Re: Tech: Centipede image question

Oh, and as for the Self Test, I can't really tell if it's functioning
properly or not... when I flip it, I get a doubled up light orangeish screen
with garbage on it, but since the image is doubled I can't tell if it's
supposed to be like that or what. No beeps or noises when I flip the
switch.
