Apparently, it's a widespread problem, because I've been through three used boards, which solved my problem completely, but caused different worse problems of their own, and all three exhibited different problems. In each case, putting my board back in returned me to my original problem. I know I'm ordering the right part, because Sony has published a document on the subject including part numbers for serial number ranges. More on my experience with this problem here
The only conclusion is that the three companies that shipped me parts are salvaging broken TVs, harvesting the parts, and selling them without testing them. At least shopjimmy.com and retechtv.com issued full refunds and prepaid return labels without any hassle. The other company lied to me repeatedly about the return label. The fourth company I ordered from didn't ship me anything. I had to get my credit card company involved in the last two.
I did call Sony and got a couple of heavily accented "agents", one of which rudely suggested, "Why don't you just buy a new TV so you won't have to worry about this?" That's real nice considering I spent $1700 on the TV and used it maybe a couple of hours a day for 4 years. Then she blew me off to "Herman's TV Repair", whose phone number matched encompassparts.com, a site I had blocked long ago from google search results due to its ridiculous pricing, which is even worse than Sony's, with a $180 refundable (yeah right) "rebuild fee" on top of the $413. That's another thing. Many of these parts stores go by multiple names, and their web sites conceal them. For example, "HDTV PartsStore" is really Tri-State Module, and don't get me started with the Asian shops in NYC. I've blocked a couple dozen of these scam sites in google search.
So, I'm looking for a new TV, and the sad thing is, all the manufacturers are the same. TVs have become cheap, disposable junk, made by companies who don't care, and class action lawsuits seem to be the only way to get any kind of remedy out of them.
Oh, and to the guy asking if a stuck pixel is acceptable in a new TV? Absolutely not. In a TV as expensive as the HX850, I'd demand near perfection in every area, such that I wouldn't be living with anything that's going to even mildly bug me.
