Doing it enough times corrupts the FAT partition on the sd card. \r\n\r\nThe solution is to plug the micro usb into the pi BEFORE you plug the adapter into the mains.  We tested this in many different combinations and found this to be definitively the problem.  We had seen this problem in the field over the last year but always (erroneously) attributed it to the screen.  The best practice until the problem is formally solved is to always power up the pi in this manner (usb then mains) although it is counter-intutive for most since we plug our mobile phones in the other way (mains then usb).  \r\n\r\nThere are many people experiencing red+green solid leds on boot and the discussion is usually centered on sd card problems or corruption.  This may be the problem.
