He has shared everything he has done and made a great deal of it available to us all. He has definitely helped a great deal of us with no personal gains to himself.

Oooh, that black dot wasn't there before. You will be up for a new mosfet then (I'm glad you identified what it was too - I hadn't mentioned it before because it's not a regulator, and it didn't change values for me when the screen was on or off - so whatever it's switching isn't the screen directly).

I'll do some more tracing tomorrow after work, to find where the +20v is generated from. That would seem to be the "thing" for the screen to light up (at least).

I'm not quite sure what you mean by "mv all round"?
