LG TV - powers on, but black screen after LG logo, backlight is on
ANSWERS:
It’s a problem with the motherboard.
Hold down power button on bottom of tv for 10 seconds when it’s on.
the Led back light is bad, leds connected by series, one dead all will not work, check this video: https://youtu.be/LaV6aQ8LIpw
I've been stressing about this. My tv would go dark only if the picture was dark or tv seen was at night so I would crop the picture and have a steady on background on the section that would go dark.
