TCL Roku TV flashing like camera

Every night about 30 minutes after my TV has been turned off I hear a quiet but high pitched squeal followed by two very bright flashes. It will light up my entire room like a camera flash would. I have had the TV for nearly 3 years and it just recently started. I'm clueless as to what's going on.
