TV pixelation issue

After upgrading to an XB8 modem my TV started pixelating every few seconds. It seems to happen on all channels, but does not occur when I'm streaming through the internet.  If I shut down the modem the TV works fine.  Could it be that the modem drains the signal or creates interference in the line?

Hi @user_pex6lo, 

Thank you for making a new post, so we can provide more help. I see that after you received and activated the XB8, you've had picture issues on your end. I understand; however, it gets better if the XB8 is shut down, which is interesting. Can you confirm if both your cable box and XB8 share the same outlet?  If so, can you check the splitter for any visible issues?

The splitter is a small rectangular box that splits the main outlet into two, enabling devices to share it. Do you see anything like this on your end?

@XfinityVianney​ Two separate lines come into the house, there is a splitter outside. It looks ok the connections are tight.
