So I just purchased a broken Jtagged xbox 360 with the 3 rrod from ebay. i plugged it in and it turned on the the red ring started with the lower right light blinking for 5 seconds or so then only the 2 left wonts would blink. i pushed down on the heatsinks and something clicked now it turns on and the green center light blinks repeatedly, it doesnt shut itself off or boot up, tv is set up properly and all wiring is fine, the power brick light is green when on and amber when off. the dvd drive is gone, it came with a dvd drive chip though... however the same thing happens whether the drive chip is wired in or not or if i boot it up with the eject button. the actual Jtag wires have been removed (by the guy on Ebay) i've searched google and everything they say to do has not worked. somebody please help
