Re: Toshiba Satellite LED screen no backlight

Hi, I just wanted to say: thank you. This thread set me off in the right way. And I just got an LCD panel backlight back to life in a mysterious way. I hope to share my experience here.

First, thanks for this thread. I have a faulty Toshiba L500-128 with la-4981p mother board that has no backlight after a water damage incident (glass of drinking water). Ordered a new inverter, still nothing.

I've measured +3.3v on pin 40 (BKOFF), +19 on 33-35-37-39, 0v on 9 (DAC_BRIG), but only 0.1v on pin 11 (INVT_PWM)....
