    Hi all,

    I may have given the impression that the RGB output is dead. Nos so, the
opening screen BBC 16k etc., is scarambled and flashes rapidly and scrolls?
from tope left to bottom right of the screen very quickly.
    I'm sorry, I should have mentioned that originally.
Kind Regards, Mark.
