I have an Onkyo...

I have an Onkyo receiver/amp model no. Tx-nr509. The sound seems to have died about 4 months ago. Wondering if it's worth fixing? Searching it seems you have to live in Canada, USU or Europe to get any joy. I live in Sydney, Australia. Regards. Peter

Technician's Assistant: What's the make/model number of your stereo? How old is it?

TX-NR509. Maybe 4 years old

Technician's Assistant: What happened right before this popped up? What troubleshooting have you tried?

It appears all functions are working through BVD player, TV & cable TV box, radio but no sound even though controls show sound control

Technician's Assistant: Anything else you want the theater expert to know before I connect you?

If it's worth having fixed?

Since all 5 speakers stopped sound, I unplugged all devices which from remote and manual control appear to be working apart from no sound. I just tried the receiver FM & AM, still no sound. I tried re configuring the sound set up. Still no joy.
Phone call session started

Unfortunately, Premium Service / Phone Calls only work with US numbers. Apologies for any inconvenience.

Still, have you considered / tried a RESET ?

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
Sorry was just re connecting all the speakers again. Ok I can try again, but not too confident

Consider a RESET. A reset is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed. If have not been done and should you venture to try: Please click / tap HERE.

May have to be done a number of times.

This is very critical - a reset however would not be corrective of an internal hardware concern; but it would be confirmed. In some instances, it may even expose/cause other issues.

Tried it a couple of times still no sound on radio stations

And can you please try plugging in a pair of headphones? ...a couple of times; i.e. plug-in / unplug...plug-in / unplug

It requires a large jack. Have quick look

Yes as this would be the standard 6.3mm (US ¼ TRS) plug.

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
Sorry I can't find one. Trying to find a stereo plug but no luck

The headphone jack has a hidden speaker cut-off switch hence the headphones would serve for test purposes.

Still and to my understanding, the Australian version has a Direct and/or Pure Audio mode. Can this be tried please?

How does that go? It currently is recognising a local station

In some versions, there would be a PURE AUDIO button above the headphone jack.

Sorry, don't understand; "...How does that go? It currently is recognising a local station..."

Sorry have pressed pure audio button. I have male eyes.
Customer reply replied 6 months ago
Button on. Display has turned off

Display OFF is to be expected.

PURE AUDIO off, can you try Listening Mode / Direct?

Customer reply replied 6 months ago
That's on
Customer reply replied 6 months ago
No sound

As it would be be an internal hardware issue, are you then considering/attempting a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even perhaps a soldering iron?

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
Multimeter is working and have solder & iron

Great on the DIY!

Onkyo issues, circuit board

Appreciate the picture.

Still, let's try check and review the basics. Proposed preliminary tries (if have not been done):

  • • check fuses F6901A and F6902A;
  • • verify that power relays RL 691, 692, 693 & 694 are engaging;
  • • detemine if the speaker relays are clicking on RL662, 660, 663, 665 and 669;
  • • test for +/-56.2V @ P6901B & P6902B respectively.

A friendly reminder: voltage measurements by its very nature requires that the unit be plugged in and turned on. It is therefore LIVE! Please exercise due care and caution.

Incidentally, was this TX-NR509 working before?

...or was it tried to be repaired / modified in some way?

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
I bought it new. Everything appears to click on. The speakers were originally working on all 5, then towards the end only on the central which is on a separate board. I'm just double-checking the fuses
Customer reply replied 6 months ago
I'm not really qualified to pull circuit board s apart

Have you at least checked the 2 fuses ?

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
both fuses fine 0 ohms

The primary suspect would be the two (2) STKs power pack IC modules attached to the aluminum heatsink.

Only if comfortable with, check for the presence of +/-56.2V @ pins 1 & 2 of each IC pack using the chassis as common ground.

A word of caution; it would be very easy to accidentally / inadvertently short the pins with the metal portion of the multi-meter's test prod.

Ask Your Own Home Theater-Stereo Question
Customer reply replied 6 months ago
56.5V registered on both
Customer reply replied 6 months ago
Don't suppose it's the sound cards?

"sound cards"???, the 2 black IC modules? ...possibly.

Again only if comfortable with:

  • connect speakers to the FRONT L & R and the CENTER;
  • turn on the Onkyo;
  • hold the black probe of multi-meter;
  • touch the red probe to pins 10, 14 and 15 if STK 443-530 / Q6001.

Customer reply replied 6 months ago
No voltage on 10,14 & 15 on STK 442-730 and stk 443-530 pin 10 55 V, nothing on 14 & 15
