Gateway mx6426 lcd display

[nick2498]

I have been working on a friends laptop in which the LCD display doe
not work. In the process of trying to fix the problem I have replace
the LCD screen, the inverter board and the LCD harness (flex cable) an
I still get no display. I can plug the laptop into an external monito
and it works fine so the computer itself is okay, just no display. I'
at my wits end trying to figure out what else to do. Can someone ther
suggest anything?

Thanks in advance,
Nic

Hi Nick! Well two things come to mind.

1) If you use a flashlight or a strong light, if it is a backlight
problem... you should see the display very faintly. Things in white will
be easier to see. If you can see it, sounds like the lid switch is
stuck.

2) It is still possible I have heard to have a bad video card even if an
external monitor works. This model, I don't know if it has a separate
video card from the motherboard or not.

I have a GW desktop LCD that died on me some time ago due to
capacitors on the power supply board. They were a cheap Chinese brand
that died due to the fact that the industrial spies that stole the
formula for the capacitor electrolyte got the chemical formula wrong
(no I am NOT making this up).

I soldered in some new capacitors as described in that last link and
the LCD works like new now.
