    Digimate DGL3201 no sound

    32 inch lcd model. powers on good. picture is ok. sound is no more. when i first got this item the sound was haywire. it would work for a bit then i would get a hi pitch squeal. i would have to shut it off then turn back on then the cycle would repeat itself. now there is no more sound. tried external speakers thru the audio out port and nothing there either. any suggestions. pics attached please advise if any further info is required. thanks.

      A picture showing the interconnections would be useful. As it is, I can only guess which of two sections are for audio.

              That looks like the audio amp is in the upper right corner of the signal board. Is there a part number on that IC?

                      That's it. Here's the datasheet.

                      I'd check the power supply voltages, then replace all caps in the neighborhood.

                              From your explanation, you indicated that your also try using the AUDIO line out (RED/WHITE RCA jacks) and you still do not get the sound. The Audio line out signals ARE not generating from that APOGEE DIGITAL AUDIO PROCESSOR/POWER AMP IC by looking at the DATASHEET hook up diagram, may be I am wrong.
                              Please clarify, since I do not see any AUDIO LINE OUT RCA jacks in your pcitures.

                                  Sorry no i only tried the audio out port, i think it was the headphone jack, i'll have to try the rca outs and get back. thanks.

                                      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...

                                      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...

                                      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...
