I do not know what model it is. But it is 73 inches wide and about 4 feet high. I want to play online with my xbox 360. I connected it to the front of the TV where it says INPUT 3 but when I press input on my remote, these options showup. CABLE-1, VCR, SAT, CABLE, DVD, CARD-1, CARD-2, CARD-3, CARD-4, TV DISC, ZOMPUTER and CAMCORD. I have selected all of them but not one will showup with my xbox dashboard. I have checked if the chord was on TV and not HDTV. Please help because i just bought two 3 xbox live month cards.
