A first geographical location of a customer premises is retrieved, and a second geographical location of an amplitude modulation broadcasting facility within a threshold distance from the customer premises is retrieved. A first signal transmission power rating for the amplitude modulation broadcasting facility during daytime hours is retrieved, as is second signal transmission power rating for the amplitude modulation broadcasting facility during nighttime hours. A time of day that the IPTV service failure occurs is determined based on the first signal transmission power rating for the daytime hours and the second signal transmission power rating for the nighttime hours.
