I am stuck with a pretty basic issue. Grrrr. I have my trip photos on my iPhone 6. I have the iPhone connected to my TV's Component connection with an Apple Component (5 plugs) AV Cable. The TV Source Input is on Source 3, the Component Connection on the back where the Apple Component Cable is plugged in. Photo slideshow is playing on the iPhone, and the TV screen is black. The audio on videos in the slideshow plays fine, but no photographs Am I missing something?
