I have 2007 2.4ghz macbook, with mini dvi out. I have apple adapter that goes mini dvi to dvi, and I have cable that goes dvi to HDMI... But it is not working. when i connect it my macbook screen goes blue, wich is good, but nothing happens on TV. i have one more adapter that goes dvi to hdmi, and hdmi to hdmi cable, and that works... DOesn't make much sence to me...???
dvi to hdmi cable is not problem, it worked before and i have 3 diferent cables of same kind...

Please if you have any advice, contact me
