YouTube not working on my IPhone?

I have an IPhone 4S, and whenever I try to watch a video on YouTube, it says "This video is playing on the TV", the screen turns black, and a picture of a Tv is above the words. You can still hear the sounds, but there are no images. Does anyone know what this is and how to fix it?

I'm going to the Apple store to fix a button. Will they fix it or replace it?

Also will they fix it there and then? It is the volume down button on my iPhone that is broken. Also if they replace do you think they will let me switch to a white iPhone 5 from a black one?

Thanks in advance.

Added (1). To the first answer. How is getting a replaced iPhone 5 that is a different colour like swapping a broke XBOX 360 for an XBOX ONE. It's completely different. I asked for an iPhone 5s then yes obviously they wouldn't but a replacement of the same phone but in a different colour? I'm sure they would… Why not.
