2007 Samsung LED Owner's Thread (HLT XX87/89S) - Page 188

I'm trying to decide between the HL-T and Sony's A3000. Has anyone confirmed that

(a) the frame rate on these sets is, in fact, 120 FULL frames per second, as opposed to 120 wobulated, half-frames per second, and, if so, that

(b) these sets do 24*5 = 120 judder-free frames per second, when displaying 24fps sources, in lieu of 3:2 pulldown?

The Sony's treatment of 24fps sources seems clear. I've searched this forum heavily on this issue, and am still not sure about these Sammies. Even the results of an empirical test, from someone who has an HL-T and understands what I'm asking, would be welcome.

Also: has anyone learned anything about the longevity of the DLP technology, in these Samsungs, compared to that of the SXRD technology in the Sonys? I've read that DLP longevity is good, but nobody seems to have a clue about SXRD longevity (I already know about the "green blobs").

are the light engines diff in the 89s versus the 87s?? What exactly did the tech swap out the last time?? And what parts is she replacing this time? I had a tech come out but only with 2 parts the light tunnel lon black block of plastic that house the LEDs and the mirror assembly....nothing on my set looks like a "cd-rom drive" its all stuff connected to each other....i'll take a pic next time the tech is out here to replace my optical stuff, he is awaiting a service guide as to whether or not he can install it in my home with no problems or if he needs to take it to the shop which i firmly do not want him to do. Does anyone know if the alignment screws on the mirror (light illumination assembly) are for tilt only? David Abrams you can chime in if you know the answer which i am sure u do...i have a 5687S by the way....

Got my replacement 5689s today. No rainbows so far. However I notice ALOT more screen door effect on this set. It also made an extremely loud humming noise when first turned on. Snow flakes are still there when xbox360 is set to 1080p over component.
Its almost like Samsung is trying to make me go with the A3000.
Will give it a week to officially make up my mind.

I'm pretty sure these sets are "emulated 120hz", whereas Sony is "true"? 120hz.. i think as someone put it, its all marketing words for the same thing.

However, does anyone own a 6187S and a Blu Ray player in 1080p24 mode and presses the tv info button and sees 1920x1080@24hz on the screen? Mine only says @60hz.. someone said with the ps3 it showed @24hz.. Not sure why the BluRay player would force the tv to say @60hz when I have it set that way..

On your question of longevity, I've heard 8000 hours on the SXRD's.. vs about 20,000 to as high as 200,000 for LED.

PS3 with setting turned on for 1080P/24fps connected via HDMI...hope this answers ur question actually i have a 5687S with firmware 1026...should be the same tho for 6187S with 1026...

Almost.. except yours is a PS3.. i'm using a BDP-S300 bluray player.. set to 24p.. for whatever reason it shows as @60hz.. Someone else with the same set and 1026 firmware and same BD player shows @60hz too.

Puzzled as to why.

perhaps the PS3 is a superior Blu-Ray player...i have no clue...how long have u had the player? Return it if u can and get a PS3 if at all possible, or if it means that much to u...all i can really say i guess...maybe David Abrams knows the answer? Maybe the player has a firmware update for it, the PS3 needed a firmware update to obtain the setting to turn on 24/fps

I have an HLT6189S with firmware 1011 and I get 1920x1080@24hz via Blu-Ray (PS3) without any issues. From what I've read here 24fps is not an issue with the HLTXX89 sets.

I doubt you can see any SDE on a 1080p DLP RPTV set that is wobulated, and at this time they are all wobulated.

Screen Door Effect is caused by seeing the space between pixels on the screen, and looks like the grid of lines you might see in an actual screen door.

Wobulated 1080p DLP sets have very small pixels, and because of wobulation they are slightly over lapped by their neighboring pixels.

You may be referring to something else. How far are you from the screen when you see what you are calling SDE?

u should take a pic of what u r experiencing....it would make it more clear

What is darkchip 4?

jim

Here's a weblink to the dark chip 4 annoucement. This link also makes reference to how it will be working with all technologies. In the article it makes reference on how the new chip and the LED technologies will have a contrast ratio beyond 100,000 to 1 (according to the article).

maybe a different thread should be started, let's stay on the topic of the Samsung HL-T XX87/89S sets people!!!!!! Dark chip 4 has nothing to do with this years LED sets....just stay on topic please

Perhaps I'm not using the right term. What I'm refering to is the heavy amount of pixelation that, for example, when looking at water on DiscoveryHD makes it look like blocks even though there's no motion on the screen. Usually this effect has to do with refresh rate/compression? I'm sitting 10' from the screen.

I also just had the pleasure of seeing my first halo prism reflection while switching between the xbox dashboard and the game. Nice big purple blob on the bottom of the screen along with 2 smaller purple circles in the center.
This is my 2nd set and obviously it's going back, could someone explain to me why this is Samsung's so called flagship model? Where's the quality control?

Wopino I would agree that It's not directly related to this link. MY apologies for getting things off track. But I have say that HDMI, Component, and Blu ray technologies about the 87/89 tv's (directly). But when I made my comment it is only meant as information to current owners and potential new owners (like myself) to give them information as to what's going on with the LED technologies and how it's evolving. Unlike others who only want to bash and demean the Samsung LED technology instead of understanding what it gives us and the potentials for this technology for the consumers. Some people like to bash and speak highly of other products that are allegedly better.

jim

No one here is "demeaning" the LED technology or its potential. However it's fairly evident, and some if not most would agree, that Samsung rushed these units to the market without thoroughly testing them. If you read through this thread you will see that numorous people are experiencing a handful of similar issues.
I really hope Samsung figures it out as I would love to actually own one these displays as problem free.
I will continue to enjoy the 32" Sammy lcd in the spare bedroom but I dont want to have to explain to my friends who come over to watch NFL Ticket what that purple blob on Manning's jersey is or why there's flashes of rainbow on Lovie Smith's head. If I bought this set used from a college kid on craig's list then maybe, but I expect more from my pricy electronics.

i guess there's still some question with our set and 24hz sources. i have a 5087s and my PS3 sends 24hz and the sammy receives it just fine. i of course upgraded to the latest firmware so nicely shared by the members on this forum. all you have to do is search this thread. its scattered around. the firmware upgrade is simple and straightforward given you have a USB key laying around.

