Insignia 55" screen blinking when turned on

I have an NS-55L780A12, 55" Insignia TV, and frequently, when turning it on the first time each day, the screen will come on and about 10 seconds later turn off again. It does this for a couple of minutes and finally stays on. This happens no matter what source I'm using.


Any ideas? It's done this for several years and I never found an answer online, so I'm resigned to posting a question. I'm that lazy.

Re: Insignia 55" screen blinking when turned on

Hello VivBlaze,


Welcome to our community. I never think of myself as lazy for finding a convenient, low-effort way to ask for help. I think of myself as efficient.


As regards your TV, if you haven't already, try power-cycling the TV by turning it off and unplugging it for several minutes. This should serve to reset the TV hardware.


However, if the problem persists, your TV will likely need repairs. Please call Geek Squad at (800) 433-5778 to schedule a technician to visit your home.


I hope this helps. Thank you for writing to us.
