If your Xbox 360 has quit functioning and you are going through the 3 red Ring(s) error don’t panic, there is hope. With some simple tools and a nice repair manual you can perform the Xbox 360 Fix.
You will need a set of torx screwdrivers, If you don’t have a set you can scoop up a low priced set at your neighborly hardware store.
The 3 Red light error means that there is a console hardware failure. The 1st thing you want to try is to dis-connect everything and let your system sit for 20 minutes unplugged from the power. Re-connect everything in and try it another time, If you are still getting the error take out the HD and re hook it. more often than not they get loose and you get a bad hookup.
If that quick fix method did not fix it you will have to pop it up at this point. The most frequent failures are no video or disks will be read . Both can be repaired fairly hurriedly.
If you have no video showing you can try a new similar video cable, borrow a friends cable cord if you do not have an alternative one. If you still have no video but sound is functioning you will have to check the soldering connections on the main board for the video cord. Read the repair manual before attempting this or any other internal repairs.
If your gaming system is not reading the disks or getting disk errors make sure your disks are clean. After that you may have to replace the DVD drive or if you have the skills you can remove the DVD drive and replace just the pick up assembly. This is a lot cheaper than replacing the entire drive. Again consult the Xbox 360 Repair manual before attempting this.
Your other option is to send your console off to Microsoft and Wait. Nothing worse than having Halo 3 and not being able to play it. I prefer to do my own mods and Xbox 360 Repair.
