How to Replace Your Laptop's Backlight

Step 7Testing

Testing
Before going through the trouble of reassembly, reconnect your inverter and bulb and start up your machine. Does the bulb work? Allow it to stay on for a few minutes to make sure it doesn't overload the inverter (high pitched squealing). If everything is good -- continue forward. If the bulb does not light, check your solder joints and then check for connection issues. If that's good, check the bulb for cracks. Otherwise, there's a possibility you got a dead bulb.
