In Newport, NC, I saw this thread and checked, my locals are gone too. Haven't had the TV on all day.
Both PBS stations are working.
Does anyone know what happened to GCTI channel 48 ? It's been out for a long time and has the message on the screen like the locals. I thought it might be hurricane related, I think the station is in Greenville, but not the case. My husband has Spectrum at his work and said it is working.
