Video - Dell Display Inverter Replacement Tutorial

By Parts-People

BTH Webmaster message: If you turn on your laptop and the screen is dark but you can barely make out something on the screen then your back light has failed. The backlight is a fluorescent bulb. Fluorescent lights need a high AC voltage to operate. A circuit board inside the laptop called the inverter circuit takes the lower DC voltage from the laptop battery and converts it to a higher AC to voltage the fluorescent back light. It's common for these inverter circuits to fail. This video shows you step-by-step how to disassemble the LCD display and replace that inverter circuit board.

Warning: Avoid static discharge by grounding yourself using a wrist strap or by touching a bare metal surface like a connector on the back of the laptop and remove all of the power including the battery and power adapter.

Make sure all data is backed up before removing or replacing your hard drive. Laptop hard drives are very sensitive and can be damaged easily. Handle with care. Performong your own repairs may void your warranty.
