Official LG xxLD550 xxLD520 xxLD650 Owners Thread - Page 115

To me, the warm setting is much further from 6500k than medium. I'm not sure how yellow 6500k is supposed to be but I dont see much, if any, of it in the 6500k bias light I have behind the TV. Maybe you're right and my eyes are just so accustom to excessive blue that proper d65 looks overly yellow to me. Right now I just can't see it on my set - I'll be interested to see what the meter tells me when it arrives.

That's really odd because I don't see that all at close viewing. Normally we're about 10' away and either 1' to about 5' off center and the pic is fine. When I walk past the tv, usually about 2' away I don't notice anything. I think there's just some inherent differences even within the same IPS family of panels.

@Phase -

Have you updated any of your settings? I think I've sort of lost track where I am with the current set and would like to "reset" my baseline settings if need be.

I finally got the first phase of my 47LD520 installation finished today. It'll stay like this for quite a while I imagine, as the next phase requires moving a gas line in the wall right where the left in-wall speaker will go.

When I first got my TV, I mounted it to the wall, then added some simple shelving brackets to rest the speakers and components on, but none of the cables were run in the wall. Here's how that looked:



It worked, but it was messy and ugly.

Then I removed everything and laid out the locations for all of the wall plates, behind which all of the various cables would be run. I also ran 2 power lines to a dual outlet, one always hot for the TV, and one run through a dimmer switch for the rope lights I would attach to the back of the TV. Here's how it looked after I had all of the gang boxes in place:



Here's the current look with everything back on the wall, all cables hidden either in the wall or in the custom storage rack I built using simple pre-made shelving from Home Depot:



Right now some of the brackets are visible. I may paint them to match the wall color at least, so they're not as obvious.

Here's another look from farther back that shows how it looks next to the fireplace. Overall I'm very pleased with how it turned out.



Phase 2 will be to move a gas line that goes right down the wall where the left speaker is and then switch to in-wall speakers around the TV.

Phase 3 will then be to move the components to a closet and run all cables through the attic/wall. It may end up happening the same time as phase 2, but not for a while yet.

Very nice Carl. If you're ever out in the Bay Area looking to pick up a little work, let's talk I was proud with my accomplishment of putting the LG on a media console, hiding the ambient light, and tying up all of the cables into a neat little bundle, labeled of course, and making them almost invisible. However, you should see the koi pond I built !

So i received my 55" LD630 this week. It was a replacement for a 50" PK550 that i had a lot of trouble with (initial panel had poor screen uniformity, replacement had other issues, there was no more replacement stock in the near future so i was offered the 55" LD630 as a replacement).

The 55" LD 630 has screen uniformity issues as well. It seems i have uneven backlighting that causes vertical streaks. It's very subtle and not really a concern when watching multi coloured/patterened images, but when i watch hockey or soccer (which along with movies make up my viewing habits) where the background is a uniform colour the vertical streaks are visible when ever there is panning across the screen (left to right....so following the action of the play). It's subtle, but annoying.

There is also a flash point near the top of the screen. It's very subtle and only can be seen when the screen is mostly black (it's basically a circular spot of hazy grey). I would consider this more of a minor problem, but coupled with the vertical streaks from the uneven backlight i would say i'm not 100% satisfied with the TV. I should also mention that while watching a HD DVD the other day, the movies menu screen has the selection normally highlighted a SOLID red, but this TV displays the solid red as flashing constantly.

My question is for any members who've had their panels replaced because of uneven back lighting.....were the replacement panels better? I've already pushed LG by getting this replacement set (which cost more than my original TV) and i know if i push them for a replacement panel i suspect they will give me a bit of a hard time. I don't mind fighting them on this if the replacement panel will fix the issues, but i'm not sure i have the endurance to deal with them if the results will still be the same.

I am shocked at the quality control at LG. Their TVs all seem to have issues (or perhaps i'm unlucky or have unrealistic expectations for a TV in this price range?)

