Can you replace backlight lamp CCFL in your laptop LCD screen?

Yes, you can replace the backlight lamp aka CCFL in your laptop but it's not easy.

You'll have to take apart the laptop display panel, remove the LCD screen and then disassemble the LCD screen. This project my take a few hours and if you have no experience you can damage the screen.

If the backlight lamp is bad I would recommend replacing the hole screen.

Instructions for removing the screen you can find in the laptop service manual.

A new screen you can find on the Internet if you search by the part number. The part number is usually located on the back of the LCD screen.
