Grainy picture sometimes I bought the samsung ln46b550 TV recently and hooked it up with an HD box from comcast (using an HDMI cable).When i am watching the NBA games on ESPN HD channel, the darker parts of the screen look a little grainy, i am not sure if grainy is the right word, but i don't know how else to describe it.For example, when ever they show the crowd (and the lights are off on the crowd) the picture is grainy. The picture looks great on the brightly lit floor. When they show a close up shot of someone shooting the free throws, the crowd in the background looks a little grainy.Does anyone else observe this? Is this common? Could it be a problem in the source or a problem with my TV?

Your right on the money!! Mine does the same thing and I hate it. I was also watching the NBA playoffs and noticed and then it happend when a commercial was on and now I notice it all the time. My 27 1080i LCDTV Olevia has way better quality in HD and SD. I was using HDMI then switched back to component cables. One thing that did help me though is that I turned off all the special settings like the enhancements and black levels to get a true picture, because the manufacture hikes up the settings to make the TV look better on display at the store than in your house which will look a lot different.

I think we're experiencing image burn-in on our 2 1/2-year-old 1080p LCD TV. When an HD show is on, there are now visible vertical lines marking where the sidebars of standard definition programs would be, almost as if a standard size screen were placed over the widescreen. There's also some shadowing in the top half of the standard screen area. This is most noticeable when the picture background is light colored. We had no idea this would happen. We were considering buying the Samsung model you've got, but we spend more than 5% of our TV time watching standard definition programs, and many of our DVD/Bluray movies have black bars on top and bottom. Maybe we'll just get by with our current set until the image burn-in problem is eliminated.

HD is so good that it is going to magnify low resolution and you are going to see the defects. The best way to minimize this is to not stretch programs that are in the 4:3 ratio. Go to HOME, SETTINGS, SCREEN SIZE and then set 4.3 default to "Normal". If you set it to anything else, it is going to stretch the screen and make things worse. Also make sure your cable box is set correctly because you can change how it outputs from the cable box. The third thing you need to watch is to use the correct mode with the correct program. For example, the vivid mode can cause eye strain. Reserve this mode for the simpsons and other similiar animated programs. Use standard for standard programs. Use cinema or customize the setting for sports. If you picture is too sharp for sports, you are going to see a fuzzy screen. If you reduce the sharpness and the brightness, the picture will look smooth and give you a better sense of motion. Also, even though it has nothing to do with the picture, be sure the crank the voice boost feature and the sound is incredible when you do this. Hope this helps.

I do not have this problem. If it is only during sports shows, it is probably the settings not a defect in the TV.

One of the posters talks about the picture quality while using non-HDTV. I think he said he has it in a trailer, so no HDTV. Also, this unit doesn't have an S-Video connection, which is what is needed to get the best quality standard def. picture (at least that's my understanding). Which tells me that this unit is really not intended mainly for standard def viewing. Vizio, Sharp, and Philips make some units still with S-video connections. Maybe some others do, too, but so far I've found only those three brands. And if I had to guess, I would guess that eventually they'll all stop putting in S-Video connections, as more and more people start subscribing to HDTV.

I just bought Vizio XVT473SV from Dell, which was delivered last week. Worked fine for a day or so, but I'm noticing some screen distortion/flickering occasionally. Also some audio cut-out. Some posts suggest this might be standard def vs HD channel issues. (cable) I've not had any indication of visual or audio problem yet when using the Internet Apps or when hooking up my laptop to it. But it doesn't always work right when I turn it on with it tuned to the cable box. The problem this morning with flickering was a situation with TV/cable turned on, cable tuned to a standard def channel from the night before. I tuned to an HD channel, the screen still flickered. I turned off cable and tv. Turned back on and all was well. I'm not happy to be seeing these kinds of problems within a day of having the tv though.

Unless you received a defective TV it sounds like a setting needs adjusting. Have you looked at the output settings on the BR player? Also, are you connecting it via HDMI? Other cables will give a lousier image. Also, you may need to adjust the color, contrast, etc., settings on the TV to make it look better.

I am having an issue with my 5400. Worked great out of the box for about 3 months....Then the video started flickering, then would go black for about 5-10 seconds then come back. (very annoying when watching sports!). anyone have any ideas?

I just want to know if their is any pixelization during sports. I have a 52 inch samsung lcd 60htz and it get choppy during fast action, does this tv do it too? or does the 600 htz take that problem away?

are you sure that the cable box is HD? kinda sounds like it is SD? the other thing to remember is that not all stations are being broadcast in HD and even then some local channels might not be broadcasting certain shows in HD. for example, my local stations might broadcast a golf game that is in HD, but the local news is broadcast in SD.As for the tv itself, i'm not sure. I'm waiting to get my 4053 delivered and i'm having a hard time waiting! you might want to check your connections again though.

No issues here, been using for 7 months now. However, I noticed one day my HD was horrible quality, and it started freezing and jitters. I tried to troubleshoot it all around on the TV settings and no luck, then I did a reset on the HD cable box and it was fixed!

So its not really 120hz or... what? I just bought the LN40C630, and I notice a lot of juddering still, like its not really working. In the store compared to the other tvs this one looked great during action scenes, but now that i have it in the house, i swear this thing is just as juddery. I messed with the settings for auto-motion and it seems like it may have even gotten worse *confused*....

I recently purchased the LN32A450 and have used it only with the cable feed and the most basic of packages from Comcast(no cable box). All of the unscrambled network broadcast channels(CBS, NBC, FOX, PBS, etc.) come in HD and look great. The rest of the channels are SD and look good, especially if I view them in 4:3 format. The problem with doing that too much, however, is the risk of "burning in" because of not using the entire screen. The alternative is to view everything in 16:9 and putting up with the stretched faces, etc. The SD broadcasts are, in most cases, just as watchable as on my Sony Wega 27" analog TV. But with an HD signal, as you might expect, the Samsung really looks great!

I own a Samsung LNB630 and am a Comcast customer. It is hooked up directly via the coaxial cable without a box. I receive the major networks (ABC, CBS, NBC, PBS) in HD just fine. However, if I want to view most other stations (for example CNN, ESPN, USA, TNT etc.) I must watch on my old analog set hooked up via a Comcast digital converter box.

It definitely depends on your receiver and how good the channel transmits their signal, but I would say the picture is excellent when all things are considered. I've NEVER been overly blown away by ESPN/ABC's picture quality; however, NBC has excellent HD and last Saturday's Wild Card games for NFL looked great.Keep in mind that HD receivers only transmit in 1080i...no TV is going to give you bluray quality (unfortunately) at this stage. I'd say it's definitely comparable to TVs with a higher price point and equal specs.

I have never had this particular problem. Occasionally we have problems with it pixelating, but that was our cable/dish service-not the television.

When I tried using the composite upconversion for the Wii, the picture looked terrible! It was very grainy and there were bars on all 4 sides. I have since bought a componet cable for the Wii and the picture quality is much better but there are still bars around the picture. When the Wii is connected directly to my 55" Sony LCD, it looks perfect. I called Sony support and they thought the receiver was defective so I exchanged it for a new DH820, and had the same results.
