Having problems with your Acer Extensa 5420-5687 Notebook ?

The screen on my acer extensa 5420 went black how can I trouble shoot to see what it is?


Answers :

Good day sir/maam, when your LCD becomes black, the backlight of the LCD screen just went bad. this is caused by the failure of the inverter circuit board and/or lamp, at this point you don't have much choice but to bring it to your dealer for possible inverter replacement, at the moment if you want to see your display, you can plug in an external monitor temporarily. you can activate it by pressing Fn + (locate on your keyboard a picture of a monitor with the same color as your Fn key). hope this helps.
