      Any menu functions onscreen?

      Tried any other input sources?

      Any sound?

          LG No Signal cube? Are all inputs dead? What about Freeview/DTV?
          I have a friend with a smashed 32" like this, he might have a main board... I'll ask him if you're interested.

                  OK, hold MENU on TV and MENU on remote. 10 seconds. Does service menu appear? Note: if code prompted try 0000, 3142 or 1234.

                      It sometimes requires a factory remote, depending on the model; someone on a forum said you can use a universal remote but didn't include any code.

                              Really need to get into that menu but can't find anything on it - maybe try googling it a bit more as I only had a brief look, someone mentioned a One 4 All remote working.

                                    If you look on that list, there's many options. One of them involves using an audio output (e.g. laptop, iPod, phone) and an IR LED - if you can get the bits from CPC it could work.

                                        I will give him a call tomorrow and check, he runs a TV/laptop repair shop. He'd probably sell the whole set of boards for cheap, will check with him.

                                          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...

Music starts after like 1 min. After some time logo will Just hang. But i can turn volume up and down on a pilote but its very slow as well.

                                          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.
