I have a Sylvania TV (model number SRT2420p) and a Macbook Pro. I bought a Mini Displayport to DVI adapter, DVI to RCA, and connected the yellow RCA cord to the tv. In the "game" mode where the RCA cable should be recognized, nothing is happening. I changed the display to all the different display options, and still nothing is popping up on the tv. I changed the display to 1024x640, and restarted the mbp, nothing. The mac realizes it's plugged in because it flashes the blue screen when I put it in or out, and the mouse can go off of the screen. Is one of my adapters broken?
