Xbox 360 - While setting up in menu the TV went black and msg. No Sync. Signal

Hey dude, I had this problem and found a solution on another website. Basically, I had either changed the display settings on my tv, or it had done it by itself or my new ps3 had done it or whatever, but to fix it I went into the TV menu, went to display options, on my tv it has something entitled 'Colour system' I changed that to PAL-60 and I now have colour, just to give you an idea of whether you have the same problem, try setting your x-box display to pal-50 and see if that shows colour (if it's easier to do), if it does then try then solution above! Hope it helps!

Maybe someone stepped on your cables try getting different cables.

For example if your tv is hd get a hdmi cable or buy another set of those cables.

Maybe it will help.

how to formating (sd) memory card n-gage QD????

check the console display settings. try 1080i or less depending on what your tv's capabilities are. If its 720, set the display for 720. Give this a try.

try to sync them with a plug and play they should stay synced even after you unplug them

Downloaded the updated firmware from the sharp website to a usb drive. Placed the drive in the TV and went to the update software option on the TV menu. Since the update, I no longer get the black-outs on the screen. I also put the resolution on the 360 back up to 1080p and it works great, even through the component cables.

You need to set the monitor up. I have a 42" LCD TV, and there is a menu where you can set the aspect ratio to 'Auto', 'Full Screen', or "4:3". I had a similar issue with my DVD player. I'm sure if you go through your monitor setup menu, you should be able to solve this problem.

Start the game and go into the options menu. There is an option to calibrate lag. Complete the instructions and the guitar will be synchronised with your TV.
If you mean how do you assign a guitar controller to the console, press the small button near the headphone port after pressing the guide button to turn the controller on, then press the small circuar button on the front of the console like you would with a regular 360 controller to assign the controller to the Xbox.

Hi there,

sounds like you have a graphics card problem with the xbox 360. possibly loose/damaged electrical connections between the GPU and the motherboard which has caused the xbox to not display a picture. with this being a Hardware problem i would suggest calling the Xbox customer support, numbers can be found on http://www.xbox.com/support call up the support team and explain your problem.

I believe that microsoft will ask you to send the Xbox direct to them so they can fix the problem for you, it shouldnt take long to correct !

hope this helps

I would check to make sure your video settings aren't set to PAL-60 by mistake. It might be easier to resolve if you could let us know what leads you have and where you've plugged them in to.
