My OTA tuner changes channels immediately, menus are also are normal in speed. Try disconnecting the internet and see if something with that is causing a problem.

Well it appears there is a problem with 4.31.34. If there is a way to roll back I guess I need to find it. Not going to try the "Brit" method as I think it may brick my unit. I know on some devices, changing the firmware revision number in the file name to a higher increment will fool it into flashing. Before I do anything I want to make sure it has been done before with no problems. I'm not rich and I've just spent a lot of money for a TV that I don't want to "experiment" with.

Now here is the problem that 4.31.34 has created:

When I play a video file or a picture using the Smart Share All Media, and it doesn't matter if I select All, Photos, or Video, I get a screen full of yellow static looking lines. Sorta like the "snow" you would get on the tuner if there were no antenna or a empty channel. On a video it lasts only for a second. With a picture it will stay on screen until you do something with the picture like rotate it or change pictures.

Is there a way to do a full factory reset? Like a paperclip hole reset button someplace? Or a key press combo? I'm not worried about having to setup the TV again. I know with a lot of devices I have, like a WDTV Live Hub, if you factory reset the unit after a update it seems to get rid of the some of the problems.

Here is a screen shot! (A picture is worth a thousand words)

4.31.34 Bug
post #2853 of 3924
Is it worth doing anything with the software that will brick the TV for that feature of the TV? Otherwise the TV is working correctly, I would let it be. Since you do not have the most recent software yet, no doubt it will download at some point. (04.31.43) And most likely there will be more to come. I actually get that every once in long while when I click on the test pictures in the menu. If I turn off the TV, then turn it back on the pictures work again.

In this day and age it is inconceivable to me that there would not be. Remember, LG needs to protect themselves from the on-site repair guys from bricking things too, and then covering themselves by blaming the whole panel.

Given all that has to go into the TV in the first place, a backdoor is the easiest thing of all. Remember also that they have to protect themselves from accidentally issuing an online update that itself bricks the bejeebers out of the devices.

That said, I spent a long time looking over the netgear forums because they themselves bricked their routers across the world in a way that prevented further fixes online. They were in quite a disaster mode for months. Perhaps they were lax because of the fact that it's a $99 item, and not a $1500 street price item. I don't know how it resolved.

And yes, I had to rewrite this @#$%ing post 3 times to keep the backdoor discussion from sounding like porn.

What's this here "brick" I keep hearing about? Is that when a software change makes the hardware in-operable? Isn't that imposible since hardware is read only, save the writable memory? Either way, in the netgear case, couldn't they have just rolled back?

Aye, a "brick" is precisely that. When a software change renders the hardware inoperable.

As for rolling things back, you'd be surprised how often that option isn't available.

As for the LG TV in question, I'd tend to agree with you, but I wouldn't want to be the one who's taking the chance. :P
post #2857 of 3924
It's nothing like what you are saying, no. The device stops responding to the software commands, hardware is fine. What do you mean by "Rollback" - Like Walmart rollsback prices? No. An upgrade to a complicated device can be very hard to undo. That's why companies update or "patch" instead to fix what is wrong.

I do agree with tgm1024 - there should be a factory reset. That is very different than a software downgrade.

My girlfriend and I are going back to Futureshop to return the plasma we bought the other day. We felt it was too glossy for our environment. I was curious if anyone has had issues with reflections or glare from this TV?

We have two lamps which provide the majority of our living room light 9 feet in front of the TV. Each about 15 degrees off center from the TV. With this set up are we going to get the same issues with reflection and glare? Are there calibration settings to account for this?

It can be difficult to understand if you're not a software engineer sometimes. In a nutshell, there are two things going on: The software "embedded" in the device is infact something called "firmware". Why? It exists between hardware and software. Think of it as software that becomes permanent until more firmware comes along. (It won't go anywhere by pulling the plug).

Second, imagine this if you can: In order for the machine to update firmware, it needs to access the web or the USB key. Computers are odd this way----it's actually software that does that. Working software is required to update itself. That software ceases to function, and you're SOL (unless there's a backdoor).

