Here (south jersey) and now (2021) I'm having these exact problems with NBC Sports Philadelphia channel 576 screen freezes and pixilation for 4 consecutive days and counting. Paying over $200 per month including sports fees and severely poor quality. Had to just turn off tv's (2).
Every connection is tight and serivces reset thru Verizon.
C'mon man! Whywhathow is this ever going to be resolved?
