Hello, i opened a new tread to receive help to consolize my first mvs, But before starting to consolize it i must fix mainbord no sound iusse. This motherboard was sold me for really cheap money with no sound, i opened it and i found that on motherboard slot1b ym2610 pin 14 was soldered with a wire to cartridge b50 pin because the trace was cutted, i removed the wire and rebuild the trace with a little piece of wire. After that i checked that the game was running well without sound and i entered into service mode to test the audio but there are no sound test menu. I checked caps for someone blown but they are all ok, i would like to check the ym3016 but i cannot check it because i cannot test sound into the test menu.
