Samsung's new TXN series thoughts? - Page 2  

post #31 of 280
on vacation and just checked back. I did get the TV and will play with it this weekend. One thing I noticed, I connected the HD cable box to the Component Video 1 of the Samsung TV. The non_HD channels put two bars on each side of the picture which I expect, however the side bars appear "curvy" (not striaght vertical lines where the black bar meets the image)..is this an articfact of trying to watch non_HD channels through the Component Video input? or should I be concerned about a defect. Looks great when viewing HD channels but I have to switch to standard S-video or cable to watch the non-HD channels.

I was looking at one of the new TXN 30" HDTV-ready widescreen Samsungs at bestbuy. It could be my imagination, but it seemed like the CRT grille was finer (more closely spaced) than Samsung's 32" 4:3 (also a new TXN model.)

Was I imagining things?
post #33 of 280
Z4NC you will have to enter the service menu and access the deflection menu to correct geometry. All tv's have imperfect geometry ouit of the box but Samsung is worst than most. It is not a defect. Purchase a setup dvd such as AVIA, record ALL of the original service menu settings then fix geometry using the setup test patterns. It is really quite simple.

I know the 30" TXN's have the superfine dot pitch crts for increased resolution. Not sure if the 4:3 sets have them. This may account for the difference in the crt grill.

I ordered the AVIA setup DVD today.

Just got DirecTv hooked up last night to my new 3075 and old 20" Panasonic.

As expected the picture is rather pixelised on the 3075. Up close it is really bad but from 8 feet away is acceptable. It also looks quite soft, and adjusting sharpness only leads to greater pixelisation. I am using the receiver my system came with and the S-video input. Composite video is a bit worse. I don't think I would be interested at this point in buying a receiver with component out.

DirecTV on my old 20" Panasonic is very good tho with composite video and the same receiver.

Now I know what all the moaning is about for Hi Def tv. I would love to watch all my satellite stations in hi def on the 3075 widescreen. Right now I think I will watch most of my tv on the old 4:3 analog Panasonic and save the 3075 for dvd. I guess I was spoiled with the dvd pic quality and am a tad disappointed with satellite on this digital set.

Only problem is my wife loves the TLC channel and will want to use the old Panasonic as well! Now I have to decide if I want to keep the 3075 or return it for a new analog 36" capable of vertical compression. Hmmmmmm..........love the dvd pic on the 3075 but would also enjoy the better satellite pic quality on an analog set. Do I dare entertain the thought of getting last years Akai 30" widescreen analog that only accepts 480i for $500 from a Sam's Club store (2.5 hours drive away)??!!! Anyone own the 30" Akai?

WidescreenDream:

Interesting post, I'm currently considering getting one of the new 3098s or a 32" 4:3 for a new TV to last for a number of years. I am also coming from an old 20" (mine is Magnavox). I have DishNetwork, so I would also be doing satelite. Does it really look better on the old 20" than on the TXN? That kind of scares me.
post #37 of 280
Cable or satellite will always look better on an analog set than on a digital tv. Digital tv's have greater resolution and therefore show any picture imperfections quite noticeably. Analog tv's are alot more forgiving.

That is why buying a tv is such a hard decision in this interim between standard analog broadcasting and full blown hi def tv. Supposedly in 2007 all broadcasters must use a hi def signal as well as analog. But this is 4 years from now and even then this mandate is not set in stone.

I watch about 50% tv and 50% dvd so the decision is really difficult for me. I am thinking the best compromise might be an analog widescreen so I am trying to get my hands on the Akai. Cable or satellite will be very nice and dvd will at least still be widescreen but without a progressive scan picture and 3:2 pulldown. At $500 the price is also very good. This might be the best route to go for now and upgrade if hi def is broadcast for all channels in the future.

O got the Avia test pattern I'm at the deflection menu...but can;t change the values using the + and - keys...how do you change values using the remote?
post #39 of 280
I don't have the remote in front of me but you should be able to change these values like any of the other settings. Once you are in the deflection menu you must first select the variable you wish to change and it will take you to a screen with just that variable. Now you should be able to change it with the remote.

You should also correct overscan with the AVIA dvd as well. Every tv is different but overscan was set too high at the factory on mine. 5% on both sides is the right setting.

In the service menu you can also adjust geometry for certain inputs - 480i, 480p and 1080i.

Just make sure to write down all the original values before you do anything. Then you can experiment with each setting to get geometry just the way you want.
post #40 of 280
can not adjust defelction values in 480p mode..has to be 480i..WSDream thanks for all youyr advice after doing the AVIA adjustments and correcting the geometry this thing looks awesome!
post #41 of 280
Glad you like your set. The TXN series is an excellent monitor once tweaked and without doubt the best value in hdtv today.

I will be going next weekend to look at the analog Akai 30". If it looks good I will be returning the 3075 to Circuit City. I am not really interested in viewing hdtv and while the dvd pic quality is awesome on the 3075 I am thinking I won't mind compromising a bit on dvd for a much improved standard def cable pic. I will post an update and a review if I get my hands on the Akai.

