FAQ
Q: There is no display ( or Dim Display) on my laptop screen but I still could see all the
icon on screen, What cause this problem?
A: The reason cause this problem could be defective backlight lamp or inverter
board. The easiest method to isolate the problem between backlight lamps or
inverter board would be connecting a good lamp to the inverter and turn on your
laptop computer, if lamp lights up, then the problem should be backlight lamp.
Otherwise, it could be inverter board. However, in some case, the defective
motherboard will cause the same symptom.

Q: My screen had been completely dimmed out though you could see the
screen was working if you used a flashlight. I ordered and installed the
MoniServ Inverter Board. The screen came back to life and was working
excellently - though a bit dim so I figured I will have to replace the light
itself before long.
Anyway, long story short: After about 8 hours of working, the screen
blanked out again. Just as before, I can see the screen is working if I use a
flashlight.
Now at this point it looks like I have to order the light anyway....... But.....
Since the screen went blank so soon, is it the light? Is it the inverter? Or
possibly something else? I know the Nvidia card is fine because it drives by
supplementary monitor with no issues. So the issues are entirely with the
laptop monitor/display.
A: As CCFL lamp is wearing out, it requires higher and higher striking voltage from
inverter, until it finally reach the point which overload the inverter and damaged it. Then,
You need to replace CCFL lamp and inverter at the same time.
