Troubleshooting 1 red light Xbox360
Here is an explanation and a few suggestions on how to take care of the 1 red light problem with your Xbox 360.
The 1 red light error can occur on your Xbox because of a hardware failure or an accessory that is attached to your Xbox has been damaged.
Check your TV screen if you have an error code other than E74 or a blank screen there may be something wrong with one of your accessories or the HDD.
First – Turn of your Xbox and try unplugging your power and AV cable. If that does not work start unplugging your accessories like a memory card or wireless adapter or controller and restart your console after everything you unplug. If you are still getting the red light after unplugging everything take your HDD off and turn your console back on. Hopefully these suggestions have taken care of your problem but if not keep reading.
Now if none of the suggestions above took care of your problem or you have the error code E74 on your screen then you have a general hardware failure that was most likely caused by an overheating problem. But the good news is this can be repaired. You could send your console back to Microsoft, if you are under warranty they will take care of the problem for free, but if your Xbox 360 is more than 3 years old it will cost you about $140 to send it back.
I personally did not want to spend $140 to get a refurbished Xbox back from Microsoft I figured if I could not fix it I would just buy a new one. So I found a guide online that promised I could fix my Xbox in just a few hours or I could get my money back guaranteed. This guide showed me everything I needed to know to do the modification so my Xbox would not over heat anymore and the connection between the CPU and GPU chips and the mother board would reconnect. This mod was so easy to do and it worked. It did take me more than an hour and I did have to spend about $5 at the hardware store for some screws and washers. My Xbox 360 has been running like a champ ever since.
