BLU RAY HDMI?????????????? - whats the best hdmi reciever to buy

I have a Sony model S350 for Christmas. I bought an HDMI cable and plugged into my audio receiver. I post on my TV HDMI 1. Then I changed the sound of the audio receiver or DVD. but when I changed the audio to the screen blank DVD. Later in standard cable plugged in to a Blu-ray. (Only the audio cable) and it worked. But I began to see the film and sees no difference. I have the visual configuration of HDMI. Do not change the audio settings. my audio system is an Onkyo. My TV is a Vizio 32 inch. (its 1080i or 720p)
I do not know what is wrong. blu ray think what I've seen nothing @ Best Buy.
