A:Answer It should only be flashing when using your remote. It should not be flashing when watching a show or not using your remote. I would look into if you have a button stuck on your remote, try taking the batteries out and see if the flashing stops, if it does, then it's your remote causing it to flash, if not then it's the tv and I would have it checked out. But it is normal to flash when using your remote to make selections.
