*HELP* Receiver not outputting video after power outage

[Higgs1]

Hello, I bought an Onkyo HT-S7200 HTIB in january, everything working great until today. We lost power for about 4 hours today and when power was returned everything works except my receiver. Its outputting audio fine, but I'm not getting any video. At first I thought it could be my tv, then I unplugged the output cable from the onkyo receiver to my ps3 & my cable box & both work fine, so now i'm pretty sure its the receiver.

It was not powered on and all my equipment is run through a surge protecter. I can't get any video from the receiver to appear on my tv, no menus nothing. Any one have any idea what it could be? Im under warranty for 2 years so it shouldn't be an issue I'm just curious if its just a stupid setting that may have gotten reset and can't seem to figure it out.

Any and all help is greatly appreciated.

For reference I have my ps3 & cable box connected to my receiver via HDMI cables & then the receiver hooked to my TV with an HDMI cable. All audio is working fine, video is my only issue.
