Thinkpad Inverter Blues

  1. Had a customer call me with an IBM G40 laptop with issues.

    Faintly see the graphics on the LCD screen and no back-lighting. I popped the trim on the LCD and checked voltage out of the inverter, nothing. I did notice that the LCD will light for just about 1 second when power is 1st applied to the inverter so that rules out a bad panel.

    Has anyone ran across such symptoms on LCD inverters? I guess I can swap out a $26 inverter & see if it cures the problem.