Right.


What you are describing sounds like a problem with your digital signal coming into the TV. You need to tell us exactly what source (program and input device) that you are watching and how it is connected to your set. There can be a lot of causes for what you are describing.

Here is a link to Wikipedia's definition of Pixelation.


If the input signal has drop outs or extreme compression you might see what you have described. It's caused when the TV isn't getting enough data to complete the whole image. It's most easy to see when a signal is compressed and the image involves fast action. There just isn't enough data to keep up with the action.


If you saw this while the image was switching and not while you were watching actual programming then I'm not sure what the problem is. Are you saying that you see the purple blob on any black screen?

All brands and technologies have problems. It's hard to tell what problems you are having, and what is causing them without more information.

As a rule of thumb, it's a good idea to pick the company and model with the set of problems and price that you are most comfortable living with.

I think Samsung is having more problems this year because they have gone into two new technology areas. One is LED for a light source which might be related to the purple blob you have seen.

The other problem seems to me to be related to Samsung's desire to have cases that are as thin as possible.

I think of quality control as an issue that comes up when a company takes working parts and puts them together in such a way that they don't work according to specification. Samsung may be guilty of that too, but they also have some engineering problems to deal with.

You may find a TV from some other company that works better for you.

Good luck.

Now you need to find out what causes a small percentage of people to see rainbows on any projection device that uses a single chip design compined with some methode for flashing red, green, and blue onto the screen at very high speeds.

The rainbows, for those who can see them are caused by a bright spot (white mostly) moving rapidly over a dark background. Some folks see the red, blue and green seperating instead of their combined result which is white.

I don't think Lovie Smith's head can produce the effect that folks here refer to as rainbows. There's not enough motion, and it's not bright enough.

DLP is the most common single chip technology for RPTV, and for front projection home theaters. That's why you hear about rainbows and DLP so much. Philips did a LCoS set using one chip a few years ago, and produced some amazing rainbows.

Any three chip technology, LCoS(SXRD), LCD, or DLP, will not cause anyone to see rainbows because red, blue, and green arrive at the screen at the same time.

Here is a simulation of what rainbows are supposed to look like. I can't varify that because I've never seen one.

So noone here can confirm that on a BluRay player other than the PS3 and on the 6187 they are getting 24hz?

When I watch a blu-ray movie thru my Ps3 the picture is bad and there's a white flinker and the background. Someone from Samsung already came out and replace a board and I'm still having this problem. So, I exchanged my Ps3 thinking that was the problem but nothing changed. But when I change my ps3 setting to 1080i the picture is alittle better and the flinkering goes away. I was just wondering for anyone heard of this problem before.

I can confirm that with the PS3, I can get the tv to display 1920x1080@24hz. I have the 6187S.

Another question I had is, I have my laptop plugged in via HDMI to the 5687S, and I'm noticing the edges of the taskbar and top windows are cut short. I can't see the full time, my start button is slightly cut and I can't see the top very good. Is this a setting on the tv? I tried every setting on my laptop and still nothing.

It sounds like you are watching a TV in the store. They all looked bad until I got it home and used quality sources. This thing looks better than any TV. The pixel problem with flowing water is not a problem. Try a regular antenna to get OTA HDTV from your local stations and see what your TV is capable

I figured i'd quote myself because I fixed it real fast on my 5687S.

When you have your laptop setup via HDMI, you have to go to:

Menu, Input, Edit Input.

This allows you to change the name of HDMI3 input to PC. When you do that, it automatically allows the "Home Theater PC" option to be selected in the Picture options menu. Then this properly displays the entire desktop in clean edges on the entire set.

The only bad thing is I can't get audio in from HDMI to the TV for whatever reason...

Is the water sparkling even though there is no motion of objects or the camera? This sounds very much like mpeg compression artifacting. Sparkling water is very dynamic and one of the biggest compression bit hogs. Yell at Discovery and/or your cable provider for being cheap and trying to cram too many channels down a limited pipe to save a buck.

No the water wasn't sparkling. What I was saying a few posts back is this is my second 5689s and the first one showed hardly any pixelation/artifact/compression...however it did have a nasty RBE hence the exchange. I'm well aware of signal issues thats is why I had the D* installer run all new cabling when I moved into my house. Also using Monster Clean Power Stage 2.
So I believe my gripe is more with Samsung than anything. I went from rainbows and snow flakes to halo prism, snow flakes, and artifact.

i could not agree with you more!!! I too am awaiting the day that i can turn on my television and see no halo-prism the whole time i am watching no matter what i am watching....i am really getting tired of seeing it lol...hopefully Samsung fixes their replacement parts to solve this problem that seems like the majority of sets have this problem...

Yes I did notice the image last night during programming as well. Purple hue at the bottom of the screen on TNTHD.

I completely agree with you that all technology has it's faults and it's a toss up of which faults you want to deal with from which OEM. What gets to me is ok you rushed out a product, it has problems..at least acknowledge them. The 5-6 times I called Samsung support about these issues I received the standard "Really? I never heard of RBE or halo prism on these sets, you're the first one to notice this"

Perhaps I'll come back to LED in a couple years when they get it right but for now I'm shopping for a replacement.

Excellent . I'll leave well enough alone then.

Thanks for the response.
