Onkyo TX-SR702 in PROTECT MODE -- how to reset?

All,

I shorted speaker wires I was hooking up. Now the receiver turns on only for long enough to display "PROTECT" before turning off.

the red "standy" light is lit when it is off.

How can I reset it?

Thanks.

REgards,
Chas.

SOURCE: stuck in protect mode

i believe protect mode is because you have the wrong impedence speakers, they are too low (4 ohm? 6 ohm?) it chols work with 8 ohm speakers

SOURCE: problem with onkyo tx 919 unit

Hi...
If you've had it "fixed" 3 times and the problem comes back either you have the wrong impedance (ohms) speakers connected or the power supply in the unit is the actual problem.

Happy new years,

Scott

SOURCE: My Onkyo TX-SR500 receiver stays in standy/on mode.

It may be your amplifier protection circuitry is being activated and shutting down automatically. This is usually caused by a faulty output transistor in one or more of the channels. I recently repaired my Onkyo TX-SR500 which had this problem.
Using a multimeter on ohms check between C and E on each of the ten output transistors. I found Q6051 and Q6061 to be short cct on all pins. Once you have located the faulty channels check the adjacent components for open or short cct.

I replaced the following components,
Q6051 (2SD1047)
Q6061 (2SB817)
R6091 (2.2ohm fusible)
R6081 (2.2ohm fusible)
R6101 2x 0.22ohm 2W
Q6031 (2SD2061)

The amplifier now works perfectly, cost of the parts is about $15-$20.
If you don't feel confident doing this yourself just find a friend or tech who can do it for you.

My Onkyo tx-ds595 reciever turns on but after 5 seconds it goes into protect mode. I really would like to fix this porblem myself. Please help.


This can be caused by shorted speakers or speaker wiring, disconnect all the speakers and see if the problem goes away.

My receiver is in protect mode..what does that mean


See reasons for protect mode on onkyo site.
Most likely the speaker wires are shorting or are reverse polarity. see connection diagram.

Hi, after i turn the power on and then press the stand-by button, it clicks off to stand-by mode instantly. This is an Onkyo TX-SR500


This indicates that the system is going into protect mode. First disconnect all speaker wires (with the power cable disconnected). Then turn the unit on and see if it sill shuts aff ofter a few seconds. If it does not, then you have a problem with the speakers or speaker wires. inspect the wires at both ends for frayed strands that may touch. If that all lookd good, plu the speakers in, one at a time, until the problem reappears. Be sure to turn the sytem off before plugging in any speaker just to prevent any accidental short which could be catastrophic. If the system goes into protect mode with all speakers disconnected, you probably have a shorted output transistor.

My onkyo receiver say protect


If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

Onkyo TX-SR702 remote problem


So what you're saying is you think the receiver is broken because the remote won't turn it on.

Try fresh batteries or another remote that can be programmed for the Onkyo and get back to us.

I just hooked up my old Onkyo TX-8511 receiver to my bose speakers, which is also hooked up to a subwolfer. When I turn the volume up the system goes into protect mode. Any solutions.


Just check your speaker cabling again. Make sure that all of them are seated properly, none is touching each other or the body of receiver. Rewire if necessary..
Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny wire touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough and it could blown a few trasistors in the power circuit.

Otherwise, do your bose speakers play out load on other systems?

No sound


The unit is in protect mode until then. What needs to be determined is why it takes that long for the system to settle down. Basically, there are circuits built in to prevent faults from causing damage to external devices like speakers. These circuits prevent the output section from turning on until all of these voltages are correct. If you recall from a long time ago, it was common for the speakers to produce a loud pop when the receiver was first turned on. These circuits prevent that (as one example).

This unit should be brought to a service shop as it will require signal tracing to determine the faulty component. This is not likely to be diagnosed remotely through a forum like this.

Good luck and keep us posted.
