Question about Onkyo TX-SR601 Receiver

1 Answer

Programing Mode Backward

Recently couldn't get the receiver to shut down. I unplugged the unit to reset. When I plugged the unit back in, it switches on and off alright, but where my Plasma TV previously operated through the Video 1 selection on the receiver, it now has to be on DVD! I receive a message when selecting Video 1 stating no sync. no signal! When attempting to play a DVD in DVD mode, I get image, but no sound. A message appears stating that the Digital DTS signal is turned off. The DVD works fine in CD mode. Can you offer assistance?
Thanks, Rod

How do i reset avr-1705 denon amp?

Before you reset, are you doing this because the amp went in to some sort of protection mode?

Resetting will allow the amp to redo the self diagnosis. But if the problem remains then the amp will shut down again. Resetting doesn't fix things like bad wiring or blown output transistors. So only reset once you are sure you've checked through the system for any problems.

As a safety measure, disconnect your speakers before doing the reset. If the amp goes in to protection again then it is an indication that there are either shorted speaker outputs inside the unit.

Unplug the unit from AC power for 30 minutes, and disconnect all of the speakers and other associated equipment. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset.

If the unit starts up normally start connecting the speakers one at a time (shutting the power down before connecting each one), until one of the speakers causes the receiver to shut down. This speaker is faulty and would need to be replaced.

If the unit does not power up with NO speakers connected, then it needs the output transistors replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.

How do I reset a technics sa-gx350 receiver unit

Don't know that you can actually reset this unit like the new digital receivers. It does have protection circuitry that will shut the unit down in case speaker wires are shorted or if speaker impedance is less than the indicated rated impedance of the amp. do the following:
1. Turn off power and unplug from wall.
2. Check all connections and correct if needed.
3. Turn back on after 1-2 minutes.
If unit is still in protect mode you may want to unplug everything from the unit and then power back up to see if the problem is internal or external. If it powers up correctly then the problem is external. Power back down and plug in one external item at a time and power back up between connecting each item to see which item causes the receiver to go into protection mode.
If problem seems to be internal I'd recommend taking to an electronics repair shop if you aren't comfortable with taking apart to check fuses, terminations, etc. There may be a 5-amp fuse in the power plug head also.

I have a Sony STR-DE 597 reciever. I have been using it fine for a few years with no problems and it sounded great. I turn the unit on recently and a message was displayed on the unit that said PROTECT....

Protect will usually show up if the receiver was turned up too loud to the point where the speakers will crackle, the receiver will switch to protect to not damage anything. Unplug it for about 30 seconds and check all the audio wiring in the back to make sure everything is plugged in good and tight and no loose cables or stray pieces of copper audio wire and plug it back in.

My rxv 1800 wasnt used for probably a year but was left plugged to a wall outlet during that time it wasnt used. when i came home last week, i switched it on but immediately shuts off after a second. when...

r this one: Switc off your receiver using the main power button on the front face. Hold the the Effect button and the Direct button, and turn the main power ON.f it ain't working, try this one: Turn your receiver ON and, while holding down the [VCR1] button, press the [STANDBY/ON] button. "Clear" might appears on the display and your receiver might enter Standby mode.
Hope it does.. With your receiver in the Standby mode, hold on STRAIGHT (EFFECT) on the front panel and press STANDBY/ON.
* The ADVANCED sETUP menu appears in the front panel display.ress STRAIGHT (EFFECT) to select the desired setting.
RESET = To reset your receiver to its factory presets.
CANCEL = To cancel without making any changes Press STANDBY/ON to confirm your selection.
* If you selected "RESET", your receiver is reset to its factory presets and switches to Standby mode good luck

Onkyo TX-SR605 - Suddenly switches itself off and back on

HI, this is a reset procedure that this unit is trying to initiate. there has been a surge of some sort that the system has survived but, there is some lasting damage as well that has resulted in a slight programming error within the mother board.

This unit has a program that was installed at the manufacture. it runs the basic operations. there has been some major damage that is causing the internal program to stall and reset itself. the only way to reprogram is to send it back to the manufacture or, you can locate a local repair depot through Onkyo. the Onkyo techs are the only option when re programing is needed.

No home theater sound

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Immediate shut

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck

Receiver shuts down and will not turn back on untill you unplug and plug back in

Nope. sorry to burst your bubble but your problem is pretty common on this unit. Its bad capacitors in the power supply and probably not worth repairing in a repair shop. since this is a solid state reciver, there are no user replaceable parts inside.
