Heavy pixelation, but only on 2 channels

[Stafford_AM]

So, for several months now I've been experiencing pixelation when watching either ESPN (1205) or TNT (1404). Every other channel to my knowledge works perfectly fine. It's currently unbearable - sports are back and I need this respite.

Simple, check your cables are tight and in good repair, remove any unnecessary splitters and possibly have a tech out to troubleshoot further. Channels come in different frequencies and whatever is happening is impeding the signal to those channels (maybe others).
