Xbox 360 no work

check the audio cables

try it in another tv with av cable
if u are using hdmi cable try changing the existing cable

if it works in another tv , go changing the setting in the displaysettings and video settiing

it is prolly an internal problem. have to tried connecting the componet cables?

call microsft. im sick of people asking about there 360 or ps3 shutting down not working dvd player not working..well what can we do here. nothing we dont have the ability to fix problems that have no solution. Call the person who made ur Xbox 360 microsoft ps3 sony and ask them cause we have no way of helping on these dumb subjects

It needs to be fixed, the right way.

If it's still under warranty, microsoft.

If not most shops and dudes on craigslist do it for $40.

Or you can go diy for about $10-15

I've seen this symptom before. Try removing the external hard-drive and see if the picture comes back. Another cause could be the video resolution setting. If the Xbox video resolution is set higher than your TV can display you will get a blank picture with sound. Try reducing the Xbox resolution if the hard-drive trick doesn't work.

your graphics processor IC chip needs its solder joints reflowing, and the heatsink re securing.

This will solve the problem.
