Default [Q] HELP! I got a problem with touchscreen after flashing kernel

My screen is going unresponsive and I cant touch anything after I flash Alfs ICS.
I cant touch anything on the bottom of my screen. So, I cant unlock my screen.
I flash it back to Stock kernel but nothing changes.

I try to flash another kernel, and the same problem appear.

I use Service Test to check my screen.
See the picture below for the result.

Whats wrong with my screen?? Anyone help??
