I was just at one of my competitors shops today and talking to one of his guys about DLP rear projos. This particular salesperson had sold 3 samsung units prior to the big blackout last month (and subsequent rolling blackouts). What happened to 2 out of the 3 that he sold? (the 3rd wasn't watching at the time) They were both destroyed by the sudden loss of power. Apparently the DLP runs extremely hot, which is no problem since it it cooled by a fan, but the fan is supposed to run for up to 30 mins after the set is turned off. Apparently if the power goes off it can wreak havoc since the set doesn't have a chance to cool down. He was on the phone with a top samsung service guy who was very concerned that this could become a major problem and apparently nobody there had been able to figure out what this tech at a repairshop in town came up with. So whatever comes of this, for any DLP owners I may suggest investing in an uninterrupted power supply unit so that you can turn your set off safely if the power does happen to go out.
