Xbox360 E74 error

The E74 error seems to be related to video problems. It's occasionally caused by a faulty AV cord, but more often than not, the solder on the ANA/HANA (in HDMI models) scaling chip has come loose. In fact, many have reported creating a temporary fix by wrapping pennies in electrical tape and weighing the ANA/HANA down. (For the record, we're not suggesting you do that.) Before the error, the system usually starts showing graphical problems like lines across the screen or snow. It's accompanied by one red light in the lower right-hand quadrant.
