Ok so tried to turn on my 360 today and was greeted by no signal on the screen, the controller wouldnt sync to the console either. Visually the controller blinks all four lights constantly and the xbox has no flashing lights just the power light on. I dont use a hdmi cable just standard AV cable. Anyone know whats gone on or how/if its possible to fix. I tried the console on another tv and used a secondary Av cable to no joy and even connected the controller via the power cable so I know the problem is with the xbox, Any help would be appreciated.
