Okay, so you and your friends are playing your Xbox 360 and all of a sudden the screen your looking at starts showing some weird images.
The graphics look choppy and start turning into green swirly squares.
You think it might be an issue with the A/V cable cord, so you don't worry too much about it at first.
You turn off your system and check you A/V cables to make sure there properly plugged in.
When you turn back on your Xbox 360 you think everything should be fine, but a red light flashing on your console is saying otherwise.
Your Xbox 360 has a red light flashing and says E74 error.
You try calling 1-800-4myxbox and they were no help.
They tell you that they only fix Xbox consoles with the 3 red light error.
So what do you do? Most likely your E74 error is caused by a damaged chip near the A/V cable connection.
Getting yourself a new cable might help, but it's not a 100% guaranteed.
If you have switched out the A/V cables and your still suffering from this problem then you have to go inside the console and get to the hardware to fix it.
You can easily and cheaply accomplish this yourself by getting an Xbox 360 repair guide.
The repair guide will give you step by step instructions along with videos on how to fix the E74 error code permanently.
Fixing the E74 error code by yourself in your home is the quickest way to rid your Xbox of these problems, and an Xbox 360 repair guide will show you how.
The only other options you have to solving the E74 option is to buy a new Xbox 360 or send it to Microsoft.
