Problem with lightning hdmi adapter
I Just got a new lightning digital av adapter To connect my iphone 6 plus to my tv. Initially it was working great, then I received a phone call.. Since then nothing. The little blue bar comes up on the top of my iphone screen for a few seconds, then it goes away. If I try watching any video, it displays only on my phone screen. Tried connecting to my ipad mini, and it worked just fine. I'm sure there's a simple solution but I'm stumped. Help would be much appreciated.
iPhone 4, iOS 6
