1080p DLP Television
Published on August 20, 2006 By Draginol In Televisions

My ancient 35 inch standard TV finally gave up the ghost and it was time to go out and find a new TV.  Over the past several years, I've been keeping up with how HDTV has been progressing.

Presently, there's 3 technologies used to create HDTVs worth mentioning:

Plasma screens. DLP. And LCD.

Plasmas generally look the best when fairly large but are also very expensive.  LCDs tend to look the best when smaller but lose out at higher resolutions due to being a fixed resolution (especially if you're considering 1080p).  DLPs start to shine at higher resolutions but older ones tended to give a rainbow effect and have non-optimal contrast.

My living room is fairly large. As a result, I decided to go wtih the largest HDTV I could afford and that was a 71 inch one.  The new Samsung HL-S7178W was the one I decided to go with.

I chose it because of the size, its gaming features, it was a true 1080p (i.e. its inputs accept 1080p inputs) and it could handle 1080i and even standard definition and look fantastic.  It even has a game mode for people who have an XBOX 360 or whatever who want to get the best gaming experience.

The performance has been phenomenal.  I couldn't be happier with the TV.  The newer projectors eliminate for essentially everyone any sort of side effects of having a color wheel (though LED based lights are coming out next year but I doubt they'll show any noticealbe improvement).  Having looked at HDTVs for a few years now, it's amazing how far they've come in just the past 2 years. The quality of the picture is just much better.

Moreover, the TV's have gotten a lot smarter about their displays. Gone are the artifiacts one used to see and other noise elements that people with large screen HDTVs had to deal with. The newer sets such as this eliminate noise on the fly.  This really comes in handy when dealing with standard TV where the images look pretty good.

The feature I didn't know about but have found very useful is the USB connector on the side.  Just plug in your USB key and it'll play music and photos right on screen.  This is a very nice surprise because I can show slides of our new daughter at 1080p which look fantastic and conveniently play music through our surround sound home theater system in the room.

If I have any criticism of the set it is only that I wish it had more outputs on the back. I realize that my receiver should do more work but more outputs is always nice.  My other minor complaint is that it would be nice if more inputs were accessible. It does have some inputs on the side but an HDMI connector that was easily accessible fron the side would have been nice.

Overall, I would give the set a 9 out of 10. I really couldn't be more happy with it. It's obviously a huge step up from the ancient 35 inch TV we had.

We bought a new TV a few months ago, and we actually ended up buying a smaller TV than what we had so that we could afford to get an HDTV for my husband's 360.  (There also had to be some certain kind of jacks that I don't remember, which the TV we bought has...and they are conveniently placed on the side).

Ours is also a Samsung (so is our DVD player). 

It's AMAZING how many factors you have to consider when buying something as seemingly straight-forward as a TV.

71" is...wow...hahaha...if I had a TV that big, I wouldn't bother ever going to the movies.

I've been looking for the last few years at tvs as well.

I ruled out Plasma at first because it was supposed to be an "interim" technology...filling the gap between the old ray tube tv and HDTV.  And because they often got burn spots on them. And the life span isn't as long as I'd like for the price.

But Plasma tvs worked out most of the kinks in this year's models, (not the life span though) and if they come down in price, heh, they're a good bet.

LCD screens are nice...but the blacks aren't as black...and if you change directions by more than about 40 degrees left or right of center, the whole thing looks gray, dark and shadowy.  Plus, up until about a year or so ago they didn't come too large.

When I looked into DLP I ruled it out because "You can watch your DLP television about 70° to 75° in either direction from the center of the screen along what would be the horizontal or y-axis. This is not true of the vertical viewing axis. DLPs need to be positioned at eye level--any higher or lower makes for an awfully dim viewing experience. This is one area where flat-panel technology takes the prize for viewing flexibility."

So until they find a way to fix this attribute we won't buy one because I want one to go above my fireplace.  heh.  And that is much higher than eye level.

What really makes DLP rock is the fact they last so long and when they get dim, you literally just change a lite bulb to get brand new picture quality again.  If they could somehow work those mirrors to show the same quality picture at all levels.....well I'd OWN one. heh.  Texas Instruments has a good thing and they know it! 

 Thanks for the review.  I am printing it and storing it with my file on tvs (which is getting bigger and bigger and will soon be as big as my tv!)

AHA!  An ulterior motive! .

But what is the DLP technology.  I have not heard of it before, but then I have enough CRTs now that I am not really in the market.

DLP technology

Basically rear projection technology.....but with the use of mirrors made by Texas Instruments.

Check out my link above.

Check out my link above.

I did,  But got tired of the sales job.  Maybe I should have looked further.  But thanks for the thumbnail.

That is a great T.V. My neighbors got one this past Friday night. It is about the same size and I don't remember the brand, but it was wow. It was like looking into a tunnel. The picture went so deep. I want one now. I hate to admit it on this one, but I want to keep up with the Jones's because I can't keep up with the Wardell's, yet.

Thanks for the reviews.

Drooooooool.

So, is this seasons Superbowl party at Draginol's house?

I had a Samsung DLP and returned it because it had jagged edges and rainbow effects. My neighbor just got a huge LCD, and it looks unbelievable, but costs a pretty fortune to buy.

I hope you bought it at Costco.. Costco has a lifetime cash refund policy on all products. Considering these TVs last only 3-4 years on average, it makes sense to buy it where you can take it back for any reason, at any time, no questions asked. Its a NO BS policy, I returned a 3 year old DVD player to Costco last week in fact.

