Hope you didn't kill your TV, dang that is bad luck. You mentioned a silver box out by the dish that has wires from the feedhorn going into it, that may be a 'downconverter', if your wires coming out of it go to the receiver. The earlier cband electronics were an lna on the dish, wired to a seperate small box called a downconverter, later models the lna/dc were combined to make one unit called an lnb (low noise-block downconverter). If you knew all that was good, you could make it work on your Coolsat, but you'd still need a way to change polarity of the signals.
The feedhorn usually has a small blue box on it that worked off dc current from the older analog satellite receivers-they sent the voltage to change polarity when you change from vertical to horizontal channels. That's why you could really use the newer thing on the dish-the c-band lnbf, which changes polarity using voltage sent to it from the coolsat. No tiny motor, the blue box that is, to worry about. Post some pictures of your lna and stuff if you can.
