This is a 50 inch samsung tv no p550c450b
No .....I want to show photos from my camera but the AV does not light up on the menu
No pop up window appears
All checked....pressed media p button and pop up says no external storage device found.
How do I return to factory setting's as this AV setting used to work last month
Cannot get initial set up menu to show on screen
Nothing ......forget it and refund my £20
