Mine is doing the same thing. My last one did it a year ago and had to be replaced after only about 12 to 18 months of wear. Sometimes, it will stay on for a few hours, then shut off. I asked if they would give me a discount instead of another replacement because I no longer trust this model, and they gave me 35% off. I live overseas, so they won't even mail the replacement, but they can only do 35% off when every comparable model is more expensive. Not good enough.
