      Update.
      new cable arrived. Fits much better than the generic cheap one.
      Problem with the OSSC persists as before. Connecting to my 10” crt yeilds unsatisfactory results also. It will give sound but no picture in both 50/60hz modes with the new lead. The old lead will supply picture and sound at 50 and rolling picture and sound at 60. I believe the problem may lie in the Megadrive DIN socket, which may have been put out of shape by the bad fit of the cheap cable, or the clock crystal needs replacing. Interested to hear thoughts!

        Hmm. That sounds like a console issue to me.

          Thanks for your reply. It’s a basic cheap Scart lead so I don’t know the specs. It was bought on eBay from Hellfire Trading. I have a decent cable on the way and will be able to test with a crt soon. I did notice when I took the console apart that part of the mod switch was touching the ground plane so I may investigate that further.

          The cable plug doesn’t fit particularly well in the console. Moving it around produces a reaction on the screen but only in 60hz mode. Cable/socket/capacitors are my biggest suspects at the moment.
