I use a device to watch my programs that are streaming. When the freezing starts to happen, it is accompanied by a discoloring of the picture as well. When it freezes every few seconds, the sound still works, and the picture resumes a couple/few seconds later where the sound portion of the show is. When this has happened before,it somehow fixed itself or I unknowingly fixed it. I have tried resetting my tv via 'installation" in the menu, and I have rebooted my device(firestick) as well. When I have everything unplugged, and then I first turn the tv on without anything else connected, the blank screen flickers at the same time/rate that the picture would. It is a relatively new Toshiba flatscreen, so I don't see why something would be wrong with it...especially when it has fixed itself in the past. I would just like to know how to fix it right away, rather than wait however long it takes to resolve itself. It has been going on this time for 2 days now.
