I have been using the Matrix chip for sometime now, and all of the sudden, the xbox will not play a game anymore. The chip inside is still showing a green light, but once a game is inserted, it turns on and off a few times, and the light blinks green and red.

Anyone else have this happen all of the sudden? I assume the chip worked itself loose, and moved, or maybe my xbox is slowly dying.

Thanks for any info...

Actually, without a game in the xbox, the drive bay will not even open, it just turns on and off, so I cannot even put a game in anymore. Chip still green though.

you need to reallign the chip.
the light you are getting is a false allignment light

Got it realligned, light is green, xbox lights are normal, but no games load. Could this possibly be a problem with the chip now? All lights look okay, but no games boot. I will probably re-program it, and then try again. Not sure how the bios could have got corrupted.

For what it's worth I had this problem before and was very close to throwing the xbox at the wall!

But I found the culprit in the end. In my case it wasent the alignment, because I knew I was aligning the chip right. It was the bios and the battery.

I used an older bios (IMHO don't use D6) and a brand new battery. Don't use an older battery even if there is power in it. Buy a new one and reflash the chip with a different bios, one that's been tried and tested.
When it finished flashing the bios, I alligned the chip, screwed it down, switched the mode, turned it on and hey presto it worked.

Best of luck

Just always use a colored BIOS, then you don't have to worry about the light on the matrix. If it boots up red/blue logo. You can tighten it and close it up.

i had the same problem and found out that even though the chip was solid green the alignment was still off got the colored bios and lined it up right and hadnot had any problems since

i had the same exact problem with my matrix and a f'd up bios, try getting evox d.6 bios it should fix things