There are two models I really like at Costco for DLP fans (Head over to Costco.com to find em)

Mitsubishi 62" DLP for $3100

Mitsubishi 73" for $5400

Again, with a LIFETIME refund/return policy, it really is the only place anything should be purchased..

DLP's last more than 3 or 4 years. The bulb would likely need to be changed but otherwise. Heck, I have digital DLP projectors that are older than that and they've been through the ringer.
on Aug 21, 2006
I'd go with the Mitsubishis because they have edge smooth technology that Samsung lacks, and the jaggies/fuzzy edges were my major complaints with the Samsungs. Not to mention the Mitsu has a 160GB DVR built in, among other very very cool things. Either way, Costco is the way to go, because you can simply return it in a few years for newer technology.

With that being said, my next one will be an LCD, much better picture for the size I need. (40inch range)

3-4 years is the industry average lifespan for TV's according to the trade publications. I am sure some last a lot longer, some last less. Personally, most of my TV's have lasted 5 years+ except for RCA's which usually died after 1 year. Hehe

Hum, what are you reading specifically because nothing I read has that short of a life span.

And rear projection lasts the longest. That is why there are still so many of those 500 pound 1990's models out there.

If you have a big space and plan on buying LCD.....you have to sit almost right in front of it to get a good picture. Anymore than 40 degrees off center one way or another (on the horizontal) will greatly decrease your picture.

Even though you have to be eye level with rear projection to get the best pic....heh...when you get one 71 inches big...just about EVERYWHERE is eye level!

It is a sweet set Brad...hope your family enjoys it!

I just thought of Baby Einstein on 71 inches......buwhahahahahahah. Probably scare your daughter half to death.

Durability depends a lot on the TYPE of TV, and to some extent the brand. Factoring the "Average" failure rates according to AV Interactive (leading AV testing house)..

Durability goes something like this; (lowest to highest)

DLP (2-3 years, 15,000-20,000 MTBF)
Plasma (3-4 years, 20,000-25,000 MTBF)
CRT (4-6 Years, 25,000-30,000 MTBF)
LCD ( 6-10 years, 30,000-80,000 MTBF)

Although some manufacturers claim more, generally this is a good baseline to work from.. RCA CRTs when I sold them, averaged 1-2 years before they go "Poof". I was in the TV/electronic selling business for about 7 years, and still retain access to many trade journals. Regardless, nothing trumps buying from a store with a lifetime warranty - regardless of what you buy. Can't go wrong there!

Not to nit pick it to death but I think your numbers are outdated, unless you can give me a link verifying these. 

Here is just a sample of what I've got saved in some of my research from this year 2006.

"A DLP-based HDTV set should last indefinitely because the digital micromirror device behind it is very reliable. There is no maintenance or alignment required for DLP based sets as they age. The only consumer replaceable component is the DLP light source (lamp) which will last for 8,000 hours and costs around $250 to replace. The micro-mirrors used in DLP are not subject to degradation due to heat, humidity, vibration or "burn-in". "

http://www.plasmadepot.com/dlptv/dlptelevisionlifespan.html

"The lifespan of a plasma TV, contrary to rumor, is great. Also, the technology is ever advancing to produce better televisions that will last even longer. Most manufacturers will give an approximate lifespan of 60,000 hours for their plasma televisions. That's 20 to 25 years of normal viewing before the screen begins to noticeably dim."

http://ezinearticles.com/?Plasma-TV-Lifespan&id=138339

"Flat-panel LCD screen displays have a lifespan approaching 60,000 hours.   The most important thing to consider when it comes to the lifespan of your LCD TV is the actual lifespan of the light source in your LCD. LCD TVs last as long as their lightsources do. So, the lightsource in your LCD monitor is the critical component of your LCD display unit."

"Sharp is currently the only manufacturer that makes LCD displays whose lamps can be changed out. This is definitely something to consider, given that LCD monitors dim as their lightsources do, so being able to replace its lamp will restore your picture to "like new" levels."

Your numbers seem to correlate well with what I am saying, thanks for the links. (except they leave out some important things)

The MTBF for DLP's factors in Lamp Death, in technical terms it does not matter how or why a product fails regarding the MTBF (for example Lamp Death is considered unit death the same as an internal capacitor popping, MTBF is regardless of reason, a failure is a failure). Furthermore, $250-350 (which is average) for lamp replacement is a substantial portion of the total cost of the unit assuming you can do it yourself (if you can't add another $100-200) - thats a minimum. We're talking 10-40% of the total unit cost which is about average for repair of a typical CRT unit, and considering how they drop in price, at the MTBF of 15,000hours, that might be 75% of the cost of the unit by the time it fails.

Secondly, I should point out that manufacturers rate plasma MTBF at 50% brightness. *NOBODY* runs their plasmas at 50% brightness, if you do, they look poor, have lousy contrast, and are barely visible during the day. This is a misleading practice you can investigate yourself. Real MTBF on plasmas are 50% of manufacturers claims.

Finally, as for LCD's I don't see what you are desputing? I said 30K-80K, that article says 60K, thats about right in the ballpark, right? Remember, I quoted averages THROUGHOUT manufacturer lines from a company that evaluates MTBF's on over 25 manufacturers. So 60K MTBF is pretty mid-line from what I posted, about what you could expect from a nice Sharp LCD.
