For a couple months I've been experiencing pixelating on four New York HD channels, each of which is a duplicate of a Philly channel. It happens on all three set top boxes.
Other channels are fine, including the same Philly ones (NBC, Fox, and so on). So this is not much of a problem (unless one likes New York local news), but it makes me wonder if FIOS is throttling NY channels when Philly ones also are available.
I went through a tedious chat experience with a tech who reset all the boxes and nothing changed.
Verizon doesn’t throttle any channels. If you are experiencing pixelation then you have a bad RF signal. This can be due to a number of reasons from the ONT, cabling, splitters, or the box itself.
Since all three TVs are doing it it most likely is the ONT. You should schedule a tech visit to take a look. Rebooting the boxes and/ONT will not do anything if you have a bad RF signal.
