Backlight on keyboard not staying on, sensor retune?

[cpm1979]

I have the sony xperia x10 mini pro, the qwerty keyboard was working fine, i had the ear peace replaced,

but now qwerty keyboard backlight wont stay on for more than a second when im trying to use it,

so i know the lights are working no loose wire/connections

i've updated the software and factory reset, but still no change, im guessing the light sensor needs retuned/reset......

Is there a way of doing this?

Seems to be a hardware issue, you will have to replace the backlight
