I have cable tv and cable internet with Suddenlink. My cable internet works fine. However, I have a problem with my cable tv. At times the tv picture will hang up and then when I switch channels the tv will have a good picture for about 6 to 10 seconds and then go dark with no sound for 2 or 3 seconds. It will keep doing this until I unplug the cable box and reboot it.
A repairman has been here three times and says there is nothing wrong with my signal strength. The box has been replaced but this did not correct the problem.
Any suggestions since this has been happening intermittently for the past three weeks. Sometimes more than once a day, other times will go two days with no problem.
