I think it might have something to do with power consumption. I noticed a high-pitched sound when I plugged the PBP into an alternative power source (5.2V if I remember correctly). This would explain why in your case it starts if the brightness of the screen is higher: the brighter the screen, the more power the PBP needs to consume.
If I were you I would try different other power sources of different amperage to see if this happens again.
