I have a newer macbook pro and am trying to connect it to my Sony Wega TV (its from 04). I am using a mini display to dvi adapter then a dvi to hdmi cable. I have gotten the screen to work twice out of a handful of times and both times the picture lasted about 2 mins then went black and I could not get the picture to come back. Does anyone know what is going on and if possible how I could make this work?? Thank you.
