Consoles dont break TV's... theres probebly just a loose cable somewhere. The thing with HDMI is they get loose real easy, so i'd suggest leaving all your gear on standby, tighten all cables to the TV and to the PS3, DVD, etc.. and try it then.
Also try changing channels.. sometimes the TV itself gets stuck on which channel you actually want and if you change it it wont change at all - just a blank screen. So try changing channels, turning the TV off, and repeating just to see if you get a picture on a known station.
