Yes Tony, the fuse is open and H.O.T blown ,could still be bad flyback even
though it checks good. In case it is , what are you paying for them out your
way? Do you have a part number for this piece. The power supply is running
as far as I can tell. Can you pass on the information to confirm the horiz
drive location unless it is scan derived. If it is there will probably not
need a print.
thanks
Bruce.
