Samsung DLP TV H Series - White/blue blotches

Good afternoon,

The other day, the lamp on my Samsung HLP TV (H-T5076S) went out. I replaced the lamp today with a new Samsung lamp. After installing the new lamp, these white-bluish blotches showed up on various parts of the screen. They are persistent through different inputs.

I removed the new lamp and used compressed air to ensure there was no dust on it or the color wheel. The blotches still persist. I have attached an image of these blotches for your review. If you know of any possible causes or troubleshooting, I would appreciate your feedback. Thank you.

  1. I believe the cause is dust on the innermost lens of the projector. I was able to get rid of most of it through a thorough cleaning. I'll have to do it again tomorrow, though, since instead of a few big blotches there are now many tiny ones and the image is out of focus. Lovely.