Computers in general follow this very principal. How do you run a program? Another program (called an operating system, or "OS") has to be working well enough to lift it off the disk and run it. How did that OS start running then? By having bootstrap software (usually in flash). The term "booting a computer" came from the very catch-22 notion that computer software must somehow "pull itself up by its own bootstraps".

Absolutely everyone on the planet that has this device has either complained about it, mentioned it, asked about it, or noticed it and winced. Perhaps an overstatement, but not by much.

2012 really seems to be the trending year of reflective surfaces. I think we'll see dramatic changes to this concept in 2013, and in the coming years. It came about because a mat-screen has the ability to diffuse and "un-sharpen" (albeit extremely slightly) the image. It goofs with the contrast as well, but I've never been clear on why that is.

It reminds me of why car manufacturers under-inflate the tires on their vehicles: to increase the specs on the skid pad, despite the fact that IRL it eats up the tire horribly and can give you a "wallowy" feeling.

The proper way to watch TV (try this immediately if you haven't) is with a dark room and a light *behind* the TV. You'll hear people refer to this using what I consider to be odd terminology: "Bias lighting", or "Biased lighting". As a very quick experiment that you'll appreciate, tape a small flashlight facing upward behind the screen to see what I mean. It does not have to be evenly lit all around for you to see a very comforting effect. Many people accomplish this by simply buying an "LED Rope Light" (those weird lighting strands encased in a flexible clear plastic tube and positioning it in a loop around the back of the TV.
post #2861 of 3924
I had posted a couple of days ago, regarding edge bleed, which is something I've not yet adjusted to. There are 2 Frys in the Atlanta area. I was in the vicinity of one today and took a look at the LM7600 demo unit. The demo seemed to have basically zero edge bleed. Granted, not a pitch black room, but this was in a very dark area and I turned off the other TVs across from the demo to make it as dark as possible.

Here's the question.....since this is an LED tv, would it be incredibly stupid to exchange the TV I have for the demo, if I can determine with certainty that the demo does not have dead pixels or edge bleeding like my current set has? It's not like a plasma, which seems prone to problems sitting on display for a while....correct?

It wouldn't be "rolling the dice" on another unit in the box; on the other hand, I would have to inspect closely to ensure no physical damage to the case or screen.

Assuming it comes with full warranty, what difference would it make if it has a thousand hours on it or so?
post #2862 of 3924
Agreed, the 7600 is a glossy SOB. More reflective than the Samsung glossy it replaced. That said, its not a deal killer for me since it faces away from the window and I usually watch TV with the lights off. But your milage may vary.
post #2863 of 3924
Long time listener and wanted to put my 2cents

After trying lot of different tv models and brands finally settled with 47LM7600. Tried 3 LG sets and all came with different issues, too bright areas, too dim areas, dead pixels and all of them came with clouding and flaslighting. Finally got the 4th set with no bright/dim issues but heavy flashlight/cloud issues. Thanks to slim bezel i was able to fix the flashlight/clouding issues by playing around with the panel.

Here are the images with backlight at 100% and local-dimming OFF. All the other settings were the same.

BEFORE


heavy flashligting on top


heavy flashligting on top


Kinda blur, but gives a nice idea about how bad the screen is

AFTER


Black bars are damn good


edges are much uniform, halo from my bad phone cam


Whole screen is much uniformer even at local dimming off and 100% backlite


Yay!...No flashing on edges at 100% backlite and local dimming off.

I was able to fix (atleast 95%) the issues of the clouding and flashlight on all the sets (4 set including what i have now).
post #2864 of 3924
Can you post an image of yours?, what settings you have in your set?, The demo unit could have local dimming at high. Regarding to your question, although LEDs are also aging, 1000 hours or so have a negligible effect comparable to its lifetime.
post #2865 of 3924
Would you say it is glossier than a plasma screen or less? We were almost OK with the plasma.

