Projection lamp nearing end of life replace lamp still coming on


Along with the instructions for the lamp installation, you should have revceived instructions on how to reset the lamp counter. If not, this operation is listed in the owner's manual. If you can not locate that manual, please confirm your model number and I will post the instructions. Since the counter has not been reset, the TV will continue to show the "error" message.
