backlit keyboard not working- XPS 15 L502

I have recently replaced my laptop's bezel. Since then backlit is not working even though the settings are correct. Could this issue be due to bezel replacement. If yes, please suggest how to resolve it

RE: backlit keyboard not working- XPS 15 L502

I assume that removed both the keyboard and palm rest first to remove the LCD assembly and finally the LCD bezel. I would go back and check the keyboard and make sure that both the keyboard data and back lite cables are connected correctly. The manual doesn't show a back lit keyboard, but on back lit keyboards there are two cables that will need to be connected.
