Toshiba Satellite L300 Black Screen Issue


Sep 11, 2016
I have toshiba satellite L 300 laptop. It worked fine on battery but on Power supply it used to trip time and again. I contacted local Laptop repair shop. They told that the problem was with Nec Tokin 0128 capacitor but they did not have it. So they tried to replace the capacitor on hit and trial basis from some other laptop. The laptop booted but the screen went black. After a few days the capacitor was replaced with Nec tokin 0128 capacitor which I bought online. But the problem still the screen neither glows on battery nor on power supply. They told that the mother board is not giving the required voltage for the screen to glow. The cable other connections were thoroughly checked but the problem persists. Kindly suggest.
