    Phillips 29PFL4908/F7: Squealing sound and not powering on.

    This happened after the TV took a long ride in my trunk. I figure the vibrations must have shaken something loose or messed up a solder point but I have no clue where. It is making a high pitched squeal when I plug it in and will not turn on. All of the capacitors seem fine.

    Do you have a DMM and know how to check for S/C aka short circuit ?

      I can buy one tomorrow, I have used them before. Could you circle where to test or something like that?

        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...
