    I had my TV set at 100% before I took it apart.

    So, any current below 350 will still power the LED, right?

    I used a 6V power brick, and was able to find the one bad LED which caused the whole side to go dark.

    Each strip has a 4 wire connector daisy chained.

      The LED can be driven up to 350 mA @25c so less current will be less brightness, you always want to drive the LED at 25% less than the max spec. If you look at the LG spec I provide, it does say not to drive at max spec.: "The exposure to the absolute maximum rated conditions may affect device reliability."
