Part description & Part number

ASSY COVER P-LAMP PJ(E23); L3 SERVICE ,PH => BP96-00608A

1. To determine if DMD-PCB is the problem, listen the color wheel noise, during star-up procedure.  This should be heard within 20 seconds after pressing the Power button.  The loudness of the color wheel starting up is greatly reduced in this chassis as compared to previous versions, so you have to listen it closely.  
2. If the color wheel is not turning ON, this is caused by the DMD board.  
3. If the color wheel is operating, then the problem will be with either the Lamp of Ballast.
