Samsung DLP w/ LED light engine

[PUMP]

Purchased my Samsung HLT-5087S with the led light engine in May 2008.
The leds are purported to last 20,000-hours. The red led on mine failed at 7,670-hours. Thanks to members in the AV Science forum (avsforum.com ) I was able to get parts and fix it myself at cost of $111.00. Turns out that samsung has to drive the red led at nearly full power most of the time in order to get required optical effect. This shortens the life of the red led. If any Talon member is considering purchasing of the Samsung DLP on the basis of extended operating hours for the leds, consider getting extended warranty.

Where did you get your data on the red drive? Doesn't sound correct to me.

My friend had a Samsung DLP purchased in I think 2006 go out and get bought back by Samsung due to a failure of the light tunnel I think. Some massive expensive part that as it fails, the picture starts disappearing from one side of the screen.

My set has been great though. Its an HL-6167W I think.

Samsung no longer makes a Dlp for over a year now.. I have a 67'' Samsung Dlp Led I bought 3 years ago no problems yet..

DLP is great, I still need more patents to get filed.;)

Seriously though DLP still has one of the best pictures, but the desire for people to save a few inches in their huge living rooms on depth has just about killed it for the TVs.
Very few mount a LCD or Plasma over 50 inches on the wall, and those that do put it over their fireplace, way out of the desired viewing angles, I don't understand the thought processes on these decisions.

Thats the way i sold back in 07 when Dlp was hot and paid like crazy. Now it seems with they was the pay us the dont care if the technology survives or not..

My father was just about to do that and I said what are you thinking? the line of sight is much lower than that and you will get tired of looking UP at it all the time..

Info came from the AV Science forum and much of it was supposition. So maybe it ain't accurate. I saw 10 (or more) separate reports of red led failure with 4,000 to 13,000 hours. Most were beyond the 1-year warranty. I did not see any reports of failure in green or blue led. One guy went so far as to check with the manufacturer of the leds and reported that the manufacturer claimed 20,000-hour life under normal power but that it was possible to over drive them. Design of the heat sinks for the led component is also a good indicator. The heat sink for the red is signifigantly larger (by a factor around 2x) than either the blue one for blue or green. I don't know diddly about power required to drive the leds, but I do know heat exchangers.
I contacted Samsung's customer service to complain and the rep that I talked to just blew me off. I can understand premature failure, but 1/3 of expected life is beyond what one would expect for infant mortality.
I still love the picture quality and would probably still go with the DLP, just reporting my experience.

I did a little digging and probably found what you found. It seems the red led can just be plugged in once you buy it. I assume that is what you did. Some other thoughts is it gets really dusty in there and the leds overheat. Did you find a lot of dust in yours? I may need to open the back of mine and clean it out.

PM me with your email address and I'll send you a pdf copy of the service manual that will save you $10. It is slightly more complicated than plug and play, but relatively straightforward. You have to use thermal compound (Artic Silver from Radio Shack, to enhance heat transfer) between the led chip and the heat sink. Took me about 2-hours to do it (and half of that was reading the manual and figuring out how some of the terminal connectors released, my eyes aint as good as they once were).

Old guys designed and built the first DLP TVs, and now it is proven old guys can fix them.:tu:
They may drive things harder than I know and the thermal grease is important.

I'm keeping my 61" DLP...thank you very much. :cool:

[Silver_2000]

Im happy with my lowly 50 inch LED DLP

Its now 3 or 4 years old

I will at some point get rid of the 36 tube in the bedroom and get a 40-50 plasma for there
It will also help keep the room warm :evil

What about performance and efficiency

A close friend of mine has a Samsung 67" & he has had something go wrong every year since he bought it. Less than a year after he bought it the color wheel went out, has been replaced 2ce that I know of & a couple of months ago the TV failed with what is believed to be a video processor. Likely he will not be spending more money on it going forward... I must say the picture was very impressive until the first time it was repaired, has not been correct since.
