TV flashes every 2 seconds for about 2 seconds. Have video to show.
My TV is about 4 years old. RCA brand. Every 2 seconds it flashes a black screen for 2 seconds. At first it would start when the tv is first turned on from being cool. And after 10-20 minutes it used to fix itself. But now it has been about an hour and still doing it. If anyone knows what is wrong then please let me know. Here is a link showing what the tv is doing, sorry for poor quality.
Forgot the link sorry
Is this a good question?
