              Can you post some pictures of inside of the unit?
              Slow menus could indicate a processor that is busy doing something else -- perhaps trying to initialise the sound but cannot do so.

                  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...

                  Visio V755-G4 LED TV: No backlight, have sound, see menu with light.
                  by Grasshopper2Ant
                  No backlight issue. Have sound and can see menu with flashlight.

                  Suspect LED driver, voltages are 100V each side. What should the voltages be for 75 inch TV on the Power Supply Board? I have 96 leds x3 volts per=288/2=144 volt per side?
                  Am I low on my volts causing the leds not to light up?

                  Before I got all backlights out, the right side was a bit darker than left side. How many leds
                  need to be out for all to not work?

                  Thinking of getting a led tester. If leds light up, would that confirm it is the Power Supply Board?

                  I do not want...

                  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...
