820-2330 logic board! MacBook Pro 2008

テキスト:

Hello guys,
 
I have a weird problem on this 820-2330 logic board I’am working on, the backlight circuit only produced 14,4volts on lcd output. I replaced the baclijghtbaclight chip three times and still can’t get the boost circuit to work. All resistors are good around the chip and there is no broken traces anywhere. Can anyone shed some light on this problem?
