Well, thanks to everyone for their help on my A2000. Now that I've cleaned it out (you wouldn't believe how much dust there was inside!). It seems as though this machine is having some more problems. It now shows the self test screen colors in the following sequence: dark grey-light grey-yellow. Can somebody *please* help me out! I don't want to have to confine this machine to the trashpile! Also, if someone can direct me to a PDF version of the manual, I'd be very appreciative!
