Question about Onkyo TX-SR601 Receiver

1 Answer

Onkyo TX -601 Zone two stopped working

Units standby was off and could not power up unit. Unplugged and reset. Power was restored. Since then zone two spkr will not work and subwoofer stopped also. Two pair of spkrs are on zone two terminal through a spkr switch. I connected an old 2 channel to spkr switch and they worked. I then took the unit to auth repair center and they found nothing wrong. Called onkyo support and they asked me to switch some of the spkr wires around and when I did so, the zone two spkrs worked. Yesterday I took the two pair of spkrs from my patio and hooked them directly to the zone two terminals on the back of the unit and they both worked. Today, I took the spkr wire that runs from the zone two termainls disconnected it from the spkr switch, twisted the ends on one of the pair outside and it did not work. It just doesn't make any sense that yesterday hooked directly they work, but if I reinstall back outside, and bypass the spkr switch it does not work

    I have a similar problem. I have three pairs of speakers that I would like to use for zone 2. One pair is in my dining room, another pair in the master bedroom, both are 6" speakers by the way. The third pair are 150 watt rock speakers in my back yard. I have a Parasound amp that is supposed to be set up to power the zone 2 speakers. When it was set up, I was told that it would only be able to power one of each of the three pairs of speakers. Meaning one in the dining room, one in the bedroom, and one out back. Does this make sense to anyone? Is it that I just don't have enough power to run all of the speakers? Or could it be that the system is not set up properly? I don't have the model or power of the Parasound amp with me right now. I suspect that the system is not set up properly because after the installers left, my B&W home theater system sounded terrible. After a few months of messing with the settings, I finally got the hardware configured properly and it sounds awesome!

    Hi Outofit

    With resetting the amp, you may have lost some menu settings that setup zone 2 operation. Go have a look at the setup menu, particularly that for zone 2 activation, pg 55 in the manual. Get back to me here if you cant work em out:)

I have the Onkyo TX-SR605 system. My Zone 2 used to work and now it doesn't. I tried to activate it under the Hardware Setup, but Zone 2 does not show up. Any suggestions where else it can be found

Hello, When you say Zone 2 doesn't show up do you mean that its not there at all, or is it just greyed out? I would suggest a reset of the unit it seems as though either way it could be a glitch. Thanks, FJD

I recently moved and just got my outdoor speakers hooked up. When I turn on Zone 2, I get sound from my Ipod, but when I set Zone 2 to have music play from my satellite box, I get nothing. The music will...

If your satellite box is connected using a digital cable to the 601 receiver you won't get any sound through zone 2.Zone 2 can process only analogue sound ( inputs ).

Onkyo TX-SR605 cannot get Zone 2 to work on any setting other than FM Mode

Have you assigned the zone 2 configuration to the device that you want to play on zone 2?

This is part of zone 2 settings.

Otherwise the problem is with the amplifier circuit and will need replacement.

If the unit is not more than 3-5 years old , then depending on where you are there is a factory warranty.
Check with your Onkyo service centre before touching the unit.

Sound problem, zone 2 speakers work only

A soft reset might help; with the system on, hold down the VCR button and then Standby. The screen will read "Clear" and then turn off. When you turn it back on it is supposed to be just like it came from the factory.

No HDMI Output

My configuration:
ZONE 1 (living room)
DishNetwork Dual Tuner DVR Tuner 1 [S-Video out] -> [S-Video in] ONKYO TX-SR875 [HDMI out] -> [HDMI in] Sony KDS-60A3000 rear projection TV

ZONE 2 (living room)
DishNetwork Dual Tuner DVR Tuner 2 [Composite Video out] -> [Composite Video in] ONKYO TX-SR875 [Composite Video out] -> [Composite Video in] Samsung AQUOS LCD TV

ONKYO receiver stops sending video signal to my ZONE 1 Sony TV through the HDMI connection. ZONE 2 may still receive video. (NOTE: the issue might be related to the upconverter circuitry?)

I couldn't see any video, but I could hear the Tuner 1 audio through my ONKYO. An important clue is that I couldn't see ONKYO's on-screen display menu on my TV when hitting the [Setup] button on my remote. But, I could see my TV's Sony-based menus and display options.

1. Put all ZONES in Standby mode using the remote. Hit these buttons on remote: [Receiver], then [Standby]. [Receiver], [ZONE2], then [Standby], [Receiver], [ZONE3], then [Standby]. You should NOT see any lights on the ONKYO except maybe one red led near the power button.
2. Pull the power plug out of the back of the ONKYO, and leave unplugged for 20-30 seconds. Turning off any power center it is connected to isn't enough. You MUST unplug the power from the back of the ONKYO for 20-30 seconds.
3. Reconnect the power cord to the ONKYO.
4. Using the remote, set ZONE1 to a video source known to be working. If you don't see video, try leaving the power cord off for a longer period.

I know it sounds too simple to work, but that's what brought the video back for me the few times the video stopped displaying. Hope it works for you.

No display on my sr875 the next time i turned it on..i have no clue waht was just working fine yesterday,now, it suddenly shows one issue that needs to be resolve..i did everything i cud do but...

The 10 Ohms resistor R9304 in series with the the 44V display power supply was open.

How to find it:
Remove the to cover.
On the right hand side of the front panel you will see on the side a wide white flat cable going toward the back of the receiver.
Beside it is a 4 black wire band connecting the front panel to a 3x4cm power PCB which is parallel with the front panel inside the receiver (attached to the front frame).
It has visible on the left side a diode bridge and a fuse - above the fuse you can find the R9304, a SFR16 package (1x3.5mm) marked BrownBlackBlack.
Check continuity.Replace if open wit a 1W resistor
Good job ONKYO, save 1/3 of a penny...

For the DIY:
As an added step I replaced the R9304 with a 2W 47R resistor, replaced the series transistor regulator Q9301 (tall TO92) with a bigger package (isolated TO220) and one of the two series 22V zenners from the base - D9310 - with a 10V one.
Output voltage drops from 44V to 34V, display is slightly dimmer but overall stress is down.

Good luck!
