TV pixelating

TV pixelating on all LIVE channels.

Tech came out in mid July .. tighten up the "outside" cables and the pixelating STOPPED.

TV is now watchable... 

Tech said he will dispatch Field tech to come out to check the cables (outside).

Field tech arrived in the morning today...

Did a bunch test and replace connectors (all outside) and confirmed there are no errors..

However, found the pixelating started again after turning on the TV in the evening...????

Now, I am FORCED working with the BOT (Xfinity Assistant) before I can schedule another Tech to come out.
