No picture but sound

i think u hav some problem with the visual mode and u can make sure whether your settings r normal..then also it doesnt work anymore u can try this site to solve the problem

sounds like u hav an air bubble in radiator from cold take radiator top off then rev engine to see if it bubbles if it does do this till it stops bubbling then top up wen it cools down then put radiator cap on then check heater gets hot wen warm then this is solved

This might just be a bad HD/AV cable. I would recommend that you borrow and friends and try the cable first...well actually the first step would be to make sure they are in correctly & tightened up;)

just did one of those 1 hour ago
running great now
X clamp mod , it fixes so many problems.

Its either a defective video cord or a bad connection in unit where video data connects to binding post which the video cord plugs into back of machine.

if playing on a normal tv be sure to check if you accidently turned your cord on hd not normal if it is on hd ul hear the game but wont beable to see it

make sure the switch at the back of xbox is on tv or hd, whatever you use.

1 leads are in the wrong way i hav had the same problem move ur leads around or go and buy a hd lead i pad 9.99 from blockbusters for a hd lead its worth a try
