    You could try toggling between screen mirror and screen extending. Mine was funky like that once and that got it working.

    This has happened to me before. Your MBP screen turns blue when it's trying to detect what's going on on the other screen (the HDTV here). Think of it as refreshing. I'd try changing the resolution if you can, toggle mirroring, or if you can get a display signal on your MBP when you plug into the HDTV, try "Detect Displays".

    It doesnt even let me get to that, before I clicked System Preferences> Display> Gather Windows, and it would show my tv in the window I would click on my tv and mirrow but now I dont have that option

    Try unplugging the HDMI cable from the mDP to HDMI adaptor and replugging it. When that has happened to me this fixed it.
