2008 Samsung HL61A750 LED DLP owners thread and FAQ - Page 113

My new A750 had an issue with convergence on the top as well as image bowing along the top. Techs came out last friday to replace the main board and the power supply, which did no good. I had to show them a convergence pattern to prove the issue, since their speel was it was probably the broadcast itself. Well, it is now in the shop to have the light engine replaced. Should be back in my house this Tuesday. I'll post pictures later of the problem. It was obvious that red and green were out of convergence from about the middle of the screen to the top, getting progressively worse as it got to the top. By worse, it was visible with normal program material, especially any top banners in sports programs.

You don't have to put up with convergence errors, though you may have to put up with some of the bowing if it meets Samsung's specs.

Just received my HL61A750 yesterday (phsyched), tweaking today, have a question: I'm hooking up my Denon 3930CI with HDMI for the first time (old Mits 65" RPTV had component only), should I choose YCbCr or RGB output? Also, once that is selected should I choose AUTO or 1080i-1080p? AND if I do use 1080i-1080p does that mean that the Denon is upconverting? Appreciate any help on this I can get.

Use YCbCR. Choose AUTO for 1080i/1080p.

No upconverting if it is all 1080. Just will decide on which unit will perform the de-interlacing of a 1080i signal.

"You don't have to put up with convergence errors"

Can the red lines around white letters be fixed through the service menu by a qualified ISF tech? Or do you need to have a part(s) replaced?

I ordered the hl61a750 last week but after going back to CC i am really doubting my decision. The ln52a650 seemed to have a crisper image and seemed to pop out more than the DLP (granted the tvs were switched to default (dynamic) settings). I will be sitting 8 -9 feet back. My other concern is that playing wii (6-7 ft back) standing up I will lose a lot of the brightness because I will have the tv optimized to be viewed from the sitting position. Any thoughts.

Disagree about the image quality...most showrooms have all the TVs running on torch mode and you can't really make a fair assessment there. Once you get this in the room it's going in and calibrated for those lighting conditions, it's great.

Agree about standing up to view it. IMO, the vertical viewing angle is the only real weakness of this TV. It doesn't affect me because I sit down even when playing my Wii, and I have the center of the screen exactly at my seated eye level about 8 feet back. If you HAVE to be standing up close and looking down at the screen, you're not going to be happy.

No they can't, if it is a convergence issue. Since there is only one DLP panel inside, and it is in a fixed position, there are no adjustments for convergence. The alignment of the whole grid can done, but by moving the light engine only.

Call Samsung and discuss your problem.

Mine has a very subtle red around white letters if I stick my face right up to it, but at 8 or 9 feet (even at 6) you can't see it.

I'm wondering if it's even worth calling Samsung from the threads I've been reading saying there is a small amount of tolerance as you move away from the center.

Could this problem be caused by something other then a convergence problem? And if so, what other things could be causing the red around the white letters? Thanks.

You'll have to zoom in on the pic, then scroll down to see that the coveregence comes back together from the middle down.

My Samsung Convergence

Damn Lee, that's off by a bit...You can't notice it in pictures sitting 7-10 feet away?!?! I got someone who is willing to buy my Mits 55 HDTV...I'm beginning to wonder if I should just have an ISF guy come in, and keep it. What you guys think?

i can see some convergence errors on the 67" from 2" away but from my viewing distance the tv looks perfect,awesome picture not going to have it repaired or anything

I do notice it, and I sit about 14 feet away.

From here forward the end credits have added red to them! ha ha

I'm so on the edge now! I've seen it on every floor model I've looked at, and it's showing up on the boards... Man, I don't know what to do. Buy or wait for something else to come out?!?! God, I can't go below 55 inches, it's sacreligious, or something.

Seriously, it's 2008, and we all have to worry about convergence problems in tv's! Did we just add color to the tv in the last 10 years?!

The more I read about these problems the more I want to go back to looking at plasmas, but I want the size of my old 65 crt. I cant take a gamble on $1800 worth of tv.

Hey Fellas--

I've pretty much decided on getting this, but I'm gonna be waiting just a little while before I pick it up; I'm hoping that there'll be a price drop in the next few weeks due to the economy, or around black friday. But what I realized is that it just wouldn't do that have the tv delivered with no stand for it to sit on!

Can you guys give me some recommendations to work off of? Honestly, it doesn't have to look great, just fit a center speaker and have some decent airflow (I'm taking stability as a given). My biggest factor is the price; I'd ideally like to spend as little as possible. So far, my research has yielded these results, but I would love to hear any other ideas!

