I just bought a brand new Toshiba 52" LCD TV yesterday at Costco. The model number is 52HL167. We brought it home, set it up, plugged it in, and it won't turn on. There is a yellow LED light on the front of it that keeps blinking three times over and over again. According to the manual, that's normal when the TV's powering up, and you can turn on the TV when the blinking stops and it's in standby mode. The problem is, the blinking doesn't stop. It's been blinking for 24 hours now, and we still can't turn on the TV. We called Costco support, and the lady said she's never heard of that. She's supposed to call us back tomorrow after she gets in touch with Toshiba. In the meantime, I am REALLY frustrated at having spent $2000 on an item that won't turn on. Has anyone else heard of this, or have any suggestions? The TV is plugged into a surge protector, I have tried powering it on by pressing the actual power button on the TV, I held the power button to reset it, I unplugged the cord and held the power button to help disperse any electrical problems, and nothing has helped. Any help would be greatly appreciated. Thanks!
