As with other electronics, there are several errors that may occur with your Xbox360. The following is a short list of some general errors that Xbox360 users experience. This is by no means a comprehensive list and I am sure there are many more errors that are not listed here. It should be noted that the suggestions listed here may or may not solve your problems, as you may be experiencing multiple errors.

The Uncommon E45 :

To the best of my knowledge the E45 error is not that common, however that does not mean it won’t or can’t happen to you. I have searched through many forums to see what the most common errors are and this appears to be one of the least common ones. If you are experiencing this problem it is most likely a problem concerning an update. Meaning, obviously something happened during the update process that didn’t go right. To fix it you will probably need to try re-updating you Xboc360. Try turning it off and then updating again when you turn it back on.

Problems with DVD Drive:
The E66, E65 and E64 errors are all errors that have to do with your DVD drive. This error is also not very common. If this happens to you and your warranty is still valid then I would suggest you return your Xbox360 to Microsoft and let them repair it for you. It most likely has something to do with the firmware.

Hard Drive Problems:

The E67 is a little bit different than the other three drive errors. It usually is cropped up more than it is not. If you are getting this error it most likely involves the internal hard drive or hard disk errors. You should probably contact the Xbox360 support to help you with this problem.

Memory Unit Problems:
If you having problems with the MU of the Xbox360 try turning it off, and then removing the MU. Then turn it back on and see if the error shows up again. If no error shows up then try putting the Memory Unit back into the Xbox360. Then run a couple of tests with the MU disconnected and connected. This will let you know if the problem is with the Memory Unit or something else.

E74: This is probably the most common error out of all of the errors on the Xbox360. The E74 is probably problem with the scalar chip. The scalar chip is by the AV cable connection on the inside of your console. It most likely has overheated. A simple fix to this problem is to disconnect any accessories and then turn your Xbox360 of for a couple of hours until it cools down.

You are enjoying a nice game of Halo and suddenly a screen begins to appear discolored or fuzzy.  Although you are hoping it is nothing more than the TV going fuzzy for a second, the game then freezes.  This is a common problem that every Xbox 360 gamer dreads.  However, there are a number of ways you can repair your Xbox 360 rather quickly.

An “E” error signifies when your Xbox 360 receives one red light in the bottom left hand corner.  Typically this is going to occur after your system has been re-booted.  After rebooting the system you will receive one red flashing light and an onscreen error of some sort.  These errors are signified by an “E” and two numbers.

If you are receiving an E67, E68 or an E69 error, these are hard try problems.  You can try to unplug your hard drive and play without it or you can attempt to reformat it.  If you are going to attempt to reformat it, make sure you have instructions to follow from online.  A general hardware error is going to be signified by an E73 message.  This can be caused by problems with the Ethernet or networking port.  If you do have an Ethernet cable plugged in, try playing without it to see if it is an issue with the cable.

The most common problem you will deal with is an E74.  The most common reason for this error is because the AV cable is installed incorrectly.  You can repair your Xbox 360 and solve this problem by disconnecting it and then reconnecting it.  If this is not the problem it may be because of a faulty ANA chip or a general hardware error related to your system overheating.
