I have a Motorola 6200/1000 cable box. The unit powers on, but a "0" appears in the left most LCD position of the display. I looked on line, and found that an error boot code of EP00 in the D01 position (which is exactly what I have) indicates a fan failure. The suggested fix is: replace the fan or box. My questions is: I was under the impression this model cable box does not have a fan, so how can I be getting a "fan failed" error message? Anything I can do to reset this unit and remove the error message?
