TV:LG 32LN570B-UH
Problem:TV turns on. LG Life's Good logo appears momentarily (approx 1 second) then blank screen. Cannot get audio or video.
Tried all manual buttons with no success. Turned off TV and tried again with no success.
Do I need a new TV or is there a simple fix?
Thanks for any advice.

Clarification Request
Is this only when attempting cable TV?

Do you have a player of some sort that can send a signal to the TV to see if that will display on the screen?

If you go to tvpart.com web sites, one or two boards and you are fast approaching a new 32 inch set. At least in this country.

If you are an electronics tech or engineer then you buy the service manual so you know what to check and see if any https://www.google.com/search?q=32LN570B-UH+won%27t+stay+on&source=lnms&tbm=vid&sa=X&ved=0ahUKEwj8j9qi-8jVAhVKw2MKHTaLAHAQ_AUICygC&biw=1536&bih=732 helps.
