Since I've upgraded from Retina iPad 2 to ios 7 whenever I try to connect it to my Sony Bravia TV the output colours have a horrible pink cast over them. The picture and sound are both fine but the pink cast remains on whatever App I try to use. Before this I used the same cable, HDMI adaptor from the iPad and the same TV. There must be something within the new ios that is making this happen. <br><br>I'd love to go back to ios 6 but it seems like a complex process. Has anyone else had the same problem? Thanks for any advice.
