Another question for my favorite research dept ;) (ln52a650)

Mar 25, 2009 10:43AM PDT

I again have the ln52a650... love it still... just got it yesteday. Ok, I can't find anywhere it saying specifically what the bulb/lamp life is. Does anyone know these specs? Given a good 18 hours of operation everyday, how long do you think it would take for the bulb to dim? And how much would a replacement be? I know some of the sxrd's came w/ a replacement bulb, and I know the new led's aren't supposed to need replacing. I'm thinking I heard only to expect a couple of years of good lamp life before needing to replace the bulb. Is this still the case?

mtelsey1,

Such a compliment, how could I refuse? Wink

The lamp life on your unit is 60,000 hours to half-brightness.

So figure 18 hours a day, every day, your CCFL panel should last for 9.13242 years before reaching its half-brightness point.

Some of the other technologies from ours and other manufacturers were projection style, and those lamps lasted usually around 6,000 hours which would last .91 years at 18 hours per day. For that reason, a second bulb was packaged to increased the value of a lamp that they expected a user to replace within a few years, of course, not figuring on 18 hours a day as the norm.

The replacement cost for a lamp housing depends largely on which model, and when it's done. I wouldn't even be able to give you a rough estimate, but maybe you could find something on samsungparts.com for the cost of the part, not including installation.

Does that help?

Thanks so much! I don't have much experience w/ lcd's aside from computer monitors, and you don't really look for as much in those. Wow, 9 years to half-life that is great news. Yes, we watch a lot of tv.. and I plan to start curving some habits w/ the new tv. My old tv was an hdtv projection, and it has burn in terribly from watching a lot of tv in 4:3 format. I hate to stretch the picture on non-hd programming. Consequently, this is one of the habits I have curved w/ the new tv so I don't get the same burn-in problem. Thanks again!!! I'll be back again when my next question arises.
