(PG) Boy oh boy – I don’t know who would have paid heck if this had happened during tonight’s Steeler game! Those watching WPGH-TV (53) over the Comcast Cable feed were watching the Carolina Panthers and Green Bay Packers without sound. Around 1:00 PM an audio switch on the transmitter quit feeding the sound to Comcast which wasn’t restored until around 2:20 PM. The over-the-air signal still carried the audio.
