Help Accelerometer dead

[Quentin0602]

HI guys, i have looked everywhere so i ll try here maybe you can help...
My accelerometer is not working, i have the samsung galaxy ace s5830 and the autorotation is not working anymore, when i tried the sensor test it seems like its not working, i have tried hard reset already, my autorotation is on and when i try to calibrate the ball doesnt move, it stays in the center...
thank you, hope you can help...

please guys...its driving me crazy............
I've downloaded the logcat app and it writes in red:
E/SensorManager( 181) : +__poll_activate: handle=0 enabled=1
:ERROR Sensor Input doesnt not open events_fd=232 accel_fd=-1
:cannot find devnode accelerometer_sensor
and a lot of other things which look bad......
