TX-SR800 circuitry protection activated

press and hold the 'tone control' and 'info' buttons and press power. This will release the protect. The first thing that show on the display will be the protect code to tell you why it shut down. If it turns right back off, then you most likely have a short in the amp that will need to be repaired.

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

If there is no apparent cause for the protection mode activating (such as shorted speakers, burning smell, blown fuses, lighting strike or mains power surges), reset the protection as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

Sounds like it is failing its self test so it won't try to power anything. First step would be to disconnect the speakers, turn the volume control all the way down, then power it up. If it comes up OK, then you've got a wiring issue or a short in one of the speakers. If it still doesn't come up OK, then there is an internal issue in the circuitry - most likely the power amp, any you'll need professional repair help.

something is wrong either in one of your speaker connections or in the unit itself unplug for awhile to reset.try it again.make sure all connections are correct and nothing is touching.if that does not work it will be the unit itself

Hi,

Appreciate the "Ask Me" and my compliments on the choice of an Onkyo TX-SR605.

Onkyos are not very common in my country. Often, they are imported from the US and since we follow US broadcasting standards, there would be no need for modifications particularly with the tuning steps.

To my knowledge, most manufacturers would be coming up with a single model but with:

• variations of the firmware to suit the region/country of intended use; or
• a service menu where the country/region of intended use is selectable; or
• jumpers/bridges in the logic circuitry.

Simply, this is similar to having the unit with a voltage selector at the back for 120, 220 and 240 or an auto volt 100~240.

As to your concern, pls check:

• if there is such a feature in the menu to change regional settings (the user manual may have this information);
• firmware update, but rather than select US, pls select one appropriate for India;
• a service manual where the logic circuitry would be shown and if there are movable jumpers/bridges for the selection of intended region/country (warranty may be void).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The problem is not with the inputs. This unit is in protect because a problem has been detected in the output section. Try disconnecting the speaker wires and turning it on. If the unit remains on, there is a short in one of the speaker wires. If the unit still shuts down, there is an internal problem that will require repair. It sounds like this is a new piece. If so, it should be covered under warranty.

Keep us posted,
Dan

The unit will not outside the us.We have a different scan freq.

Hi,your fears are confirmed... the protection circuit is self resetting, and is operating because the amp will most probably have blown that channel as a result of the speaker wire short. At the risk of doing more damage(in the workshop,we always soft start an amp with output problems to prevent more damage)you could take the lid off, check and replace any blown fuses, be sure to use the same rating and type. If the problem persists, or the fuses fail again, it needs some expert attention. Off to the repair shop.... Good luck, and thanks for checking with FixYa

Hold video1 and press speakers A button, it will say "clear" If the message protect appears again, then its service time.
