Onkyo 606 menu/setup not dispaly + other issues

[statikcat]

So lately my Onkyo simply REFUSES to show me the setup page on my tv (Phillips 1080p). I just get the listings on the Onkyo itself. When I hit return to come out of settings my screen flickers like it thinks its working. I have unplugged and repowered both my tv and Onkyo. I have unhooked everything from my Onkyo except just the hdmi to my TV. This used to work.. then it started only working sometimes. Now my Wii simply gets no video either .. only audio and it IS setup correctly. My PC, PS3, and 360 are fine. I have been at this for hours tearing all my stuff apart. The only similarity between the Wii and the Onk menu is they are both SD. However, my cable box is also SD and it works fine. I also tried launching the setup page while the cable box was displaying. This is frustrating.. Any suggestions? I also factory reset my Onkyo and tried various display settings and hdmi on my TV.
