XBOX will not boot.

[mk7_ln52a]

I baught an xbox from a thrift store for $3 and when it tries to start a screen pops up and says 'service required. Call customer suport' in many languages and the number 12 is in the top left hand corner.  It did start up once but I turned it off and imediatly turned it on again but the same problem as above.  Is there any way to fix this problem myself?

error 12 - kernel - DVD parameters (PIO/DMA)
Same as error 10, only not very common.

error 10 - kernel - DVD timeout

Actually its almost the same as error 6/7/8. But also make sure the yellow cables are properly connected to the motherboard and the dvd drive.

1. Make sure ide cables are connected good.
2. Make sure the yellow cables are good and properly connected.
3. Still no succes? Try another dvd drive of which you are sure it is working.
