Problems in Deer Park, il

Noticing pixelation in channels 571 and 592 over last few days. These channels share 123mhz which happens to be main o'hare aircraft frequency. With construction in neighborhood, some cables were recently repaired, but this would indicate a possible main cable compromise. The Xfinity assistant is useless for reporting these kind of problems, just wants to reset my cable box when in fact it's happening on all of the cable boxes and they recently rebooted. Who else in this area has the same problem?
