After calling both WLNE-TV 6 and WJAR-TV 10, I found out that the HDTV signals for both stations was off since Sunday due to the powerful Northeaster storm in New England. The representatives from both stations (which share the same transmitter tower in Rehoboth, MA) said the signals will hopefully be back on by the weekend. Interestingly, WSBE-TV 36 shares the same tower for its digital signal and it's still on the air.
