backlight in the 50s? wow. Ill try it but I think it would be nothing more than a 55" nightlight

mines at 95 currently with contrast at 85. I dont get any flashlighting with Local dimming on High. Though I moved it to medium b/c on some dark black areas like people clothes, details were lost b/c it was too dark

Can you post your calibrated settings? I've found 50 to be very dull for anything other than pitch black viewing, bright sunny afternoons or early evenings with a light on need the back light turned up for me.

If you could post your calibrated settings I'd like to test them if possible.

I change my backlight setting depending on day or night. Day time around low 50's, nighttime around low 30's. Brightness never more than 50. Contrast can go to 100 if you like. Perhaps use 1.9 gamma if it's still too dim for you.

I agree with Marty. I use different backlight settings for day and night. Low 50's during day and low 30's at night. Brightness never above 50.
You can set contrast to 100 if you must. If it's still too dim for you. Use a lower number for gamma and medium dynamic contrast will give you a bit more "pop".

so after doing a return order on amazon for my 55LM7600, I took a trip to Fry's Electronics. I'm must say I fell for the LG 60PM9700 plasma. I like LG, I wish I can have a passive but reality I'm looking something bigger then 555. I think I will jump on the plasma wagon.I never seen a plasma with a matte screen.

This is my "Drapes Closed" setting. You can always set up a brighter preset on Expert 2. I believe that is what they are there for, day and night ISF slots.

Here is what I have so far for my Oppo BDP-93 player using Source Direct out of the Oppo , hitting my iScan Duo processor for upconversion and then in to HDMI 2 of the LG.
Using a starting point from the professional calibration done by the flatpanelshd website I dialed mine in more with the Speers and Munsil.

Picture preset: Expert1
Backlight 50-55
Contrast 91
Brightness: 50
V/H Sharpness: 10-10
Tint 0
Color 55
Dynamic Contrast Off
Super Resolution ON or Off (I find with Standard Def material it DOES have a noticeable effect)
Color Gamut Standard
Edge enhancer Off
Color Filter Off
Noise reduction Off
Mpeg noise reduction Off
Black level Low
LED local dimming LOW or OFF. (higher settings seem to introduce artifacts such as banding and make flashlighting MORE noticeable rather than the other way around. You may not agree and wish to use more of it)

TruMotion Off This panel has a native 120hz refresh rate and achieves 240hz with the aid of a quick and imperceptible flashing backlight. Tru Motion is NOT required for 240hz. It is for motion enhancement ONLY and will not affect your actual refresh rate at all. I hate it and leave it off at all times or things start to take on the dreaded 'soap opera' effect!
Color temperature Warm
Gamma 2.2
RGB Method 2 point
R high -6
G high -11
B high 18
R low -1
G low -2
B low 4 (to adjust the color temp this way you first go thru the RGB High, then toggle to Low and go down the list again. Then when the TV prompts you to "apply to all inputs?" I clicked YES so all my inputs had the same color temp.)
Finally, while this is a decent starting point towards a good calibration, it is NOT the end all be all. You may not like how things look at all at first and might require a while to get used to it. The out of the box settings are lousy compared to what can be achieved with this 7600 and the great control software LG offers which of course is built right in.
Once you get these settings in, then play mainly with your brightness and contrast and in SMALL increments. Normally the higher you put those controls the more you may need to boost the color. ALWAYS keep the back light lower than the contrast to avoid clipping the display and running out of dynamic headroom for fine adjustments. Sometimes it is MUCH BETTER to lower things, than to raise them. Less is more and a little goes a long way!
GOOD LUCK! Cheers! Marty G

***** ALSO, once you get your night time settings correct, it is very easy to do your day time settings. This can be accomplished by simply RAISING the backlight (it needs to be down enough in your night time settings to begin with, so you have something to raise) and doing so will increase ALL the other settings such as contrast, brightness and color exponentially on a sliding curve. VERY handy for only needing to do a major calibration once. Give it a try. I did a load of research and all my sources said that is how the controls would respond, and after using them myself I agree. Of course a small amount of tweaking for day time such as perhaps using the dynamic contrast on LOW might give you the push you desire. It screws up my overall gamma so I never use it. Once you get to know how the controls and panel respond to adjustments, setting it up for a really great picture becomes easier and easier. Good luck!

I just picked the last one up from Best Buy in the San Diego area yesterday and it looks awesome. However, I will be swapping it out because of flash-lighting in the bottom left and top right. It is very noticeable when watching blu-rays that have the black top and bottom bars. Even with LED Local Dimming on it is still visible.

I will have to wait until Tuesday to get the new one delivered from the LA warehouse. Hopefully I get better luck with the new one. I am fine with some back-lighting, but this is just too much. I guess it really is hit or miss with these new TV's. This is my first LED TV, previously had a 42LD520, but that seems to be pretty terrible compared to some other pictures I've seen in reviews. I am using the exact same settings as the flatpanelshd review and you can directly compare it to their bleeding/flashlight test (which is much better, although not perfect).

