Samsung NU Series Backlight Failures

There are lots of reports on the reddit tvrepair subreddit of NU series TVs with failed backlights. NU is a 2018 model year and backlights are failing after 2 years. These models are edge lit from the bottom so LEDs that have burnt out will cause dark vertical bands or sections.

Some model numbers include

UN50NU6900F UN55NU6900F UN55NU6950F

With the screwless back cover and edge lit design, replacement can be pretty difficult especially on a large screen.

It is always recommended to never run your backlights at maximum which shortens their life.
