I have two tivo's now. My first tivo (B) had a problem after a while and so I put it away in a box and bought a new tivo (A) and now after 6 months that one has a problem too.

(A My tivo series 2 has a problem. My tivo powers on (the green light on the front of the box comes on)....but all I see is a black screen. Does anyone know what this is?

(B My other tivo series 2 has a problem. It would reboot all the time. You could be watching a recorded show and then it turns off and reboots itself. Multiple times. Or it would be recording and then turn itself off and reboot itself. Does anyone know what this is?

Thanks.
