the new projection lamp come in as request and within the estimate delivery date . I install the lamp but have difficulty get a picture from the tv so I call technical support at Sony and they walk I through the issue . there be a door on the side of the tv in which the lamp be insert . if that door be not shut a certain way , there be a sensor that will not allow the tv to turn on . after that the tv work just fine . the lamp be a great deal and I definitely would do this again .
