS.
This can be due to fault in the input signal, a poor DC regulation or a faulty speaker.
Disconnect all speakers and test one by one to confirm. Also make sure that the input signal is good, try with another source . Test also with the different input selection on the amp so as to confirm if the pre- amp is faulty.
Sometimes faulty capacitor in the sub power can give low regulated output and thus on load can shut down . finally check the input supply voltage, it should be correct or on load it can shut the amp.

Can't open,in protect mode


Hi:
First disconnect all speakers from the unit and then try turning the unit on too see if it still goes to protect mode. Protect mode is a shut down feature that shuts down the unit because of a shorted speaker or speaker wires are touching each other. If the unit does not shut down after disconnecting all speakers then reconnect them one at a time while turing the unit on after each conncection until you find the shorted speaker. If it shuts down with no speakers attached to it then you have a internal problem with the amplifier section, probably a shorted output transistor in the Amp circuit or preamp circuit.

Sony STR-DE475 receiver ''protect'' problem


The relay or relays that click disconnect the receiver from the speaker terminals so that no dc voltage can burn out the speakers. More than likely the power output transistor(s) are faulty. Look at the relay(s), determine the input and output connections. The inputs come from the output power transistor and emitter resistors area, the output of the relay(s) connect to the speaker terminals. Check for dc voltage on the input contacts in the range of 30-60 volts possibly. If dc voltage is found there then you have bad outputs, caps or emitter resistors. A word of caution -troubleshooting at this level requires advance knowlege of electronics, do not attempt this with out onsite help from a experience tech.

Look at inside at capacitor and fuse but they seem ok. again once i turn it on, it would automatically shuts off after a second.


When a system shuts down after a few seconds it is the self protect circuit shutting down power to the outputs to prevent (further) damage. It may be caused by frayed speaker wires, bad speaker voice coils, or blown output transistors. First, turn off power and remove all speaker wires from the receiver. Turn it back on and see if the problem remains. If it works OK, inspect each speaker wire at both ends for loose strands and correct these. Then, hook up your speakers one at a time until the problem reappears. That speaker or its' wiring is your problem. For safety's sake. turn the receiver off before connecting each speaker. An accidental short of the output terminals can be disastrous (and expensive).

SONY STR-DE125 READS PROTECTED


protection is designed to protect the output transistors from, shorted speaker wires, shorted speakers, too low speaker impediance,make sure the amp is well ventilated.
turn the amp off for 1 to 2 hours to allow thermal reset if this fails most likley some internal damage has occured and the unit will need to be serviced

Reciever shuts off


Hi there

May I ask how many watts can your reciever handle ? And how many watts does your speakers need in order to be powered up (input). The two speakers you have installed might be too powerful for your reciever to handle. You might have to down grade to less powered speakers. All in all you have an excellent product there good choice...

Stereo goes into protect mode


Protect is a safety feature so that you do not blow your speakers. However with it hooked up with the computer you may have surpassed the max output. If it still does this with out going through the computer, it has been damaged.

Unit going into protection mode


You should first have or check the impedance and resistance of the speakers. then if all the speakers and wiring checks good, the only way to tell if this unit is good or the output section has no problems, is to hook up load resistors to where the speakers go, insert 400 to 1000 hz @.775MV into an input, hook up an osilliscope to the load resistors and slowly turn up the volume and see if the waveform clips before it shuts down. I doubt if you will have the equipment to preform these test but a good repair shop will be able to help you out. If it does not clip or go out then its all speaker wiring and/or the speakers.
