Xbox 360’s E74 Error
This is what summer is really meant for: video games. You can feel all your troubles melt away as you and your buds trash talk over who is winning in the Halo deathmatch. Ah yes, this is truly the purpose of su–the TV goes blank. Then some type of message comes onto the screen. “What is this?!” you yell at your friends, but they are innocent. This is not a trick, your Xbox has E74.
You’re definitely not alone. E74 has shown up on thousands of TVs across the world. This error message is joined by one red light in the fourth player spot around your Xbox’s “on” button, and a black screen with a simple sentence in a bunch of not so simple languages. If you’ve got E74, you’ll know–it says it right there on the screen!
Of the different languages the message is written in, the English words should say something like “E74 error, call Microsoft customer support.” If you do that, call customer support, you’ll end up on an automated answering machine. Navigating through all that, eventually you’ll be told your console is experiencing a hardware failure. Okay, but now what? Now we need to figure out what is causing this to happen.
In some cases, this problem actually doesn’t originate from something inside the Xbox going bad. It could be that the AV cable, or some other cord, just isn’t plugged in, or not plugged in well enough. Obviously the smart thing to do would be check this; yank out all the cords and put them all back in. Turn on your Xbox again, and see if anything changed.
Also, see if you can get your hands on another AV cable. It could be that the cable itself is broken, and it’s causing your 360 to think the problem is much worse than it really needs to be. Try asking for a buddy’s, and see whether or not your Xbox works with that one. This isn’t terribly common, but worth checking. If you aren’t able to borrow one, however, I wouldn’t go out and buy one.
If your E74 still hasn’t gone away, there’s one more thing to check–separable components. Once again, turn off your console. Then, keeping the cords in, take off the hard drive, and the controllers, etc. Without them, turn on the console. If that annoying red light is still flashing, the E74 error originated inside the Xbox 360.
When this is the case, it is typically due to the HANA chip. The video scaler microchip doesn’t have to be broken. Most of the time, what is broken is its connection with the motherboard. This can happen if your Xbox overheats. That kind of heat often causes cracks or breaks in the solder holding it in place, stopping it from functioning normally. In roughly 1/10 cases, the HANA chip is fine, but the GPU has that same problem. Again, excessive heat can cause its connection with the rest of the console to become faulty, and result in E74.
