I have a large DLP Hi Def Samsung. Lamp in it lasts from 4000-9000 hours. My lamp lasts already for 17000 hours and is still working because I run it at lowest brightness all the time. But Samsung company made sure that if that happens TV automatically shuts down my WORKING lamp, and wants me to buy a new one. This kind of product was unthinkable 30-40 years ago, This is exactly why we have and will continue to have all kinds of economic problems. We have completely strayed from quality, from endurance, from down right honesty. I am disappointing with what became normal business practice. This won't end well.