As for the lighting, our options are fairly limited due to the size of our living room and how it has been designed. But, we can certainly move some things around if need be.
post #2866 of 3924
Avsrosh,

If you asking me for an image, I posted an image on the previous page (95), post #2839 of this thread. I probably shouldn't post it twice.

How were you able to "fix" yours? Settings? Or some other adjustment to the physical panel itself?

cderrick14

Can't you do anything with those two lamps you mentioned before. Different shades? Different bulb type? Moving them? Also, not sure if their recessed or not. If so you have a lot of options there.

The glossier screens are more of a nuisence. But worth it imho due to improved contrast and sharpness.

According to your image its bad enough to return the set. However there is no guarantee that you get a better one. All the 4 sets i tired had similar to yours or worse. If you really wanna try the demo one, you can take yours there an check yours with the same setting at the same place. Im pretty sure that the demo one has the same problem.

I dont think these tvs have this much of flashlight when the come out from factory. These tvs are not packed enough in the box to secure the panel during the transit. Unlike the other tvs, this thin bezel screen is not well protected by plastics frames or glass. So easily the the pressures (distance) between layers of the panel changes a lot during the transit. I do these these changes if you move your TV place to place by carrying. The bezel is not strong enough to handle those forces.

Back to the question: Non of the settings or calibrations can be eliminate this issue unless you wanna put local dimming high and lower the brightness unacceptably. I physically did adjustments on the panel itself. if you are extremely patient and careful i would say it would not void warranty. I know lot of people will hammer me regarding this mad.gif(like people did here to a guy who was trying to roller the screen with a paint roller). But again i was able to fix 4 sets with no any issue. Let me know if you wanna try that.

I think there is a place in the settings where you can read how many hours of use are on the panel. So you could actually know how many hours on on the set before you decide. But consider, 1,000 hours in a home environment might be 9 months to a year's worth of viewing (3 hours a day). 1,000 hours in an electronics store is likely only two or three months. And the 7600 had been out for over a year now, right? I bet that demo at Fry's has 3,000 + hours on it. I wouldn't want that. Also, how are you going to transport it home?

I'd like to know. I've had temporary success in alleviating the flashlighting on my set by using light finger pressure on the bezel. But it would always revert back. Would you mind posting how you cured your set? If you prefer to PM that's fine with me.

Hello everyone, just wanted to check with you guys on these two HDTVs:

47LM7600
55LM7600

These HDTVs got a great score on my website for input lag, rated at 34ms and 35ms respectively under the "Game" picture setting. This is using Leo Bodnar's Lag Tester. I just wanted to check with you guys to see how your experience is with gaming on this HDTV. Thank you!
post #2873 of 3924
Hello to everyone!

Let me tell you my problem. I bought the LG LM7600 but I didn't know that was blocked the time machine option. I already checked information about how fix this but I am not sure is it possible with this model. I would like to try with a universal remote control to access to the EZ adjust but I don't know which one works fine with this tv. Would be great if you can suggest me one from radioshack to buy it and then return it if doesn't work. Thanks a lot for being there!
post #2874 of 3924
yeah,36" and we look up a little bit..any more would be too much for us. When we mount on the wall we will tilt down a bit 6.gif

What remote has been asked and answered over and over, just do a search on this thread for a full answer. So has the question of that option. You can't do what you are asking, period.

Two teenage sons claim it is practically lag free. I should know because they made me hardwire the PS3 to the router to eliminate the inherent lag in wireless connection.

If you want to someday, know there's nothing wrong with posting an image twice. The way to do it and be guaranteed it won't cost anything in bandwidth is to have the first one loaded in to avsforum, and then use THAT image in subsequent uploads. Have the 2nd one refer to the 1st by link (instead of upload) if you want to make sure AVSforum doesn't accidentally duplicate its own stored image.
post #2879 of 3924
BTW, the new LG's have a redesigned remote which works roughly the same way but was purportedly going to have a querty keyboard on the underside. I wonder if that'll work with 2012 TVs......
post #2880 of 3924
That remote has been out for two years, comes standard with the Google LG TV. It works with any of the newer LG TV's like the 7600 that allows for qwerty.
