The lamp may need to be replaced. You will likely have to contact a repair tech, or look online for a new lamp if you are comfortable replacing it yourself.

With labor, an in-home call for lamp replacement can run between $250-500. Sometimes more depending on the service charges; but if you push around $500, I would put it towards a new TV.
