I've got a sena prism and the screen doesn't come on most of the time. I have only recorded about 5-6 hrs of riding with it, so I'm surprised it's already faulting. The screen will come on sometimes if I cycle out the battery and charger cable a few times while powering on/off. There doesn't seem to be any info about this issue on the internet. I'm hoping it's just something related to a bad battery. Anyone else have Prism problems? Thanks, Ray
