    Marantz NR1501 no sound at all.

    Hi.
    This receiver has no sound at all, also not on the headphones. In the service mode is said: check DSP. I have added 2 1000uf 16 volt caps one at ic 1006 and a other one parralel to C1204 on the DSP. I also found out the 5 volt was only 2,1. So I swapped the IC201 5 volt regulator. 5 volt is now ok.
    I am looking for the update software cable and software itself. There is no DSP ROM value seen in the service mode. The field is empty. For those with an eye for detail: service mode values I found:

    Firmware: 090921-1
    DA: 9-2
    DSP: (empty)
    HDMI: 10042011

    So there might be a update necessary. Can anyone help me?
    Merry christmas!

              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...

              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...

              Marantz SR5012 popping and other sound issues
              by acedogblast
              Hello I have a Marantz SR5012 7.1 AV receiver that is producing speaker pop and other sound issues. These sounds are coming out of all connected speakers regardless if they are configured to be used. The rca preouts are clean from these defects so I am assuming the problem has to be with the amplifier.
              These sound issues are random and unpredictable. There are times where the unit can go 10 minutes without any problems then suddenly the problems come back. It doesn't seem to matter if there is sound being played or not.

              I have disassembled the unit and was able to take out the...

              Marantz NR1601 No Sound, Schematics attached.
              by Benass
              Certainly! Here's a revised version of your text:

              ---

              I own a Marantz NR1601 receiver, but unfortunately, I'm experiencing an issue with no sound coming from any of the outputs. I'm seeking assistance to identify the most likely cause of the problem.

              The unit powers on without any issues and seems to be functioning properly. I've noticed that the relay clicks after about 10 seconds, indicating that it's going through its startup sequence. There are no visible signs of damage, and I don't detect any burnt smells.

              While the schematics provided...

              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...
