Experiencing "temporary" burn in on my LCD--help please!

[Bluesmobile]

When playing DVDs, I see lines, shadows, images from previous scenes and shots remaining on the screen, especially in dark scenes. When I stop DVD playback, the shadow image of the last shot remains on the blue DVD screen. When I try to custom set my screen according to the THX Optimizer, the "temprary" burn-in is horrendous. Even on the factory settings (Dynamic, Standard, Movie, etc.) the temporary burn-in is there.

What is happening here?

I have a Samsung LNS-3251D
Oppo 981
using HDMI connection

It sounds like your contrast and brightness are not set correctly (too high). Get Avia or Home Theater Tune up and calibrate correctly. I do not recommend using the THX optimizer.

I have been turning the brightness and contrast down (to follow the THX Optimizer) and the problem gets worse when I tune those settings down. Is it too soon to take the display back and exchange for another, or call for service?

My Denon 2910 leaves a similar shadow image on the blue screen after I take a disc out. There is nothing I can detect when it is playing. I'm not sure if it is something to do with the player or the hdmi cable. It doesn't do the same with the component connection. Either way, for me it is not a problem.

It might be your dvd player. Does the same thing happen when you watch tv or vhs (if you have one). Do you have another dvd player you can try? Try a different connection type and see what happens.

I've tried 3 new DVD players (2 Sonys and the Oppo 981) and the problem is consistent with each. The problem is present when played through HDMI & component connections. I'm stumped, and at this point I am going to take the TV back for an exchange.

Yeah, taking it back is probably the best idea.

My Westinghouse does something similar occasionally (i.e. twice since I bought it a month ago), where it will get odd "blobs" of slightly lighter color in part of the screen. But it's only noticable when the screen is near-black. Once the display warms up, it goes away, or I can turn the TV off and back on and it'll be gone. I think it might be a partial input that's being received when the TV is first turned on, and gets "stuck" in the electronics somewhere.

But it should never be as bad as what you're describing. Especially when other TVs of the same make don't do it (I'm assuming the display model in the store doesn't do it, or else no one would buy it.. hehe).

The problem with display models in all of the stores around here (Best Buy, Circuit City, RC Willey) is that they all display HDTV through some kind of over-the-air broadcast, so the picture looks terrific. None of the stores will play a DVD for any TV they have on display, only select TVS that they have hooked up to a DVD player. For example, at Best Buy, I asked the kid if he would demo a DVD on a certain tv I was interested in and he basically told me no.

By the way, last night I upgraded to a Samsung 32" LCD with 5000:1 contrast hoping a new TV would solve the problem and no, it did not. Would a DLP rear projection display have any of these kinds of problems-because that's where I might be going next.

 

[Jedi2016]

Wait a tic.. a different TV did the same thing? You've got something else going on, then...

Especially if you're not noticing it on the in-store displays. A lag issue, or image retention, or whatever it's doing, wouldn't care what the source was.. it would do it with everything.

I agree with Jedi. The other possibility is that you might not have the DVD players set up correctly. I've set up various ones with my TV and sometimes there's just one little option hidden in the setup/menu screens that I have to toggle to get the picture to look right.

On another note... Best Buy and Circuit City should definitely let you try out your own DVDs. I'd try talking to the manager or supervisor or someone like that. Or, if you don't want to do that, try finding a store that specializes in home theater. While these stores are generally more expensive, they'll let you sample your own DVDs on their TVs, and then you can just go to the cheaper store and buy the TV there.

On the Sony DVD player, there are two options for reducing video noise: BNR (block noise reduction) and MNR (mosquito noise reduction). Do these features actually downgrade the overall image? On my Oppo 981 player, the recommended setting for their noise reduction is 'off', and when it is on (low, med, high settings) there are noticeable ghosts and tracers of images-very annoying. Fortunately, the Oppo player produces a superb picture that does not need a lot of noise reduction. I haven't been able to get rid of all of the residual image on some dark scenes, but I am satisfied.
