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 baclight 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? Thanks you!
Roger WE really do not have enough information. It’ll help if you can tell us where you are measuring your voltage and check the voltage on Q9701 and L9701. Also, let us know if you measured/checked any other components or if you are assuming that they are in good working condition.
