Our grandson has managed to get past the password to keep him from playing xbox 360. Is there some way to set one he cannot beat?

When you beat the game, go back to the missions and play them on FPS mode. This includes infinite ammo.

Hello
You can reset your password for xbox live as well as view other help topics on the live site. I have linked it below for your convenience.

Good luck!

Do not move the xbox 360 while the disc is inside and playing. Try not to stand the unit vertically just do it horizontally.

I've managed to come across this from someone who called microsoft with the same problem (it seems quite common)
Go into settings Console settings Then device settings (The one with the blue screen)
Then go:
left trigger, right trigger, x, y, left bumper, right bumper, left with left stick, up with left stick, right with left stick, x

If you have trouble use the pad instead of stick, but I could only get the stick to work..

I hope that helps
Regards

Does it say things like, Searching for match? When I first started playing it did that alot. But eventually you get into a game. And you must beat the Campaign to be able to play Nazi Zombies.

From the XBox website:


Managing Xbox LIVE Activity
Xbox LIVE Controls come into play only when you take Xbox 360 online, and they're linked to a child's profile and gamertag. When an Xbox LIVE account is created, the service asks for the member’s age to determine whether to apply Family Settings to that account.
Parents are also required to create or use an existing Windows Live ID. The Windows Live ID is associated with the child’s Xbox LIVE account and protects the settings from being changed later by the child. To change a child’s settings, first select the child’s account name and connect to Xbox LIVE. Once signed in, enter your Windows Live ID password to unlock the settings.
To see these controls, go to My Xbox, open System Settings, then selectFamily Settings, Xbox LIVE Controls.

One red light means either the hard drive isn't connected properly, or the video cable isn't connected properly, or is damaged.
Check the hard drive, and the video connection to ensure they're in there tight.

The xbox 360 wirless controller has very little lag that you would not be able to notice i would suggest just getting the controller and if u want u can also get a xbox 360 controller that is wired.

oh okay, tell him to check the connection of his a/v cable. possible causes could be that the cord isn't securely connected to the system at the back.

also, be sure that the switch on the end of the cable is set to either a/v or component (high definition R G B) depending on which one he's using! i hope that helps =)
