We have a 55" Insignia LED television model ns-55d420na16 in which the red standby light at the bottom flashes as though its coming on but the screen is totally black.
In some cases you may have sound coming through the TV but still a black screen with no picture.
We are going to totally tear down the TV and replace the bad backlight led strips to get our picture back.
