Channel 690/190 are tiling and pixating and I don't know why. It seems all the other channels are fine and my cable connections are fine too. Any tips or reasons why?
I was having issues with all three TVs and decided to contact Verizon. A tech came over today (12/18) and replaced the outside box . All my issues with the TV picture have been resolved. I like to add that it was a excellent service and professionally handled.
Do you have more than 1 TV?
If so, does it happen on them all?
I know you said connections are tight, but did you check back to ont and at first splitter.
