I need a guide to fix my e74 error that is FREE. I looked on that page and at both lined websites. They require a purchase.

Not bad, just a quick brief and you could try but here:

It’s just like every other day, video games flying across your TV seemingly nonstop. Your Xbox 360 whirs silently as you scream at the top of your lungs at whatever game you are playing. But as you put in the third game for the day, something goes terribly wrong. That’s not the loading screen you see on the tube, it’s an E74 error.

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, “E74 System Error. Contact Xbox Customer Support.” There is no harm in doing exactly that, but there is little good either. The only thing you might learn from a conversation with their automated answering machine, is that your Xbox 360 has a general hardware failure. That means it doesn’t work–which you probably figured out by now.

Though, before we get ahead of ourselves, we have to check our bases. Sometimes this error occurs just because there is a faulty connection between the AV cable and the Xbox it’s plugged in to. If you’re feeling lucky, this is the only thing wrong. Here’s the easy way to check: power down your Xbox, then take all the cords and cables out. Plug them all into their proper places again, and hit the power button.

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.

Looks like some douchebag mod overstepped his boundaries and deleted my post, despite it being the only useful one.

Back on topic, try swapping the AV cables. If that doesn't work, you need to send it back in, period. You can live without your xbox for a week or two. It's not worth it to void your warranty trying ghetto fixes that most likely won't even work.

You should send it for repair if you can.
If you try to fix it you'll void the warranty and it'll probably not function properly.

If you really want a quick fix, buy another 360, it's never a bad idea to have a spare one
