Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

You may have to troubleshoot the bulb's socket with an electronic volt meter, to find out what voltage is missing that would otherwise turn the bulb On.

It might be the ground wire, or it could be the positive voltage that powers the bulb, either one.

What color is the loose wire, that looks as if it had come unplugged? green generally means Ground, though there are some exceptions.
