Cable box is constantly loosing connection.

For a while, our cable box, from time to time, would "disconnect" from the TV (the TV says "no signal") and then reconnect a second or two later. Sometimes after this blackout, the sound would completely go out and I would need to turn the TV off and back on again to get the sound to return. I thought that it might be our TV since it is a little bit older. However, our TV went out and I had to purchase a new one. Now the problem is about 50 times worse. I can't even watch TV from the cable box because it goes off and on every few seconds. I have tired all of the recommended fixes that I could find: I have checked all connections (they are all tight), I have replaced the HDMI cord, I have tried different ports on my TV, I have tired to lower the resolution on the cable box (when I did this, it wouldn't connect at all), I have turned off the setting that automatically changes to the best resolution, and I have restarted the box (by signal and by physically unplugging it) several times. There are times that I can watch for a few minutes in-between blackouts, but they are few and far between. We recently reattached the cord (we didn't have any TV provider for several years) and we are close to cutting it again. We can watch the TV directly without any problem, we can stream video from the TV, play Xbox games, etc. The problem only happens when trying to watch TV on the cable box.

Greetings, @dsharkness! Thanks for reaching out to us on the Forums! I hope you are having an amazing day! I apologize to hear that you are running into this issue with trying to enjoy your services through the cable box. You have come to the right place. We appreciate everything you have tried so far to fix the problem! Before we get diving into the account does the coax on the back of the box run to a wall plate or does it go into a splitter before going into the wall plate? Splitters can go out at any time causing issues with the signal going to the box. We look forward to getting this issue resolved for you!

@XfinityMichaelC thank for the reply. The coax cable is connected directly into a wall socket. I also have turned on the low signal indicator and haven't got a low signal indication.

I don't know your connection (audio/video) of course. using your TV's speakers is there sound available (turn up volume to assure the audio should be playing) and working when the video is cut off on the TV?  Is the TV attached to the set top box directly via HDMI cable? if so, when this problem happens, unplug one end of the HDMI then reinsert into the HDMI jack until feeling and hearing a definite 'click'. do same for other end of the HDMI cable. did either reinsertion with a click turn the video back on?
