Video issues with Illico 4k terminal

For the longest time now, I have had video image issues with the 4k terminal. It happens more often on recorded programs. when I say issues, I mean these lightning quick flashes. sometimes red, sometimes white lines. both very quick, they don't last but are annoying. I know it's the box because I don't see this with my blu ray when watching a movie or anything else on dvd. At forst I thought it was the HDMI cable so I replaced that but same issue.

I also have occasional issues with recording stuff. I set my programs to record and then when I go to replay them, I see the program was recorded for only 1 minute. that happens on and off. Again, annoying. I never said anything to Videotron because I have a lot of recorded programs I don't want to lose if the solution is to replace the unit.

also, is this thing CEC enabled ? if so where would I find that cause I've been in the settings and I don't remember seeing that feature.
