I had the same white spots issue as other posters on my HL-5076S X/XAA which is less than 2years old and we had just apid $250 for a new bulb.
I followed another posters advice to do online help chat - They tried to indicate my model issue was due to normal wear and tear but I was quite insistent that I wanted Executive Support escalation - see therad copied below.
Long and short of it is that they esaclated - gave me an escalation id and promised a call back from executive support within 48hrs from the chat which was saturday morning Oct 15th.
Executive support called on sunday and said they would provide one time free replacement of DLP chip and a technican from area would call within 48hrs to schedule.
Technican called Monday - repair scheduled today - they came and replaced chip in 20minutes and TV is as good as ne - NO Charge.
Thanks to all posters that helped me follow this course to get my fix for free as we were almost at the point of shelling out fro a new TV.
Best of luck to other unfortunate SAMSUNG owners!

Trish: This is a known problem with several hundred complaints on verious forumes and even a face book group
Trish: I would like an escalation number and the phone numberto executive support
Kristy: After extensive research and testing, Samsung has determined that on this particular model, the part failure is only due to normal wear and tear and not an epidemic issue.
Trish: well according to all the posts I read that is not the case. I even see posts as recentl as august to oct 2011 where the problem has been fixed free as a result of executive escalation on the same model and I want the same service
Kristy: I understand your concern, however we do not have any epidemic failures with the model you are using.
Kristy: Can I help you with anything else?
Trish: i understand that you are foillowing a script that you are provided as part of the service center and your response is exactly that of another agend in another service request transcript in a post that I have read this morning - none the less - the end result was that that customer was given an escalation number and the phone number to call for executive support
Trish: And I would like the same
Kristy: Please allow me to go through the inquiry.
Kristy: Thank you for holding.
Kristy: Would you mind holding a few minutes while I escalate the issue to the executive support?
Trish: No - I would very much like you to do that
