a pic of the projector and top control panel

and
"Each projector has a unique serial coded panel and it recognises only that
one; replace it with an unauthorised panel and the projector will not work.
Therefore, should a thief obtain even one panel, they will not be able to
re-boot any machine but its manufactured partner."
so presumably the only chance is to find some powerFET control switch or
something simple like that
