I'm a new MAC owner and slowly learning 
An apple consultant at Best Buy sold me the mini display port to VGA adapter, VGA display cable, and stereo audio cable. When all set up, the volume comes through the TV very very low and the only picture I get is the purple light in outerspace MacBook picture, not the movie playing on my macbook. Please help me, I have no idea how to fix this. Thanks!
