    I have the HDMI cord, the mini display port, the macbook and the tv. I plug them in, the screen on my macbook goes blue for a while, but then on my HDTV it just says no signal. When I unplug it though it says no connection so I can see everything is plugged in. Just doesn't seem to be working. Suggestions?

    It probably won't help but I would reset your pram and nvram:

    And you could also (after that) shut down your mac, press the power button, keep it pressed (like 30/20 seconds) until it start for the second time (it will start when you press it, then when you keep it pressed it will turn off after a while and turn on again, so keep it pressed all the time).

    This might, might help.

    Did you try mirroring it? I had a similar problem and mirroring fixed mine.

    I don't mean to be smart, but are you on the correct input with the TV?
