Step 1: Gathering the Tools and Materials
xbox 360 (Mine had the red rings)
LCD computer monitor (My dad got a broken one from work and I fixed it)
Now in case you don't have the money to buy a new xbox and monitor see if you can find an xbox with the red rings and a monitor that wont turn on. I fixed my monitor for about $5.00 and it works great (the problem was two bad capacitors).
Step 2: Taking Apart Your Xbox
Here is a link on how to do that:
Step 3: Fixing My Xbox
Reflow xbox 360 link:
Step 4: Working on the Monitor
I covered the bottom of each circuit board in electrical and then duct tape and put velcro on the back of the LCD and circuit boards and they held great. I also had to mod the power plug on the inverter because it would not fit in the case I had. You may or may not have to mod the power plug depending on what kind of case. You can also make your own case using wood or plastic.
On my power cord green=ground, white=brown, and blue =black.
Step 5: Fixing Your Monitor
Step 6: The Hard Part
Here is the link to turn your A/V component cable into VGA (I just used the pinout to solder it directly to the motherboard):
If you decide to solder it directly to your motherboard then you might have to some math if you look at pin 1 on the mother board the one next to it is 5 and then 9 it will say the numbers on the sides and the top and bottom row and you can just determine what the other pins are for yourself.
Sorry I forgot to take a picture of the motherboard after I soldered it.
Step 7: Now to Mount Your Monitor in Your Case
You may need some kind of foam to make it fit nice and snug.
Step 8: Conclusion
Well that's all I have for now, in the next step I will hopefully be covering mounting the xbox in the case and add the speakers. Until next time have fun with this and hopefully I will be able to finish my xbox 360 laptop soon.
Have fun and be careful!!! Electronics can be dangerous!!!
