Having problems with your Gateway 450SX4 Notebook ?

Gateway 450sx4 I have a Gateway 450sx4 and it stopped showing the screen this morning, like it's all black but windows does start up, should i use FN and adjust brightness?" or maybe its a power problem? any help would do, thanks a million and god bless you all


Answers :

Yes you should try ito adjust the brightness.
\015\012Can you see a slight image on the LCD, screen this indicates a backlight problem?
\015\012You can connect an external monitor to the video connector on the laptop, then boot it up and see if the is a display on the external monitor. You may have to press the blue Fn + one of the Function key so you can switch the video output to the external monitor. If you get an image on the external monitor then the video card is OK and the fault is with the LCD backlight. This could be a faulty inverter that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty, 80% of the time it is the CCFL lamp that is faulty.
\015\012The inverter is easy to replace, the CCFL lamp requires a lot more work and requires soldering skills.