Just noticed that bhphotovideo.com has the Samsung TXN3098WHF in stock for $1299.99. Are there any takers out there yet?

My TXN3075 does not have it and the store model was fine as well, so I am assuming the problem has been corrected since all TXN tv's suffered from this.
<snip>
Unfortunately, I have to disagree. I just triumphantly set up my brand-new TXN2771 and started watching it. I didn't notice it for the first hour or so, but then all of a sudden my eyes snapped to not one, but TWO "light vertical bands about 2 inches wide" running vertically down the screen. The actually move very slowly from right to left, making a complete traverse in maybe 30-40 minutes or so. They are far more visible under certain conditions than others, so I have no way to know how long they were present before I finally noticed them.

To be specific: They are actually bands of "darkness" superimposed on the picture. They are very obvious when the picture goes black momentarily between commercials, or any time the background is a uniform color. Colors go "dim" across the band. On the black screens, the bands show up a dark, clear black compared to the faintly noisy charcoal "black" of the rest of the display.

Unfortunately, they are VERY noticeable to me, and it's VERY distracting. Far worse than I should expect from a $700 television, IMHO.

The bands do not appear when using the component video feed from my DVD player. My only other connection at the moment (and so the one where the bands are visible) is a composite signal from my digital cable converter passed through my VCR and sent as a composite signal into the TV. Because of the size of the TV and the geometry of my entertainment center, it's a pain in the tuckus to get to the connectors, so I haven't swapped anything around to check out different source configs (i.e., dunno if S-video straight from cable box would fix problem, for instance).

I'm scheduled to get a new HDTV-capable cable tuner box from Time Warner tomorrow. I'm hoping that the component signal from the tuner box will be as clean as the component signal from the DVD player. If not, this TV is going back to Best Buy as "Not Ready for Prime Time".

Anyone looking to use this TV to view analog signals should be wary of this behavior. If I can get any smarter about what causes it or how to minimize it, I'll pass it on. However, if the new component-output tuner solves the problem, I may not really care much anymore.

Has anyone else noticed this behavior? Any suggestions on how to fix it?

A quick check shows that Samsung's not the only brand with similar problems, and that even $3000 monitors are not immune: http://www.avsforum.com/avs-vb/showt...&pagenumber=10

At any rate, I took a few pictures in case anyone is curious, and I'm going to try to attach them here (never done that before; hope I get it right). First off, ignore any horizontal artifacts you see. They are either the result of using the TV's "freeze frame" feature and catching a frame mid-scan, or else it's an artifact from the camera (catching a frame mid-scan). Only pay attention to the vertical artifacts. These captures are pretty accurate in showing how it really looks (i.e., very obvious in dark backgrounds, not so obvious in light backgrounds, and generally more obvious against solid backgrounds than varied ones).

Notice the pattern that is clearly visible on the "black" screen. Compare that pattern to all the other screens, and you'll be able to see it. It's as if there is a "brightness mask" being applied to the image.

(In case anyone wonders, I froze the image on the TV as the commercial started to fade out, which is why it appears so grainy.)

Yes I noticed these vertical bands when using s-video after a while as well. Did not notice with component input (but did not look too hard either). The old 3096 I was using had a stationary vertical band so I guess Samsung traded it in for two moving bands instead!

I returned the 3075 in favor of a trusty analog set. The bands did not really distract too much in terms of viewing but eat away at my brain knowing I paid $999 for this puppy and wanted it perfect. Sony models also suffer from a moving vertical band and Toshiba has horizontal as well as vertical bands to deal with.

Well these new digital tv's still have some bugs to be worked out. No surprises there. Cheers to the 30 day return policy!

Here's a short follow-up:

My new TimeWarner HDTV Tuner/Digital Cable box was delivered and set up today (Motorola DCT5100). The component output to the TV is, as far as I am concerned, flawless. Picture quality on the 1080i "demo" channel is fantastic. Picture quality on non-HD channels shows none of the "vertical banding" problems I saw last night. Black screens are truly black, and images look good from left to right with no visible defects. (Some of the pictures look "grainy", but I think that's just the digital aspect of picture reflecting analog noise in the signal.)

Before I got rid of the composite input signal "for good", I did a very little bit of playing around. I fed a composite signal straight from the digital cable box to the TV, bypassing the VCR. Picture was much cleaner, but there were still brightness variations from left to right (faint vertical bands). That's hardly a comprehensive test, but it's all I had the time and inclination for. It does seem to imply that the TV is capable to displaying a "clean" image; you just might have to play around to find the best method to get the signal to and into the TV.

Things worth trying that I never did: Feeding the RF signal into the TV via coax and using the TV tuner to display the picture. Using different cables. Using different input/output combos between cable box/VCR/TV (RF, composite). Using different input jacks at the TV. Etc.

Bottom line: This Samsung TV looks great wtih component sources. It *can* display a good, clean image from analog sources. However, that doesn't mean it always *will*. If possible, test your exact input signal path with the TV before buying it (probably not practical in a store environment). Short of that, make sure you understand the return policy, in case you can't make it work well enough for you.

