The Downside of HDTV
Since I know you've all been tempted to upgrade (yeah right), I'll mention that the bulb went out in our Samsung DLP TV last night. While this was something we knew would happen, there was no warning, and the behavior of the unit after the failure was somewhat more bizarre than the "three flashing lights" indicated in the manual. And of course the most shocking part was learning we had already had the TV over two years! With a 2000-hour bulb life expectation (Samsung says 5000-8000, but no one is achieving this, probably because you'd have to be watching in pitch dark all the time), that works out to about 2.6 hours of TV per day. Frankly, I'm sure we exceeded that, and that's not even counting all the times we've accidentally left it on overnight and intentionally left it on for 16 hours for weekends, parties or whatever.
Also, according to this knowledgebase article, we probably cut the bulb life in half by running "dynamic mode" all the time and unknowingly overdriving the bulb by 20%.
Note: If using the dynamic setting in the picture mode of the menu, this can affect the life of the bulb. When using the dynamic setting the 100 watt bulb operates at 120 watts causing the picture to look brighter. This will shorten the life of the bulb by about 2,000 hours.Perhaps if we had ever gotten around to watching Blade Runner on the thing--and really, what's the point of having an HDTV if you're not watching Blade Runner? Doh!--we'd have remembered that the ultra-high pressure lamp that burns twice as bright burns half as long!
We'll have the new bulb tomorrow, at the cost of buying only a "normal" TV all over again, but this has meant a full tear-down of the entertainment center (once again) and cracking open the case on the TV itself. I'm not complaining, just caveat emptor, as always.
