Re: Picture on TV blinks on and off every few seconds when source is the cable box

I have had the same issue for many years now. Comcast techs come out to the house replace the cable under the house and the issue continues where the TV signal blinks on and off, sometimes staying off for periods as long as 30 secs. The only thing that helps is resetting the box, plugging and replugging AC to box. However there are times when the issue will return only a few moments later after resetting the box. It doesn’t matter which port the box is connected to and I remember a thread mentioning weather changes can cause this, something about frequency. Not really sure what I can do about the weather.

It’s so annoying to pay so much for service and never have this issue fixed. This issue is not isolated to the living room cable box, we also have one in the bedroom and that one seems to flicker more often. Sigh.

Every morning we have to reset our cable box. Because, the picture is flickering in and out. The issue is only present when watching from cable box. So we know it’s not a tv problem. Has anyone found a solution?

Hi, @user_3de17f

I understand how frustrating it must be to have to reset your cable box daily. That would drive me crazy. We do want to help with getting this resolved for you, ASAP. Since this is an older thread, it will be closed and inactive moving forward. Please create your own public post so that the community along with us employees can help from there! 

I no longer work for Comcast.
