If your Xbox 360 has quit working and you are having the III red Ring problem don’t panic, there is hope. With some easy to find tools and a reliable fix manual you can perform the Xbox 360 Fix.
You will need a pack of torx screwdrivers, If you don’t have a pack you can pick up a low cost set at your local hardware store.
The III Red light(s) problem means there is a general hardware failure. 1st thing you want to attempt is to unplug everything and let your unit sit for 20 minutes unplugged from the power. Replug everything in and attempt it another time, If you’re still going to get the problem take out the HD and re hook it. It is quite common that they get loose and you get a bad hookup.
If that quick fix method didnt repair it you will need to pop it up at this point. The most frequent failures are no video or disks will be read . Both the video and the game disks can be repaired fairly easily.
If you have no visual you can try a different video cord, borrow a friends cable cord if you do not have another one. If you still have no video but sound is working you will need to check the soldering connections on the main board for the video cord. Consult the manual before attempting this or any other internal repairs.
If your Xbox 360 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 swapping the whole drive. Again read the fix manual before attempting this.
Your other choice is to send your console off to Microsoft and Wait. Nothing worse than having Halo 3 and not being able to play it. I rather to do my own mods and Xbox 360 Repair. The console unit is very similar to your home computer, it is actually a small computer. With a little patience anyone can learn how to do there own repairs.
