I have just spent over an hour on this machine and still same thing. The answer your question Mitch, the logo does not appear when i turn the power on. When i hit the power button its just a scrambled mess, colored lines, blank screen, and noise. i have three 2600 systems and never had a major problem with them. Of course something like this would happen, I finally got a 7800 and I cant get the damn thing to work.
