Our fan in our Tivo was being loud and we tried to replace it. Unfortunately some glue had come loose so when we took off the lid a small black wire towards the front of the box (next to a red, a white, a blue, a yellow, and another black wire) came loose from the circuit board. Any idea what that wire does? So far the Tivo has been functioning well enough without it.
