Having problems with your PC Laptops ?

Led lights up no display. perfect thru vga Toshiba A15-S127


Answers :

Hold down the FN key and as your doing that push the F5 key and that will toggle between the external monitor and the lcd. the LCD should light up at this point.

If it does then problem solved. If not then its either going to be a problem with the LCD backlight going bad which means the lcd would need to be replaced, the inverter which is located underneath the lcd inside of the front bezel not putting out the correct voltage or the connector on the motherboard not putting out the voltage required to light up the lcd.


If you can get a display through an external monitor but your LCD display won't show anything, you have one of two conditions:
You have hit the Fn and special function key that toggles the display to go to the external monitor. In that case, hit that key combination again to see if you can toggle the display back to your laptop.
The other thing would be an LCD display that has gone bad. You can rule out the video card, as it will put video out to the external port.
