Yes and no

What they will do is take a look at the failure rate of the DMD chips. If the failure rate is below a particular threshold, they will consider the chips a good batch.
Many LCD TVs die by getting a vertical or horizontal line or lines through the display. This is actually a defect, but if the defect rate is low and the TV has outlasted its warranty, they will consider that a normal failure.
Now, if one particular chip gets way above normal failure rates, then they know there's a problem with this chip. Those are the ones they will consider recalling or replacing.
I agree with you. Lots of DMD chips last loads longer than yours has. In fact, the vast majority do. This is why, personally, I've never liked the technology myself. Having something that can be on as long as a TV depend on a mechanical system for use is just stupid IMO. Electronics, plasma tubes and ccfl backlights are bad enough without adding in switching micro mirrors and colour wheels. On top of this issue, DLP also requires a very bright backlight (usually halogen) that also must be replaced every few years. Personally, I don't think DLP would ever be a tech I would pick unless it would be under fairly light use. In fact, if I do decide to go with a projector in the future, I think I'll get an LCD projector instead of DLP that must rely on a mechanical colour wheel, mechanical micro mirrors AND a halogen backlight. At least LCD eliminates two of those.
All this goes back again to the manufacturers warranties. As I mentioned, one year is nothing. Why can I get a three or (in some cases) four year warranty on an LCD monitor, but only one year on a TV that costs ten times as much? One thing you can feel good about, at least the part is available for your repair. Many companies (especially no-name companies) have no parts or service facilities. If I was in your shoes, I would try and see if I could get the DMD chip and replace it myself. There must be instructions on the 'net somewhere. Projectors require the optical black to be removed so the DMD chip can be replaced, but it sounds a lot harder than it is. TVs offer more room to work in, so it may not be as big a problem as projectors can be.
If you have a buddy who's into electronics/computers, and a case of beer with a pizza or two, you may be able to get it done relatively inexpensively.
