ps3 problem with sony wega kdf-e42a10 help going insane

I have a Sony Wega KDF-E42A10 and I'm trying to hook my ps3 up to it via hdmi. The ps3 is usually out in my living room but I want to move into my room so me and my gf have a dvd player in here as well. But I'm having issues. The hdmi cable is fine as it works in the living room through hdmi. The tv was working fine with my xbox 360 through hdmi about a year ago. I sold my xbox 360 no longer wanted it. The tv's hdmi input is video 6 i think says 6 on the back by hdmi in (i've skimmed them all while the ps3 was on and nothing). I reset the ps3 settings by holding down the power button when I turn it on. So it goes to lowest basic settings and nothing on video 6. It wont work if I hook up compsite and hdmi then switch the ps3 to hdmi settings and unplug the compsite. Im totally lost I dont know what to do and im like 95% sure the hdmi port on the tv is fine as I used it not to long ago. Only thing I can think of is some how the hdmi signal got shut off? If that's even possible and the users manual doesn't help that much unless I missed something. I have no Idea how to turn it back on looked through all of the tv settings and nothing if that's even whats wrong im so lost I'm going insane please help.

PS3 screen > Settings > Display Setting

And choose your HDMI cable at the lower two options.
