Found this LG 42LN5300 in the dumpster, so i thought i would fix it up and share my progress and success in replacing the LED Strips. Tv works great and is super bright.
Be sure to keep the light level at the lowest comfortable level, don't have it on full brightness unless you really need to - this will extend the life of the LEDs.
Same process for most LED TV's as well.
