Yamaha RX-A3010 working, no sound output

Re: Yamaha RX-A3010 working, no sound output

Also S4-1 SYSTEM VERSION is having the same problem, displaying "----" as well as S4-10 DSP2 VERSION displaying "-------" S4-11 DSP2 CHECKSUM showed a value of "8A7BC1FA" after several minutes.

I'm swaying towards IC521 being at fault here. But then could this be a general firmware issue? Kinda sketchy running an update on faulty hardware, could brick the remaining good chips if that DSP2 is messed up.


I've pulled the board with DSP2 chip on it. Maked D81YK113BZKB400. I've had a very very similar if not the same chip fail on a Denon or Onkyo unit where a test was to heat it up and sound was coming back, while reflow would bring it back for slightly more time. Replacement was needed regardless.

I have performed a reflow of that BGA IC. No change in behavior tho. Hmmm....

Re: Yamaha RX-A3010 working, no sound output

Getting somewhere, completed some of the tests from service menu. Unit failed to output any sound using the internal noise generator through the DSP. Then I went to do the test of DSP from page 54. Test section C2-1 BUS DSP2, the result is that it is stuck on the "Checking" indicating "--" while other tests take max few seconds for the result. Looks like this is the issue. All the tests from section C1 completed successfully with no errors.

Will do tomorrow.

Re: Yamaha RX-A3010 working, no sound output

I've never said that I don't want to fix it, I just wanted to get through the easier and possibly obvious stuff first since this AVR is very complex, I wanted to save the digging through schematics for last. Looks like it's the inevitable.

The easiest thing to do is to go through the service menu tests. That will narrow the possible causes..
pg26 form the SM shows the service menu structure
pg36 explains each option and what results should be expected.

I'm starting to think the op doesn't really want to fix the unit

Re: Yamaha RX-A3010 working, no sound output

eventually, the link does down load a service manual but it certainly is disturbing to have to jump past so much "garbage".

Sorry guys, I'm using strict adblock and do not see any internet shit.
I tried uploading the manual on the forum, but no luck with the file size limit and thought this free file upload service was fine.
I do not know if I'll be able to remove the link now, and just to stay safe - download the manual from here https://www.hifiengine.com/manual_li...rx-a3010.shtml ( requires free registration ).


p.s. the edit option for the previous post has expired
Here is what I got on the anonfile link when I click on the "download"... I was not aware there was spam, malware or garbage. Again, I'm sorry about that.
And I highly suggest that everyone should have an adblock installed on all devices!

anonafile wants to install virus's before you download anything.

Re: Yamaha RX-A3010 working, no sound output

I'm starting to think the op doesn't really want to fix the unit or lacks the necessary knowledge and skills to do so.
Also I suspect he does not have the service manual, so I'm uploading it for him ( credits go to hifiengine ).

I'm gonna write this one last time - check the voltage rails on the main PCB!
Before that, go to the service menu and do the tests!
This will show you at least which components are experiencing issues.
Download the service manual, read it carefully, and do the tests. As I said before - there are even test signals which are put through all or individual channels.

Page 97 from the manual - here is the power supply schematic. I counted 20+ ICs on the digital(main) board which you should check if they generate the correct voltages.

Re: Yamaha RX-A3010 working, no sound output

Reset procedure was completed successfully but the unit behaves the same, still no audio output. Currently I don't have a HDMI source to test those inputs that way, will look for some.

As for the headphone test, just tried it with stereo analog input and the result is the same - no audio on headphones.

Re: Yamaha RX-A3010 working, no sound output

one other thing about the "headphone test"... you indicated no sound from the headphones.... BUT you need to try an iinput of analog (and see an input signal identified on the status screen). This may help narrow down where the issue lies depending on the outcome.

Re: Yamaha RX-A3010 working, no sound output

hopefully a full reset will help. there isn't much to go on for the err10 other than an internal error but doesn't point to any specific area which would have been nice. Guess yamaha wants the service work.... :-) Your "coax" test is somewhat telling that the front end has issues (ie. pre processor)... again an hdmi input might be better as then your are dealing with a specific "standard" and you may be able to narrow down where that is on one of the boards. Further, the hdmi standard has things like "5v" associated with it that might point you closer depending on what the result is.

Re: Yamaha RX-A3010 working, no sound output

Try this reset: this is for the RX-A1010 https://usa.yamaha.com/support/faq/a...sual/9441.html

Alright I will try that shortly

Re: Yamaha RX-A3010 working, no sound output

somewhat yes..... although the analog input doesn't provide much detail. If you can, please try inputting a digital input (ie. dvd or bluray). This may check the front end decoding / signal detection / conversion. I haven't looked at the signal flows (especially associated with my a1010) as to whether all signals are digitized and then handled in the digital domain then finally output / converted to analog at the output stage.

Also, as suggested by the previous poster, does the speaker check / setup / test signal work?

Further, what comes out of the headphone jack? Does the unit indicate a change in terms plugging in or out of the headphone jack?

I've used coax input this time to test (known good source that actually works on my onkyo right now) and this was the result, to me it did not recognize it at all. I correctly switched it from analog to coax in setup of AV1 input.





Plugging in headphones results in relays switching, I assume speaker cutout. So it does recognize them, yet no sound from headphones.

More.... have you tried a factory reset? Have you looked into the "silent cinema" feature?

I did look into that feature, looks like a gimmick name for headphones output to me.

I also somewhat tried to find a complete reset option, but I just cannot find it, manual does not really help in this case either, or I'm just blind.

another idea... get a microphone (any microphone) and plug it into the calibration input and see what the system detects and does.

I have an original IPAO Yamaha mic from another set that I had since new, upon plugging in it immediately asked me if I wanted to perform the automatic process of speaker calibration, I confirmed. Maybe a minute passed and this popped up:

Is this what you're looking for? Images made while connected with analog stereo input via front RCA, playing stereo music into it.

Re: Yamaha RX-A3010 working, no sound output

You should be able to generate test signal to each speaker output from the service menu.
Did you check the voltage rails on the main board? There should be 5 or 12V ( not sure about the value, check the SM for the exact number ) coming from the standby power supply and probably the main transformer which are then converted to 1.8v, 3.3v, 5v, 7v etc. You should check all of that rails and for ripples.

Re: Yamaha RX-A3010 working, no sound output

so what does the "status screen" display on the tv when you have a signal input. There is data about the type of input, bit rate, etc...
