    Most likely it is something else.
    For a start check all power rails going to the hdmi board.
    Do you have video output? Is the OSD working? Is the internet radio ( DLNA? ) working?
    Yes, I have tried connecting to a TV via HDMI output and it shows the menu perfectly. Also Ethernet is working and successfully connecting to home network. Also it's reading an USB, playing tracks but even with Pure Audio enabled there is no sound on this setup (USB Input).
    I think someone tried to repair this board - screws are used.

        In this case you should start with the board connections.
        See the SM for the signal flow paths.
        Once you are sure all boards are connected properly, you can start checking the power supplies on the HDMI board.
        Try tracing the analog audio to the ADC and DAC. If you have troubles doing this, post some HD photos of the boards to pinpoint you the test points.

            Onkyo TX-8050 AV-Receiver no sound
            by ai.need.help
            Hello,

            I have a problem with my Onkyo TX-8050 Receiver. I got it from aftermarket and it was just delivered today.

            It doesn't play music. There is no real output from:
            pre-out
            amp-out A and B
            phones out

            The only real sound I hear is a humming from the speakers when I play a song from usb or select a analog source. And when stopping and starting songs from usb or switching sources, I hear a crack from the speakers.

            I tested with analog-input, usb and radio.

            I know that there is a common problem with...

            what i went through dealing with my mobo with dead onboard sound!
            by ChaosLegionnaire
            so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

            i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

            Onkyo HT-R960 No Sound
            by platinumsteel
            Hi guys hope you all doing fine.I have an Onkyo HT-R960 from my uncle that he says he powered it on one day and no sound at all.I took it to try and repair it.I am also using it as an opportunity to start learning how to repair units like these and also amplifiers. When i first brought it home I also realized it wasn't outputting any video and audio tru the HDMI Ports.So followed a youtube video on how to change 5 caps to get HDMI output back.Did exactly that and now i have Picture tru the HDMI Ports.But still no audio. Checked a lot of voltages according to the schematic and also visually nothing...

            Onkyo TX-NR828 - popping sound every 5 min
            by roman-hartwig
            Object: Onkyo TX-NR828
            Problem: Popping noises in the right surround channel every ~5min
            Service manual: available

            After I was able to bring my beloved Onkyo back to life (total failure of the power amplifiers) and it has now been doing its job for some time without any problems, it is now ailing with a new problem. It still works fully, but after about 5min it "pops" in the right surround speaker for about 0.5 sec very loud (100% volume). I am almost scared to death - sounded like a battery exploding or something. It sounds like something is discharging - a...

            Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
            by LEECH666
            Good day ladies and gentleman!

            I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

            This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

            I think the PSU buzzing comes from one of the coils near the bridge rectifier but...
