Yes, is the footage moving or not? But I'll gove you two different scenarios for it. If the footage is moving, your best bet is probably the corner pin tool and track the footage, especially if the tv appears to be curved or fish-eyed in the footage. Basically, just the track the footage onto the tv. If the footage is static, then it should be easy. Just place the footage onto your tv and scale it however need be to match the tv, and that really should be it. Also, this might be useful to you:
