I just ran across one from '07 from Trigger 445, at this link:http://www.avsforum.com/avs-vb/showt...33#post9401033

"I have owned a Pro-510HD for about 5.5 years. After about 5 years, I had the "blue flash" and I fixed it myself, using instructions from this website--otherwise I may have simply gotten rid of the set. Well, I have always been impressed with the HD picture, and thought the SD picture was OK, until yesterday. I had calibrated it myself fairly well with the Avia disk, and had surface cleaned my optics once. However, now, all I can say is "wow, I never knew what I was missing"--I am amazed. Why? Well, yesterday, Mr Bob came and calibrated the set, cleaned the optics, and did an overscan reduction on my TV.
The basic cleaning of the optics is included in his basic calibration package (wiping off the top of the lenses and mirrors)(I had done this once before myself about 1 year ago, and it made a nice difference then, but was filthy again), but I also opted for the deep cleaning (removing the lens and cleaning the bottom of it and the convex below the lens)(wow, it was really dirty). I think this made the most "bang for the buck" difference, as the colors are now much more vibrant and alive than ever! If you have only a limited amount of money, at least contact him and at least have him "consult" with you on doing it yourself, or if you can, fly him and and have him do it--you'll be amazed.
The next best thing in my opinion was the calibration itself, which included mechanical focus of the lenses. My red and green were off a bit, and the blue was way off. Using his cantelever technique, he adjusted the red and green lenses to a sharp focus, and got the blue where it needed to be. Once the lenses were focused, he adjusted the convergence and at the same time took in the overscan reduction (overscan reduction was for additional price). With the overscan reduction, I have about 2 more inches worth of picture on the top and sides, and no longer is the scrolling box scores and headline news ticker cut off--it is like zooming out on the picture that is already there, effectively giving you more "pixels" on your fixed screen size. The overscan reduction took quite some time for him to align everything along the perimeter, as it takes in all the errors that are inherent at the perimeter in the design (which is why they overscan the picture to begin with, so you don't see the errors). Finally, he adjusted the greyscale, getting it much more of a true gray and the color/brightness/contrast/sharpness. The basic calibration (everything in this paragraph, except the overscan reduction) was the "second most bang for the buck" in my opinion, and the overscan reduction is a nicety, but certainly not required if you are trying to save a buck.
He was at my house for about 7 hours, and the picture I have right now on HD is absolutely amazing--far better than before (and I thought it was great to begin with)--breathtaking and truly vibrant, and the standard def picture is now great too. Even though he concentrated his effort on 1080i full screen as my primary "scanrate" for the overscan reduction/geometry adjustment/color alignment, the optics cleaning and the focus are both universal in their "help" to the other scanrates (480I/P). I now see why everyone says the CRT is the best out there--I thought they were all crazy until I had it ISF calibrated professionally--Thanks Mr Bob!"
Here was my reply:
"One of the side benefits Trigger got was that his grayscales on 480i and p got done in the process of doing the HD, even tho he didn't pay for any work on 480. Pioneer HDreadys are built on a "layered" grayscale and colorations system, where STD - S-video - is the basis, and affects all other modes - like the 1080i, 480p and component vs. S. The grayscale for STD is done first because it sets all the others in the process, then I did the HD as well, which is built on top of the STD settings.
The grayscale and color/tint for HD also apply to 480p, so he got those as perks. We didn't do the geometry/convergence on 480, but he can correct that at will in his user advanced grid, at least on red and blue.
After I was done I said, "Let's slide these viewing chairs up a bit." I believe they were at 8' and went to 6', but I'll let him correct me on that if need be. When we did, he sat back and said, "It's remarkable, the picture looks just as good up here." What's that, a 25% increase in viewed picture size? I don't know if he'll keep it that way, as the room ergonomics may not allow for it, but he at least knows he CAN if he wishes!
It was quite a fun job, and the meal his wife served all of us was just absolutely mouth watering, please convey that to her for me, Trigger.
And thanks for the nod! If between us we can save just a few more Pioneer HDreadys owned by people who are at present still on the fence about whether to keep or trash their sets, your words will have been more powerful than you know."
