    Toshiba Satellite M35, LA-2462 Power on but No Display

    The typical symptom for this laptop, it reacts on power button but the video is missing on the screen. If the current consumption on the external power supply is between 0.3A and 0.4A, this failure is most probably caused by a bad solder joint under the PU13 IC chip (MAX1987).

    After resoldering it, the video is getting back.
