No Picture from my QNAP TS-251 NAS on my new receiver?

[Zman2k2]

Hey all.

Hoping someone here can help me. I recently got a Marantz NR 1504 receiver, and I hooked everything up to it that I have. Everything works, the cable box, XBoxOne, and the internet radio, but I can't get a picture from the NAS. It has an HDMI port on the back, and I use it to watch my blu-ray's. But, if I can't see anything, obviously that's not good. I leave the NAS on all the time, as I can download any movie to the NAS at any time, and even resetting or restarting the NAS has no effect. I have it connected to the Media Player HDMI of the receiver, so there should be no problems, but my TV is not getting a signal at all. The TV goes into auto shutdown mode if I leave the receiver on the Media Player setting too long. Has anyone come across something like this, and is there something I can do to kick it to make it work. I'm banging my head against a wall here.

Thanks.
