Please Help Me!
 

1) Suddenly my X-Box changed to black and white mode on my television. I tried 3 cables until now and 5 TV’s. Is there something than I can do?
2) My X-Box’s DVD drive can’t read original disks (DVD movies or Games). What Can I Do?

I have the Matrix modchip installed.

Can Anyone help me?

Sounds like your mod has become disaligned. I've come across machines where they refuse to boot but usually they don't show anything on the screen.

Try realigning the mod and report back with results.

but the mysterious of the case is that everything works fine exept the black and white mode and refuse of the machine to read the original disks. alla my copys works great but black and white. is that means that the modchip works?
