strange philips 37pf3720A/37B LCD power problem

[pvkq]

I have a strange power issue with my 37PF7320A/37B LCD tv. After plug in the tv, I can hear one click, the red led flashes once, the green led lights up for a couple of seconds, then another click and every thing goes dead. Press power button, nothing. A funny thing is if I turn off power (unplug) to the tv a second or two after the first click, the back light comes on for an instant. But if I turn off power to the tv a few second after the second click, no flash of back light. I already checked resister 3318 and it is fine. All caps on power board and AUX power/audio board look fine. I also measure AC at the main rectifier and it is 0V after the second click. Please help, thanks.

Do you know the chassis numbers as printed on the model sticker?
