Anyone know what the power saving mode does? Picked up the 65" last night at Costco after the $100 price drop. Also, the bias light(luminoodle) stays on then goes off, then flashes on and then off. What the hell is up with this? I can't find any info on the bias light. Other than the bias light issue the TV is flawless. It has perfect blacks, don't see any banding or DSE and no blooming.
