1: check VB for LED supply !
2: check N301 pin 9 , if it is low, LED must light on
3: check R310 !

4: too Exaggerate at your post ! please check your style !

R310 is current for LED of LCD side !
and please read it very careful, "CHECK" at pin 9, when keypad side led light up, pin 9 of N301 must "low" too !
