Green Bar Flashes on screen
About once per hour, I get a small horizontal green bar flash on the screen for less than 1 second. Always different location. It is not the TV or receiver as it does it on two systems in the house. It is lime green in color, horizontal and about 1" wide ans span full screen width on a 55" screen.
So not TV, receiver which leaves Shaw signal or the LNB. Thoughts? If LNB, is the Shaw only or is there a source where I can buy down south? (I have elliptical dish with 4 coax connections with two heads)
