    Re: Lg32ld490

    Hi There,

    I also have an 32LD490 which has recently failed, but in a different manner.
    I get no response from it at all; the red light just flashes really slowly. Freaky thing is this continues for a good few minutes after disconnecting the power cable! Very Maximum Overdrive.

    Had the back off and checked the PSU board. All the converter outputs (24V, 12V & 3.5V) are present. The 3.5V line is maintaining its voltage for a long time after power off so I'm guessing the fault lies somewhere down stream of that; possibly with the switching regulators on the main board?

    I don't suppose you might know where I might be able to get a replacement main board from? I tried Googling EAX61531909(2) but all the links I followed showed "no-stock".

    Failing that, I don't suppose anyone has a copy of the schematics for this board so I can really get stuck in? Again I tried Googling, but mostly came across sites with .tk domains requesting credit card details!

    Thanks for reading this far; any help would be appreciated.

        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...

        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...
