Got one 5130c with light problem.............. no light in lcd and keypad.
I've tried changing LCD, LCD connector, light ic, 3 coils in light section, also 2 resistor near lcd jack............. still there no light in display and keypad.

Does anyone have any tested solution?????????/


Thanx.

if no voltage or only 4v on that coil (l3606)then remove light ic

if no active then rehot or replace betty ic......
but if pwm300 making switching volt(1.8) then post reply
