Yeah that was the idea... using a resistor so that even when the backlight setting on the TV is set at 100, the actual power to the backlight would be like 70% of that, thus improving the life of the LEDs. This is necessary because the backlight setting will revert to 100 every time the TV...

Someone in another forum suggested that it's the current spikes when you start the TV that are the problem, so a couple of reversed biased zener diodes across the power rails for the LEDs would probably solve the problem.

I bought a 65" LG UH5500 for $20 at a yard sale because two of the backlight strips were burnt out on the bottom right corner. Opened it up, replaced the strips, TV worked fine for a while... then a strip on the lower left corner burnt out. Opened it up again, replaced the strip in the lower...
