MacPro6,1 No HDMI Video

Need some help guys,

Got a MacPro6,1 and have been connecting to my Sharp 90" TV for months, until today. I am able to Screen Share from my MacBook and the display preference knows the Sharp is connected, but I'm getting no output (audio or video). Here's what I've tried so far, with no result:

1) replace cable & verified cable seating properly

2) Tried different monitor (Sharp 70" TV)

3) Reset PRAM & SMC

4) Tried different HDMI port on TV

The MacPro is under warranty, but the nearest Apple Service is 40miles away. Any other ideas or things to try, before I disconnect and head over tomorrow?

Is this the only monitor you are using? What are the others, if any?

I Have a Sharp 70" TV as I mentioned. I don't have any other monitors to use

Does anything show during bootup?

If not that would indicate a hardware problem and thus a trip to the Apple store is in order.

Update...I took an HDMI to Thunderbolt adapter and I've got video working through it. I assume that something happened to the HDMI port 0 and I'll take it in for warranty service, but at least I know the TV and processor aspects are good. Not sure what could have happened to the port?
