Just went to start my box and make some more measurements and it would not boot. All I had was the initial Dream logo just before it shows the SSL version. Whilst in that state, I measured the main power connector and most things were ok, but that pin 10 you mentioned was jumping all over the place. I could not get a steady V reading on it.

Switched the box off, then back on and it began to boot. Once it was booting, pin 10 had a steady 3.35V.

Any clues as to what would cause pin 10 to jump around like that? Seemed to be something switching on/off rapidly..

Regards,
Hoffy.
