When he opened it up and took off the optics, it was immediately clear what was causing my white spot.
He said this is common on all dlp's, everyone on this forum will get it and and should expect it. Luckily, it is easy to fix in about 1 hour, just remove the light engine, remove the shroud, remove the optics (4 screws) and you can reach into the light tube with a qtip and some non streaking cleaning solution.
Depending on your dust situation, you might have to clean this once per year. I've had my tv for 7 months and it needed cleaned, but we have lots of pets, so that doesn't help.
The tech said that if you are smokers and the dust builds up, the smokey dust stains all plastic lenses and stuff, and cleaning makes the non stained areas clean but the stained areas stick out worse than before, so they just don't clean lenses in houses that smoke, those lenses will need to be replaced.
The guy knew what he was doing, he was in and out and got my tv back to original condition. Now I know, twice a year or so, clean the dlp chip.

LOL, not really. I was answering what I thought was the question, something on the order of "is it worth it to have the halo fixed if it isn't that bad". So, I gave my $0.02. Maybe I said it in too many words, here is the shortened version: "I would not have fixed the halo if I didn't have a distinct and seperate issue that turned out to be dust on the dlp, however, since I had them come out to fix my seperate and distinct issue that turned out to be dust, I had them fix the halo while they were at it".
I agree that the light streaking up towards the white circle is not dust. I know where the DLP chip is, I watched the guy clean the dust off of it and asked him how I could do this myself, since he said dust on the DLP is a problem with all dlp's.
