The E74/E6x/E4x/E8x are famous error codes that have
plagued many Xbox 360 gamers. This error codes will be displayed on
your screen, each indicating different problem with your Xbox 360. It's
usually defined by the single red light or 1 Red Light Error lit up at
lower right quadrant on the Red Ring of Light on your Xbox 360 console. E74: There is high
chance it's a scaler chip problem (the "ANA" or "HANA" chip near the AV
cable connection) it can also be caused by a faulty AV cable so check
that first. In some cases it is a problem with the GPU and may be
repairable by using the Xbox 360 Repair Guide. Xbox 360 E74 error has
reported to increasing a lot for the newer Xbox 360 version.

A single flashing light can mean a hardware failure. Did you get an error code? EXX where XX is a number...like 74 for instance? Please, let me know, and try this.
Power off the system and unplug everything from it..controllers, memory cards, av connection, power cord, and hard drive. Also unplug power cord from socket and the short cord from the power brick. Then reattach everything making sure the connections are firm and power back on your system. If this did not resolve the problem.
the e74 error is a problem with your AV cable or the HANA scaler chip on the board, but the one red flashing light means you have a general hardware failure in others words its buggered, luckily this error has a 3 year free replacement warranty on it so just send it back to microsoft for a free replacement
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
The single Red Light and the E74 error code means that there is a I/0 Hardware Error. This error code can mean a few things but the most common is that there is a problem with the scalar chip.
The Error could also indicate a problem with the AV cable so you may want to check this first before attempting a repair.
Microsoft cover this in their 3 Year warranty so if your console is not modded and in its 3 Year warranty contact them first.
The error can be sometimes be fixed with the X-clamp fix but this is a rare working fix.
The cause of E-74 with one red light Error might be overheating of your console
and for avoiding such error in future you need to put your machine at an open
space. Ensure that it is placed near the window or you can also make some
external arrangement for cooling of console such as cooling the machine through
a pedestal fan. But as your Xbox already have E74 with one red light Problem
which can be solved by only repairing it, no other alternative. Either you
can send your Xbox to Microsoft (Please note that microsoft is no longer
providing extended warranty for E74 with one red lightError) and wait for 3-4
weeks. If you don't want to wait for a month, you can also fix E74 with one red
light problem with the help of this DIY Video, the guide will explain step by
step approach to fix the problem. Choice is yours.

There is high chance it's a scaler chip problem (the "ANA" or "HANA"
chip near the AV cable connection) it can also be caused by a faulty AV
cable so check that first. In some cases it is a problem with the GPU
and may be repairable by doing the x-clamp replacement. Also try this take the AV cable, plug it out and plug it in, if it still
doesn't work unplug it, wipe the metal part with a soft cloth then
plug it in. That might help.
