Thanks for the quick reply BobF! Your posts have inspired me to venture into the bowels of my TV. I took some pictures during disassembly that I plan on sharing when I am done.
As much I would love a new 52-inch LCD, my Sony HS500 (which is essentially an XBR400 minus the HD detailer) has an incredible picture that I have not seen duplicated on any of the newer LCDs or plasmas.
After work tonight, I took the D-board and the two new MCZ3001DB chips to a local tv and electronics repair shop:
135 Main St
North Reading, MA 01864
He replaced both IC8002 and IC6501 chips. It took him about 15 minutes total, and he charged me $20 for the labor. The technician said that he has seen a number of these come in for repair for the same problem. The majority of the time it is IC8002 causing the problem.
I came home from work and re-installed the D-board. Surprisingly, it went back together fairly quickly - only took about 10 minutes. I plugged it in and it immediately turned on - just in time to watch the Red Sox and Tigers in HD!
Again...thanks BobF for inspiring me to do it myself.

Wow! That's great news! $20 is very reasonable to have a pro take care of the soldering.
I actually took my D-Board to a local repair technician before I attempted a repair myself. But he struggled with the desoldering task and then finally gave up on it. So not all technicians have the same level of ability.
It's interesting that your technician's experience was that, of the two MCZ3001D ICs on the D-Board, the IC8002 failed the majority of the time. That was my impression also from reading a number of online repair reports. So I replaced IC8002 first and then found that IC6501 was the problem on my XBR400.
And I'm glad I was able to help out.
