Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Carl, are the lights lit solid or are they blinking?
Have you tried fitting a replacement lamp?
As the lights are solid lit and the lamp light is not blinking, this indicates a problem with the power supply to the lamp - a component on the lamp's ballast power supply board has likely failed and the board will need to be replaced.
