A TV is never your last resort.
He mentioned that his wife had cleaned the screen with windex. Would this lead to smudging of the AR coating? If so, would it be very obvious to the eye when the set is off/on?
There are two worst case possibilities. With enough effort, his wife may have removed all the coating. Or she might have removed only some of it. I'm not sure which would be worse. Take a flash light and check the screen for small cracks by shinning the light on the screen from a sharp angle. You want to do that with the set off. Also check out the coating to see how it looks. If she was very careful, didn't rub hard, and used a camera grade micro fiber cloth then there might not be any damage that you can detect.
The second worst case is that she got some of the windex into the electronics by bathing the screen in it. I have no idea what windex would do to electronic parts if the set didn't short out.
It doesn't sound like the owner checked the manual before letting his wife scrub the screen.
What other factors/issues to look for when buying a used Kuro, besides dead/stuck pixels? Are they easy to spot: should I bring a thumbdrive with Evangelo2's break-in slides to check for uniformity?
That's a good way to check a screen. Remember that a stuck pixel shoiuldn't be a problem if you can't see it when viewing normal material at your normal viewing distance.
Also, it has been sitting in a basement wrapped in furniture plastic for a few months.
What kind of basement. I would worry if it's not living space where temperature and humidity are somewhat controlled. I don't recall reading why the owner move the Kuro to his basement, and stopped using it. That might concern me depending on my impression of the owner, his home, and his story.
If he has a bill of sale, that's in his name, from a known dealer, then you can estimate the maximum time that the set could have been used. Viewing hours would be the least of my concerns. If he doesn't have a bill of sale as I described then I doubt that I would by his set. "The dog eat it." is not an expectable excuse from my point of view.
After checking the screen with the set on, I would watch a variety of material for at least thirty minutes. Will you have a Blu-ray player to use for testing?
I think there are extended warranties that can be bought if it's done before the warranty expires. I don't know if you can do that if you're not the original owner.
