I have an LED light bulb: Philips 60W incandescent equivalent

I've owned it for about a year and have been very happy with it. This morning when I turned it on, it started blinking. Not flickering, but a very deliberate one second on, one second off, one second on, one second off. This continued until I fiddled with the bulb at which point it came on and stayed on.

Its never done this before. I unscrewed the bulb and it rattles. Something in it may be broken, but it still seems to work. I couldn't find anything on the Philips website about this type of behavior. Does anybody know what it means?

All I can find is that it's still under warranty. I found a reference to a 3yr and 6yr depending on when exactly you purchased it so it should still be covered either way. –  Jason Mar 20 '13 at 16:49
Does it still happen if you screw it in firmly, or screw it into a different fixture socket? I have had non-LED bulbs slowly unscrew themselves untill they are only just in contact and then, they blink. –  K.A Jan 2 at 4:18

I called Philips about this issue. They said that it indicates that the bulb is broken and needs to be replaced. Some LED bulbs have enough electronics in them that they are able to have diagnostic circuits and to report errors in this manner.
