Hi there happy to help.
Try the following to determine if the problem is the receiver or the Blue Ray.
Connect the Blue Ray directly to the TV via HDMI. Unplug the HDMI connection from the receiver to the TV, and use this port.
If your get good sound and video, the problem is the receiver. If not(which is what I suspect will happen) problem is with the Blue Ray.
Try taking the blue ray to the TV directly now with Component video and optical audio. Does this work? If so, then the issue is the HDMI output on your Blue Ray is not working.
Hope this helps,
