Help! S350 will not display . . .

[gatorstang]

My Sony BR player will not display a movie. The audio signal is being sent to my amp - I hear the movie menu music. The HDMI input jack is fine - I switched my HDMI cable from another source over to this jack and I viewed cable.
So, it's not the disc (tried several), it's not the TV, and I'm getting audio out.
When I power off, then back on, I get the Sony BRP screen, but then it goes black when autoplay starts the movie. The unit was one year old last month.

I figured there's a thread buried in here somewhere on this issue, but couldn't find one with a quick search.

Thanks for any help!
