If you can see that the lamp turns ON and you still dont have a image, most probably your DLP chip is bad, this is a very well known issue with Samsung's. Please check the following info:

After reading this you will comprehend that the DLP chip stops working and all of the micro-mirrors are on the OFF position.

The last picture on this link shows you the enclosure of the DMD board

Apparently the part # of the DMD board is BP94-02217B

I couldn't found the DLP chip with our sponsors, they have the light engine
