laptop display (backlight /inverter)

By Beginner9 ·
Hi all

I have an acer aspire 5100 15.4inch laptop.Its display is very dim, I hardly see the image. screen is light black in color :)I have connected the laptop to the external monitor using VGA, its working fine.

I opened the lcd. I think the problem is with the inverter or the backlight.

1)How do i check if the problem is with the inverter or backlight?

Its easy job to change inverter. But replacing the backlight is very tough for me in shops they charge ?80 - ?90 where the back light costs around ?10. I cant afford.

any help will be appericiated

Probably the backlight

It's most likely your backlight. If you can see an image and it stays consistently dim, it's your backlight.

Inverter symptoms are usually no image, colors changing wildly, and others.

Some LCD monitors that backlights aren't as bad as others to change, but I've not changed on in an acer laptop before.

Many of them offer on-line instructions and demo's on replacing the components they sell.
