Darker screen after replacing a samsung dlp lamp


DID YOU USE THE FOLLOWING LAMP
BP96-00826A (PHILIPS WRITTEN ON THE LAMP)? ALSO PLEASE CHECK THAT THE LAMP IS COMPLETELY SEATED OR IT WILL RESULT IN BRIGHTNESS ISSUES. THERE WAS ONE THAT I REPLACED THE LAMP IN AND I NOTICED THAT THE DIAL OPENING ON THE LAMP HOUSING WAS A BIT SMALL AND WOULD NOT ALLOW THE COMPLETE SEATING OF THE LAMP AND I HAD A DARK PICTURE AS A RESULT. I USED MY CORDLESS DRILL WITH THE PHILIPS HEAD STILL ATTACHED AND REAMED THE HOLE LARGER AND IT SOLVED THE PROBLEM.
HOPE THIS HELPS.

This is your Light Engine that is defective. They usually cost in excess of $700.00 to replace. Not the Lamp.
