V10 issue any suggestions?

[Jamey]

Thanks for looking. Ive been installing chips since the ps2's came out and the chips were ready.

I just installed a messiah pro 2 chip in 2 different version 10's. One was mine and one was for a friend. My friends just up and died on him with only 2 months of use on it. Mine has worked flawlessly.

I tried taking my laser and fitting it into his with no luck. And I took his laser and puting it in his and that didnt work either. THe lasers physicly look a little different but I thought they should work.

Anybod got any ideas what could be the problem? I also removed the modchip before these tests on his ps2. Thanks for any help you might be able to give me,