I would be connecting this TV threw the coax connection, and then also feeding it a progressive scan feed threw the component connections, do you think I will have these bands? Thanks,

post #52 of 280
I honestly have no idea. I haven't had any problems with any signals sent to the component inputs (DVD on one and HDTV tuner on the other). I haven't tried the RF input...and wouldn't guarantee you'd have the same results as me anyway.

My best advice: Try it and see....

Thanks for posting information on your vertical line problem.

I had bought a TXM2796HF back in January and had this same problem. I set up a service call under warranty. The service company got in touch with Samsung...then samsung got in touch with me. They acknowledged that it WAS a problem...and that a "fix" was on the way, just backordered. Their rep was a true "customer service" rep...and was unable to offer any technical information on the issue. However, a very courteous, concerted effort was made to keep me a happy customer.

Anyhow, in exchange for the delay, they offered me an upgrade to a TXN model. I got it last Friday...and the same problem exists with the vertical lines! It is EXACTLY as you describe (either stationery...or moving across right-to-left- at times). My component inputs are flawless...and my standard cable channels (run through a splitter) are fine.

My issue is that my S-Video and Composite are coming from a ReplayTV 3060. It is through the Replay that the vertical line issue is the most noticeable.

However, prior to the Samsung, I was using a 27" Panasonic analog set. The vertical lines are not noticeable...however they do "faintly" appear on "rare" ocassion on the Panasonic when watching through the Replay.

Therefore, I am convinced that it is some sort of "signal interference" or "signal filtering" issue related to the type of signal sent from a Replay unit.

The technician that took the TXM2796HF noticed a problem with what he refered to as "low" signals (I should have asked for a clearer explanation).

At this stage, I have a call in to the same Samsung Customer Service rep to see what they say (or reccomend). I really like the set...so it is shame that this issue will not go away!

I'll post something if I get information from Samsung.

Any advice in the meantime is appreciated....

The vertical lines sound more like a grounding issue. Try one of the 3-prong to 2-prong ground isolators on the TV.

Mark
post #55 of 280
<quizzical look> Huh?

I'd be very willing to try that, but I don't understand what you mean. Like most home electronics, my TV has a two-prong "polarized" plug. So does the HDTV tuner. The VCR plug is not even polarized.

The only "3-prong to 2-prong" grounding-related gizmo I know anything about is the little geegaw you use to adapt a 3-prong (grounded) plug to an old-fashioned two-prong (non-grounded) outlet. I'm pretty sure that's not what you're talking about.

Could you please be more detailed in your suggestion?

Thanks,
Jim
post #56 of 280
Mark:

Did you mean the opposite? Adapt a two-prong to a ground plug? Those adapters are common.

It is an interesting idea worth a try; however, wouldn't I see this issue on more sources/inputs on the TV if this were the case? Should I try grounding the ReplayTV power first and foremost...then try the TV?

Lastly...an update from Samsung. The rep is still VERY helpful. I explained that this has not solved the problem. The rep said they were told that the TXNs solved the issue...but that it is possible that not all units had the "fix" put in (...maybe based on production timing...as the "fix" is supossedly fairly new?).

The rep said that the technical record indicates there is a system board replacment that addresses the issue. I'll try and find out more details when they call back. Anyhow, the rep is looking into whether or not this scenario is possible, and if so, they can get send the part and have a technician come out and try it on my new set. Maybe there is still hope!

So far, I am impressed with Samsung's support! They ARE acknowledging it as a "known" issue now...AND...truly trying to fix it.

I will of course keep you all posted!

Does the TXN line of widescreens accept and upconvert 720p to 1080i??
post #58 of 280
I can't give you a definite answer, but I'll say, "I don't think so."

All of Samsung's literature talks about their line of monitors accepting 1080i, 480p, or 480i signals at the component inputs.

The display mode itself is advertised as 480p/1080i.

My interpretation of all that is that you have three choices for signal inputs: 480p, 480i, 1080i. If you choose to input 480i, it will internally upconvert to 480p and display it as 480p. The only way to display 1080i is to input 1080i.

Maybe someone else can confirm or correct that for you.

Jim

PS: You see the sticky note at the top of this forum regarding the Monovision 16:9, right? I don't know about internal upconversion, but it says it can display 720p.
post #59 of 280
Actually, I think I read it DOES upconvert.

I either read this in the manual for one of the 27" 4:3 Samsungs...or saw it on a forum post around the time I got HDTV installed with Comcast.

Another way to check is to see if people have been viewing ABC HDTV broadcasts on the Samsungs...(as my understanding is that ABC only broadcasts at 720).

Lastly, depending on your HDTV source...it may be able to control the upconversion. I have a Motorola 5100 HDTV Tuner/Cable Box from Comcast. I am pretty sure it can be set to upconvert to 1080.

(I apologize if I am incorrect on any of this...but I thought I read it somewhere).
post #60 of 280
I had the TXN3075 and while I did not use it to view hdtv the salesperson told me anything above 480p is sideconverted to 1080i. I am guessing any new digital tv that can only display 1080i will convert any signal above 480p to 1080i otherwise you would miss out on half the hi def stations.
