    Medion LCD - no sound - Bad cap?

    Hi there,

    A friend of mine got a problem with a medion lcd (type md 30178).

    There is no sound. Sometimes, if the tv runs a few hours, the sound appears.
    If i connect headfones to the tv, the sound works everytime.

    I looked inside and found this cap (1500uF /25 V). It is located next to a TDA8933t (Class-D audio amplifier).
    https://www.dropbox.com/s/1x938xn7v5...%2032%2007.jpg

    What do you mean, will the sound come back after the change of that cap?

    Greetings

      datasheet here

      prone to failiure

      check vcc to ground for short

      check voltage to vcc

      could be cap issue,does volume sound low?replace those bulged caps,look like teapo to me

      replace with panasonic fm series ,taking note of can size for fitting

          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!

          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...

          Marian Trace Alpha sound card repair help
          by Christos Tsiligiannis
          Hello to the forum.

          My name is Christos, I am new to the forum here and i am posting from Greece.

          So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.

          To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.

          So i tried asking for a schematic from the company and they would not give me one. Instead they...
