Yea HDMI works.
The picture actually came on from my cable box for a second then went out again. I dont know if that helps determine the problem or not.
If you used the XBOX cable for your testing is the switch in the right position per weirdlookinguy's post above? If so that might be the problem. Have you tried different Component cables?
If the Cable Box on Component gave you a picture for only a second before going black, and the XBOX did not even give you a picture, it does sound like a problem with the input board inside the TV. If you also connected the red/white audio cables along with the 3 Component Video cables and got no sound from either device then that's even more evidence that the inputs are bad.
Connect a working DVD player to the Component inputs and if you still don't get a picture or sound, and you're absolutely positive that you've connected the 5 Component cables correctly (Red/Blue/Green for Video and Red/White for Audio) then you'll have to have the set repaired or replaced.
