    Olevia 265T no sound and knocking sound

    Hey All,

    I heard a lot of good things about this forum and I've always been a reader, now I'm hoping someone can help me fix the following issue.

    About a 3 weeks ago, the sound on this TV just went out, I tried everything but NO sound, mute button is not on and I can't choose the speaker icon to ON, but since I have an external sound receiver it was no big deal. But about a week ago, this started happening. Please watch the video. There a knocking sound coming from the TV but goes away when there is no picture. I'm baffled by this very bizarre issue. And just yesterday, the screen now changes color before the knocking sounds start. It becomes either a purple or green haze would flicker on the screen. Any advice will work. Thanks Everybody for reading this post.

          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...
