The WSoD has to do with an power problem on the LCD chip, although I'm not sure what exactly causes this failure. Some people have got it by plugging in the AC adapter, then immediately trying to power up the unit...that's exactly what happen to me on a prior unit. I do know that in most cases if your going to get the WSoD then it tends to appear within 10-20 reboots of the device, although I've seen some people get the WSoD over a year later. I've never heard of someone getting it just from reflashing the unit.