First picture is with LED Local Dimming Off.
Second picture is with LED Local Dimming on Low.

yeah thats what I was seeing with my first 7600.

The second one was better (or maybe my settings just minimized it )

I do have Local Dimming on Medium and I mentioned earlier theres no visible flashlighting with dimming on high.


Im curious why this is so prevalent. What in the manufacturing/engineering of these sets allows this? wonder why its almost always in the same 2 corners as well...

New owner here of the LG LM7600. PQ is fantastic, but there is a terrible amount of flashlighting in all 4 corners. Needless to say, it will be sent back. LG I hope you are listening.

A few years back I followed a Samsung thread (don't remember which one). As I recall, the info was from a Samsung Tech who indicated "flashlights" resulted from slightly mis-torqued screws that hold the LCD panel to the LED-edge-light frame. The panel gets ever so slightly deflected near the hold-down screws and the light diffuser deflects too much light into those areas.

It happens at the corner edges because thats were the screws are and because the corners are easier to deflect than the edge-centers. The fix for many was adjusting how tight those screws are.

To me this makes a lot of sense and explains the random appearance on one set but not another. All the components are fine but the assembly process is just a little off spec.

If anyone has this problem, I'm curious if pushing on the corner of the screen makes it worse / better. There is probably a very simple fix but I have no idea how to access the mounting screws. I'm set up for delivery on the 30'th.

Hmm, makes sense.. I might try it out later. I'm getting a new one delivered tomorrow though. Honestly though, these things need better QC before being sent out.

Does the browser support flash?

Yes, because of this I can access sites like cbs.com and watch past episodes posted on their site, but I can not go full screen with the video. I can not access crackle.com though and that is a bit of a bummer.

Thanks.

I tried that already. Didn't help me at all. I saw the same information couple months ago in 65LW6500 thread. IT worked a little in that TV but not in the 7600. At least nor for me

I'm using calibration settings from this link.
http://reviews.lcdtvbuyingguide.com/...-settings.html

At night 41 for backlight seems fine but during the day I've gone as high as 60.
TruMotion I set to "Off" don't like that soap opera effect.

Local dimming I set to "Low" that helps with bottom left & right "flashlight".

It helps, but as you see from the pictures above, it is still very visible. I just watched some Game of Thrones, and I could totally see it (and that is fullscreen with no black bars).

Hey apoklyps3: Sorry for the delay, I finally got to upload the pictures for the lag test. Here you go : Lagtest

My previous post as a reference:

thanks alot man. seems proper test to me. 0 lag, seems great as PC monitor. wondering about 4:4:4 chroma subsampling .can you test for that too? you'd be my hero hehe.

Yes......i watch all my porno here.....lol

I think something is going on with the production of the 7600. Amazon is now from 1-2 months shipping time. I think LG became aware of the issues and has stopped production until they get fixed

could be they are selling them... i know around my area they have been doing great. people love that thin bezel. not everyone has those problems or is as critical i would say.

mine has been absolutely great so far 3 weeks i've had it

The 47 is still showing in stock from amazon to me, but at $1500 and not the $1279 I purchased it for on Saturday. I just set up this tv a few minutes ago. I haven't calibrated it yet. I ordered the 47 from amazon and was dreading this flashlighting problem, but I am happy to say I don't have any out of the box. I have only had it on for about 15 minutes on an hd channel though and have not popped a bluray in yet. Can the flashlighting appear later even though I see no signs of any yet? I'll post some updates later.

Amazon regularly puts a shipping delay on something that sells out quickly. Speculating that LG has stopped production because Amazon quickly sold out its first lot is silly. I think LG is just beginning to ramp-up production and get these into sales channels.

It would take a lot more than a handfull of AVS complaints to shut down a production line. It's fun to think that they stay up working late hours to make perfect TV's that satisfy AVS readers. The simple observation that no one from LG's production/engineering/consumer relations/corporate divisions contributes here, speaks volumes.

Well I just got the new one in, unfortunately it is having the same issues. The top right is fine now, but the bottom left is worse. Should I just keep shipping this back or is there another TV I should swap it out for at Best Buy? I was thinking of just upgrading to the 9600, but I haven't seen it listed yet.

I'm pretty sure it wouldn't be the AVS forums who LG would pay attetion to, rather the amount of returns they are receiving.

Well, I'll bet the 9600 will be a nice set but its also going to be quite a bit more $$$. Maybe its just me but it seems the high pricing for many of these sets is not reflected in the inconsistent quality, design flaws, firmware problems, and poor customer support.

If my set has issues, I'll just return it. I'm not going to be LG's quality control department. Did that with Samsung and just gave up. Maybe I'll just wait and see what Apple has to offer.

Can somebody help me my tv is like lip syncking.....sound and lip is out of sync

There should be an AV Sync control in the audio portion of your menu.
There is a lever to move back and forth until the audio matches the
video.

I just got off the phone with Best Buy and will have my replacement 55lm7600 next Friday. Hopefully the flashlighting is no longer a problem with that set.
