No but they will not repair it for free.
You can always visit the offical site of Microsoft/Xbox www.xbox.com If your warranty is still up they'll repair it for free.
you can send out your xbox 360 to Microsoft and have them fix it if you still got the warranty if you don't, it will cst you about 150$ to repair it with them
It depends Microsoft will repair somethings for free as long as your warranty sticker is still intact but otherwise we need to know what exactly is wrong with it.
It depends on wether or not it is still in warranty. If it's still in its 3 year RRoD warranty period, Microsoft will usually repair it for free, or send you a refurbished console. If its warranty period has expired, or if the warranty sticker has been removed or damaged, you will need to pay for a repair or refurbished console.
No, Xbox does not repair cosmetic damage.
If it is under warranty no.
No they only repair non opened xbox's trust me I tried
Contact Microsoft for help, especially if your XBox is still under warranty
Not without modding which is frowned upon by Microsoft and voids your xbox warranty.
Use the towel trick. Search it on youtube but only do this if your xbox 360 is out of warranty. If it isin't out of warranty, then send it to Microsoft.
There are some guides on the internet that assist people on how to repair their Xbox for free or without spending too much money. The Xbox official website and Microsoft have repair support for an Xbox.
