Panasonic TV Blinking Red Light 3 Times [7 Easy Solutions] 

As the Panasonic TVs have built-in circuits for fault diagnostics, whenever an abnormality occurs on the TV, the protection circuit operates and resets to standby mode. The number of blinks represents the exact error on the TV.

Panasonic TV blinking red light 3 times occurs for over-current or over-voltage protection. When there is an interrupted boot program caused by the A board, the TV starts blinking 3 times.
