Mini 2440 with Win CE 6.0 cannot lit backlight after safe mode

Heloo, i just build custom run time image Windows Ce 6.0 and decide to
build kiosk mode with custom shell, i just did make boot and load my custom
shell, but after device enter safe mode ( lcd backlight goes turn off to
safe power), but when i try to touch screen it didnot lit the backlight
again!, please someone can help me with this problem.

appreciated thank you

ok i just solve the problem, main mistake is i did  not include power
management module with full option when i removed standard shell, so after
included it i just can resumed backlight. :)
