Replacing light tunnel (instructions)
Hi, if you did not get help until now, i can send you step by step instructions and photos how to do it. I did several of these and it is not a big deal.But you will have to take apart a very sensitive optical device and if you are not confident that you can do it do not start this.bp67-00291a is the part number for the light tunnel.post a message here if you need that file with instructions

I had a similar issue with mine from the factory. There was a grey/black shadow in the upper left. Called for repair. The guy took off the circular access panel on the left back side and there was a fingerprint on the projection lense. He cleaned it and it disappeared. Sounds the same. Maybe touched the lense replacing the color wheel?

HLS5087 DLP - Samsung
You probably have a bad Light Tunnel. Samsung has a Tech bulliten and recall for this defect and might pay for the repair. Call 1-800-SAMSUNG and ask for the ECR Group and explain the symptom. If they resists to pay for repair mention the recall.
