after i connected the fuse. with the fuse connection removed from the brown wire i tested the resistence between the exposed brown/WH, and it is connecting with no resistance.
If there is no resistance between the brown and white wires with the new thermal fuse removed, the old one is probably OK.
From the power inlet to the transformer, there is:-
1) The fuse in the power inlet
2) the mains switch
3) the voltage selector switch
4) several soldered connections.
As the power thermal fuse is OK, or bypassed by the new one, then one of those 4 things is probably faulty. From this photo it looks as though everything is covered in heat shrink.
I think that you will have to cut some away to work out what has failed. I would start with the back of the on-off switch.
There's no feedback. It's a direct connection. You could cut the transformer wires and poke the ends into a mains outlet and it would work. I'm not suggesting that you do that, as one slip and you could get a shock.
My guess would be that the switch is faulty.
I've just seen your latest picture. I can't see which bit of metal looks discoloured, but I suggest you cut the tie-wrap and insulation from the back of the switch.
I plugged in AC to the wall, i heard a sound like a switch flipping, the light indicating power was not on, I unplugged the wall outlet and the switch sound happened again, rechecked for ohms on the power pins, plugged back in, turned switch on, I heard no switching sound this time and it is not turning on.
Here is what it looks like wiuthout the white wirwe in that hole. is it supposed to be removable? what is that little pin sticking up above the contact?
Success! Turns on and everything works now. All I had to do was clean the connection on the power switrch and re-solder the white wire to it. Therre is a bit of low level noise coming from all of the speakers. Idk where its coming from but im super relieved to have this working finally. Think the noise is the usb interface. i unplugged it and the noise vanished lol
Been mixing with it for hours and haven't had any issue. The people who use this forum are great, thanks for having patience and walking me through all this stuff, I wouldn't have been able to afford a technician and I wouldn't have learned a thing if I could afford one, I feel like I've come back from a weekend workshop. Thanks again.
