If there was a problem with gnd, I guess I wouldnt be able to measure voltages using the gnd point on the ISCP socketSnoozr wrote:Maybe check Gnd continuity all the way through to just before the power socket? I think I saw in another thread that Vincent said grounding was an explanation for no sound throughout. It's funny that your multimeter probe makes things work.
The probe is actually just an audio cable inserted into a cheap usb soundcard. I don't even have the ground connected to that cable (but it's grounded from the main out to my firewire interface)
I just replaced Q27, nothing changed. Giving up for today.
