The E74 error is caused by the scaler chip at the back of the console taking too much heat. To fix it you need to stop the heat build up.

You can do this yourself using a good guide that will show you how to fix it with household items or you can send it in and they will fix it for you.

This is what the error will be if you have a light bottom right of the console.

this means that your scaler chip on your 360 is damaged, or you over heated it. try doing the towel trick, which is wrapping a towel around your xbox and over heating it, thus melting the scaler chip down to your motherboard, or turn it in for repair if you don't want to do that. i recommend personal repair.

E74: AV cable error... There is a problem with the AV cable, try using a different AV cable. If the cable is known to be working then there is a 90% chance it's a scaler chip problem (the "ANA" or "HANA" chip connected directly to the AV cable) in rare cases it is the GPU.

This usually means something is wrong with the graphics scaler. You'll eventually have to send your xbox in to have it fixed, and I believe it is covered under a one year warrenty.

E74 is an error with your AV cable and or your GPU / Scaler chip. If you can swap out your AV cable to see if that works if not you will have to contact MS, as there is no quick fix for this error if your cables dont work. Hope this helps.
