I'm a newbie obsessing about the 67a750. I have a samsung HLR5667W currently and think it's a good TV. I am seeing some comments regarding LED not being as good as a lamp, and a potential problem with the screen sagging? Not exactly sure what this means.

Can someone comment on LED vs lamp on this unit, and has the sag issue been addressed?

While I can't comment on the LED vs. Lamp issue, I can comment on the 'screen sag'. There was an issue with the 2007 Lamp based sets, and to a lesser degree the LED sets (I believe), where they would exhibit horizontal bowing. Imagine horizontal lines not being completely straight, but forming a smile at the edges. It is caused by less than rigid screens, and compounded by the case design on these models. In particular the Lamp based sets, HL-TXX76s.

They developed these "Ultra Slim" cases, which were 6-8" thinner depth wise compared to the previous versions. To achieve that, they changed the optic system and added another mirror in the top of the case, which would magnify any geometry problems. The case is also very, VERY flimsy. If the case was sturdy, I imagine the bowing problem would be much less severe, as it would support the screen. So to sumarize, we've got an additional mirror, a flimsy case, which is pushing down on a flimsy screen, causing it to bulge out causing the smiley face effect.

I've had the HL-T5076s since June '07, and above is what I understand is the problem. I haven't complained to Samsung yet, because I know they don't have a fix as this is an inherent design issue with the Ultra Slim cases. Some have gotten lucky after going through multiple replacements and gotten one with little to no bowing, but who wants to exchange their TV 4 times. The good news is that the '08 models no longer utilize this design, and have gone back to the previous slightly deeper cases. While we won't know for sure until the sets start trickling into stores and the first AVS'ers get them in house, it's a fairly good bet the 'screen sag' won't be an issue this year. If that's so, I'll be calling Samsung to complain until they give me a non bowing set. Hopefully this is helpful in explaining the geometry problems of last years televisions. Maybe someone else can discuss LED vs. Lamp.

BTW, aside from bowing, the PQ is outstanding!

LED vs Lamps

Pretty simply. Lamps are a mature technology. They are made to be very bright with an excellent white balance. They cost $10 to make and are sold for $300, so you can see why the manufactures don't want to leave them behind.
LED is a relatively new technology. It has not been that many years since researchers have been able to develop LEDs that emit light at the correct frequencies. Now they are working on making them brighter. In the 2007 model year the LED models had to use a screen which had an extremely tight sweet-spot due to the considerably lower light output of the LED engine when compared to a lamp. This also had a side-effect of reducing the contrast ratio which in theory would be very good, but was degraded by using a screen that focused all the light straight forward. The 2008 models are being advertised as being 40-50% brighter. Does that mean a normal screen can be used and off-center viewing will improve as will contrast? I don't know. They won't even announce if it has Darkchip4 or not and they have already arrived at warehouses!
Also, FYI - the LED engine is a Platlight and is made in New Jersey. Likewise, the DLP chip is Texas Instruments. Right now a Samsung LED DLP RPTV is the most American a TV as you can buy. It matters to me, your mileage may vary.

LED vs Lamp came down to PQ and viewing angles to me. The bulb can be a pain yes but for the same money I can get a warranty to cover a bulb or 2 for some extra green. This should be done anyway on a rear projection. Viewing angles on the LED sets were terrible and they did not seem to have the same "pop" especially in the ability to produce blacks.

Last years bulb sets were a disaster due to the cabinet as posted above. I am on my second set and that one is going back too. My kid runs in the room and the picture shakes due to that mirror being mounted on top.

Do LED's dim as badly over time as traditional lamps? I'm looking to replace this 4 or 5 year old work horse RPJ LCD, and while the bulb is somehow still going, it's probably at a fourth (or less) of its once peak output.

Are you saying that you have the 2008 series A650s & A750s in your delivery system? Could you comment on which store you work for? I'm very anxious to see these in person.

I don't know about all you other guys, but I am very happy to hear this news. It's great to know that although we haven't even had any info on the Series 7s that they are still looking to be ready for an April purchase date.

The only thing left for me to really stress about now is how long it will take the Sears here in Hilo, Hawaii to get one (HL61A750). I envy all of you greatly that are able to have so many choices available to you. Every single website I've been to will not ship TVs to Hawaii so that eliminates so many choices and possible deals. On top of it all, as Hilo is not the biggest of cities, Sears is the ONLY choice I have to buy my TVs. No Circuit City, Best Buy, Fry's, NOTHING! (Wal-Mart and Radio Shack are here but have absolute crap as far as TVs go). Anyway, hopefully they'll ship some over here before too long. I'm already going crazy, so keep posting news as that's the only thing I have to keep me alive!

Yeah, but at least you get to live in Hawaii, so you get no sympathy from me! We're supposed to get 2-4 more inches of snow here in Michigan tomorrow.

Still nothing on Samsung's site about the 750s. All the info should be available already, this is getting rediculous.

yankeeman & NismoZ -

Nothing confirmed, but there was this from Erock1 a page or so back:

"On a side note. I stopped into BB last night and chatted up the Magnolia manager about the 61A750. They show 1 at their wharehouse for delivery next week. I asked about specs, specifically what TI chp and said that would be the deal breaker. He called their sammy sales rep (on speaker phone) and put the question to him. The sammy rep's answer was, TI DC4 for what it's worth."

That is good info there. Hope the Samsung rep is right.

It looks like you might be the first one on this board to actually get one. There was someone else who ordered off Crutchfield but supposedly Crutchfield is not getting it until 3/31.
I'm sure you'll be getting a ton of questions once it arrives!

WooHoo! My comparative opinion may be of little relevance, however, as I'm replacing my 23 year old 20" Sony, so I'll be easily impressed.

Didn't someone earlier in the thread say tentative street sale date was 03/19 for the 61 and 03/23 for the 67?

If that is the case, we may actually have a 61 in OUR store.

I have been off for 3 days but I will definitely check tomorrow.

If it is there, it will be opened.

At least in Tulsa... well, they are one short. I'm enjoying March Madness from my living room with my new HL61A750! I got mine from the 71st and 169 store even though I live in Owasso and they have one too they didn't want to deal with me like the other store did.

This is my first HD TV so I'm impressed as expected but I don't think I can comment on the specs too much since this is so new to me

I'd provide any comments that I can if somebody provides me the proper details.

Is that the bulb 650 or LED 750?

It has to say something about contrast ratio somewhere?

They could have thrown an even more exaggerated number out there though with the same exact tech., so we need a measured ansi contrast ratio.
