So I thought, must be coming from the lamp, removed and cleaned that, spots are still there. Hmm, I guess this is coming from the convex lens? Does that sound right? I dunno. Is this something I can clean without destroying the geometry of the set? I don't really have or want a bowing issue. Also, the set now likes to alternate the brightness every second or so...very annoying. Sorry about the long post. If you've been there and done that, please spare me a little time. I've taken off the back lower panel, where do I go from there? Thank you in advance, you are my hero (in anticipation of having my issue resolved).

This is another thread I started.
long and short. I called someone, it turned out he didn't fix it. But I did see how to take it apart when he took off the back of the TV and slide out the projection tray which holds all the guts.
It's a matter of releasing all the wires and then unscrewing four screws which hold in the polarized glass. I cleaned the glass and then slide it out to access the convex mirror.
I DID NOT move the mirror from it's mount. I just used barley any pressure with a lens cleaning cloth to dust off the mirror.
DO NOT I REPEAT DO NOT move the mirror at all.
I had no adverse effects after putting everything back together.
If you do it, take your time and don't rush.
For everybody else. DO NOT USE COMPRESSED AIR to clean the back or inside of the TV. Don't make the same mistake we did. You will not like the results and will have to take the chance I did to clean it.
in the end, it worked out and the TV is actually like new again, but I would not want to have to do that to many times.
They really should have sealed that area from dust as I thought it was source screen grain. That's what it looks like until you see how much stuff is on the convex mirror.
Once cleaned, you say "O, that's the TV I was blown away by" WAY LESS screen grain
