    No sound on one channel using RCA input

    Hi I'm trying to figure out what's the issue with this amplifier, Its a 2.1 channel system Dixon system (not a fan of this brand).

    Issue:
    -While using RCA or line in inputs the subwoofer plays and one of the speakers.

    But if I connect via Bluetooth all speakers play fine.

    I replaced the TDA7379 IC because it was previously blown with no sound at all.

    Please if anyone can give some advice? and if you need more photos let me know?


    Thanks

      if tones and vol work on bluetooth look at the switching ic.s for mode switching if it has them

              Onkyo TX-NR609 Sound only on USB/Internet Radio/DLNA Input
              by Sushi1808
              Hi everyone!

              I turn to you in hope someone could point me in the right direction since I lack knowledge and experience in diagnosis of audio equipment. (My experience is in computer chip level repairs.)

              I bought an Onkyo TX-NR609 receiver which initially produced no sound on speakers/headphones, there was no delayed relay click, speaker matrix icon didn't show up, USB/NET stuck in "Now initializing", instead of DSP/1st NET firmware version there were ?????????...

              There was flux residue around the D830K013BZKB4 DSP chip (Q3001) on the HDMI...

              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...

              old X58 triple channel board... memtest86 memory speed?
              by eccerr0r
              Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.

              Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...

              Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any...

              820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?
              by ugamazing
              So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

              1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

              2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

              Onkyo TX-SR805 noise in one channel
              by MegaZAC
              Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

              Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

              There's some logic behind it. As soon as I select an input I get only left...
