    HELP!! Marantz SR5006 no sound

    I have a receiver where sound is good on FRONT r/l channel speaker B, but no sound when I switch speakers to A. I can also hear a buzzing noise in the receiver but it is intermittent.

    I am looking into tracing the audio signal on each channel(a/b) as I have a scope. Is it a possible bad output amp or capacitor.

      IIRC they have an issue of blowing the output preamp.
      i work on the 70s and older tube stuff, so i can't really help too much, sorry.
      Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

      You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

      Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

          Audio video receiver KENWood KR-V990D,no sound
          by JRade
          When I select the FM receiver, I find a radio station, the sound is heard on REC OUT(L,R), REC TAPE1(L,R),REC TAPE2(L,R) on high-ohm headphones, the sound regulation does not work.
          The output reacts when I connect the record player to PRE OUT FRONT L, the sound is heard in the speaker but the sound regulation does not work. Then it does not matter what I chose on the front selector.
          I replaced the capacitor C303/0.047F, nothing changes.
          I'm asking for help, what should I do next?
          Thanks in advance!...

          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!

          marantz sr6012 no sound
          by oshimapt
          hello guys,


          first of all i'm not a qualified repair guy, i am a diy guy and as years pass by i have some experience on repairing eletronics, and i'm hoping someone can share their experience.

          i have a marantz sr6012, some times it turns on and works normal, but after a while the sound cuts off or it starts getting distorted and then cuts off.

          when this happens there is no audio no matter the source used, and the OSD shows unknow audio signal from the source.


          i was reading very carefuly the service manual and it is all pointing for...

          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...

          Anthem MRX500 - no sound

          Dear Electronics Experts:

          I have the following problem I am trying to troubleshoot. Unfortunately, I have contacted Anthem themselves and even a local distributer but I am not having much luck. Also, I have scoured the internet and unable to obtain a service manual. The Anthem service rep has also replied that he is unable to provide me with any service documentation. I have performed numerous searches on the internet and cross-referenced a few other AV receiver makers (Denon, Marantz, Onkyo) and found certain similarities to block diagram...
