For experts to discuss very technical stuff and newbies to ask why the Spectrum they bought off ebay doesn't work.

I bought the +2/+3 cable for this machine. Managed to get the cable working last night by moving the 12v wire to pin 1 ( it was on pin 3 )
Excellent!

Do you have audio via RF? If you do, then you’ll probably want to make sure pin 3 of the DIN connector is connected to both pin 2 and 6 of the SCART. If not, then it’ll make sense to see whether you’re missing both the sound from the gate array and the AY chip or just the AY.

I bought the +2/+3 cable for this machine. Managed to get the cable working last night by moving the 12v wire to pin 1 ( it was on pin 3 ) there is no sound yet but the audio wire is connected to pin 5 and not 3. I bought this cable from Cool Novelties and it's the first time I have used them. :evil:
I’ve used Cool Novelties for RGB - SCART cables before (can’t remember if I have ever got one for a +2A/+2B/+3 from them though). My most recent cable for them was for a Acorn BBC/Master/Electron.

When you say you moved the 12V wire to pin 1, I presume you mean in the DIN plug.

Yeah all the pin moves I have talked about are all at the DIN pin. I got the sound working this morning by doing the wire move so the cable works now. My new cable from Retrocomputershack arrived this morning and worked from the get-go. I’m not sure what happened with the other cable maybe someone had a black-out but It’ll do as a spare or if I need to kit bash a cable.

Glad you got the entire thing sorted out!

Well, 8-pin male connectors are a little more tedious to solder than your common 5-pin jobbies. Then again, nothing beats the 13-pin DINs for my Roland GR-55 system. Boy, was that a fun time. :D

Atari ST’s use a 13 pin DIN for the video output connector, and a larger 14 pin DIN for the external floppy drive port...
But mini DIN are the worst...
