    LG42LA620V buzzing sound through speakers

    I've got an [B]LG42LA620V[B] that is buzzing from the speakers, the buzz gets louder/quieter when turning volume up & down. I've just repaired the backlights & I'm not sure if the tv buzzed previously or if it's something I've done while replacing 2 of the LEDs from 1 strip ...

    I will update this post later with photos of boards & board model numbers etc...

    Thanks

    A2442 - No sound over internal speakers and no video playback
    by soeren
    I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).

    All happened after the battery ran out of power overall several days when I was on vacation.

    I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery...

    by ChaosLegionnaire

    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...

    Logitech X-140 speakers buzzing is it normal?
    by basskilla
    Hi There!

    I bought secondhand Logitech X-140 speakers,it is old but it think the quality is all right.
    My problem it has background buzzing noise even if nothing is connected to it.
    It is not too loud,but if the room is quiet,it is noticeable.

    if I touch the metal cover,or the tone knob the noise is louder,I have the plastic cover knob,but I don't know is this noise normal or not.Sounds like a grounding issue or something like that.

    I tried to resolder the jack connection but nothing changed.

    Here is a little video about the speakers:...

    Audio Jack on hp-ec1001np detects phones and external speakers but no sound
    by StrongTester
    Hello friends, I am having trouble with a hp-ec1001np that detects the headphones or speakers when connected to the jack, but no sound comes out. The normal laptop speakers work fine. Anyone has an idea what it might be? Did a full reinstall of windows, still nothing.