Costco

Sam's club

Ikea

Target/Amazon

I'm sure that a few of these are inappropriate for the TV; please feel free to point out which and why.

Thanks in advance!

You can try, but the tech told me convergence issues have a huge amount of play on DLP's. They won't do anything about it unless it is horrible.

Would someone please measure the width of the base of the 67 inch unit? Thanks!

I'm using HDMI with a Denon 3808 and I think you are better off running straight straight thru the Denon, stripping the audio and let the 61A750 do the upconverting

It's not square, so it's a little hard to get a tape on it, but it's about 39 1/2 inches wide . If you allow 40, you should be fine.

It was my understanding that game mode was there to reduce input lag, or is this not true? But yeah, I probably wouldn't end up using it anyway if the picture isn't adjustable and looks bad with the defaults.

I tried a second extension, and it worked fine. I guess something was wrong with the first USB extension cord.

Exactly! Game mode bypasses a lot (most?) of the additional digital processing to reduce percieved lag from a gamer moving something and it happening on the screen.

So you can't have all of the adjustments since you are bypassing that portion of the electronics.

You would then use your source (i.e. the game system) to adjust your brightness, gamma, color, etc.

It's not on all of them. It is not on mine that I can see. Are we to the point now where the TVs we get are supposed to look perfect with your nose pressed to the screen? What is the big issue if you can't look see it at your normal viewing distance?

I will say I went to another store today, and looked at the floor model of the 61 and there wasn't a convergence problem on that model. Verrrrrrrry little but I had to be 3 inches from it. That's a good sign!!!!

Gonna get it, and if the convergence is bad, swapen it out!

I can see a little red with my nose an inch or two from the screen but from 8 feet back--no way.

As an aside, does anybody know what the inside of the screen is made of, i.e. reflective material. With a full bright background, it's very even, but you can tell it's projected on a surface.

Quite honestly, I wouldn't choose any of them.

Costco--Not enough component space if you have a Center speaker, AV Receiver, Game system(s), DVD player, Sat/Cable box. Design is far too "open" with no wire management system. You'd have wires showing all over the place.

Sams Club-- Where would you put your center speaker? You can't put it in the cabinet, unless you want to leave the doors open every time you watch a movie. On both the 61" and 67" setting the center speaker on the same shelf as the TV usually doesn't work, as it blocks the IR signal to the TV.

Ikea-- Doesn't seem to have any way to connect components together, without punching holes in each of the cubbyholes. Plus, if you'll forgive my candor, it's butt ugly.

Amazon/Target-- Is this thing made of plastic? Shipping weight 78lbs, but only holds 100lbs? The top shelf doesn't look deep enough to support the 61" or 67". Also there is the aforementioned lack of component space and problem with the center speaker. It looks like the one shelf is too low.

Here's a link to the stand that i have my 67" sitting on. The base sits on it just fine. The edges of the TV extend past the stand about 2 inches on either side, but it's no problem at all. If you're going with the 61", then it will be even less "overhang". It's a little pricey (I paid $349, not from this site) but if you're gonna shell out between $1600(61") and $2000(67") then it's worth the investment to place it on something that's going to compliment it, and not detract.

I have the same Z Line tv stand with a slight variation to the design, but bought from target for $200 I think it was, very good stand. I am currently using it with a 56" tv which fits perfectly fine.

here's the link http://www.target.com/Balboa-Park-TV...%20line&page=1

I know you want to keep it cheap but you are going to spend a good amount on the TV might as well pick up a stand that will support your TV and components as well as look nice.

I picked this up from Amazon for $530 September 30th unfortunately the price jumped back up to MSRP. My 61 is centered nicely and has four inches of side clearance three inches out back and two up front. The center shelf is adjustable allowing anywhere from 7.5 inches of clearance up to 9.5 inches of clearance. My Bello stand is setup for the latter as the center channel is fairly large. My PS3, Denon 2809 and DVD player stacked on top of my DishPVR sit on the bottom shelf with three inches of clearance between all components and sides. The tallest component the AVR has 2.5 inches of clearance from the middle shelf above the AVR. I hope this gives you an idea how your components will fit. Cable management is decent cables cannot be seen, plenty of air circualtion all around.

I was going to go the same route as you. Ini the long run I saved my cash for two months before grabbing this stand. I am very pleased, the wife likes it and I have gotten some nice comments. It took an hour and a half to assemble and is very stable. Delivered weight is 210 pounds amazon lists it at 150 pounds!
