So I am on my second forerunner 265 (the first one got replaced because the altimeter and barometer were no longer working) and the screen suddenly went blank today. I was open-water swimming with the watch for about two hours before I got on my bike and started cycling home. Suddenly about 5 min into the ride the screen went black. It stayed this way the entire ride and when I finished and went to stop the workout the watch ended up shutting off completely and will not turn on. I have tried holding down the power button for a minute and also tried turning it on when it is plugged into the wall. Nothing seems to work and I am a bit frustrated to go and try getting a third watch. Any suggestions on what I can do to make this work? For $450 I would hope the watch could last for more than 2 months as this watch was only delivered to me on May 12.