I bought a 47ld520 a few weeks ago and just wanted to give a general thanks to the heavyweights in this thread. Reading through it helped me make my decision, and the calibration settings have been great starting points for my own tweaking, especially csamos' since he has the same model.

To add a bit to the recent discussion about yellow whites, I entered in csamos' settings and agree that the whites seemed a bit yellow, especially brighter whites. I downloaded the AVS 709 disc and tried some of the basic patterns to help dial in my panel a bit better. I needed brightness at 52 to satisfy the black clipping test. But more relevant to the topic, the white clipping test showed that the brightest blinking bars (247-250, in this case) clearly had a red tint to them. It was very obvious and not just a matter of me being used to cooler whites or something. To remedy that, I changed the IRE 100 settings by dropping red from 13 down to 5. That eliminated the red veil from the brightest bars and, in regular tv viewing, made a noticeable change for the better with whites. I made some other tweaks based on the AVS patterns, but that IRE 100 tweak was the big one.

Welcome and congrats on your purchase!

I would really love to get my colorimeter on your tv to measure what it is doing compared to mine. Do you have an S-IPS panel? What backlight setting are you using?

I hope to go through a number of tests tonight and post some findings.

I need to find someone else in Austin with a 47LD520!

I have the 47LD520 as well. I'm not sure what you mean by lowering the IRE 100 settings on the red from 13 to 5. Are you referring to ALL of the IRE settings for red (100, 90, 80, etc) or are you referring to the CMS red and red tint? My CMS red is -10 and the tint is -5. The IRE red settings range from -4 to 1 depending on the IRE setting.

I think he means merely lowering red from 13 to 5 at IRE 100 only to adjust the white balance.

csamos - I really like what you've done there. It's very unobtrusive tucked away in the alcove like that, and will be even more so when you finish it up.


You better get on this pretty quick - that austin attic is going to be uninhabitable very soon

Nice work.

Thanks! It really will be very nice when it's totally done. But for now it opens the room up a lot compared to when my big 64" Pioneer was there.



Ha! You'll have to fight my best friend for it. He's been threatening that for years. I really have an awesome attic, too. There's enough room up there for several more rooms.

More confirmation of the differences between sets. On my 47LD520, with csamos settings the white clip blinking bars are fine.

Curious - could you also see the red tint in the grayscale ramps?

That's sort of what I thought but when I looked at my settings, they were polar opposites. Did you post these settings? I don't remember where I put them because I don't think I've tried them on my 520. Would you mind pm'ing them to me or just zip up what you have and post? muchas gracias

Sorry if this has been discussed before but I am unable to search the forum with that function currently shut down. The LG site was no help.
My problem is with the Toslink Digital audio output. I am not getting any output while on OTA viewing. I know my connections, amp, and speakers are OK since I can get audio when using my DVD as a source. I don't see much in the audio menu selection to help. I did have to figure out that turning off the internal is the only way to get any audio out of the optical output at all. Didn't see that in the manual.

I was very disappointed to see that no analog audio outputs are available on the LG 42LD550. I am an old school guy. I had to go out and buy something to receive the optical PCM signals from the LG even though I have a perfectly fine stereo system sitting nearby. I purchased a Vizio VSB200 sound bar. Sounds OK for the $98 I spent and I really like that it has a sub woofer output. I put that to use.

Fred

Thanks. I'll make sure I don't lose them this time. I'll set them up and run them as my OTA setting.

Thanks for the quick response Phase700B. I just checked both of these settings and they ARE set to English. Still no digital audio out with OTA source. So are you saying then that you DO have digital audio output with OTA source?

I just tested the audio using another source - Netflix Netcast. This DOES give me audio on the Toslink digital output.

No, you're not confused, I'm just not being very clear. Been a very long weekend with bad karma I just realized that they are in fact HDMI which won't look right for OTA input.

I spent some time this evening doing some more analysis and calibration work on my 47LD520. I realized that my Sony blu-ray player actually had brightness up a few notches, which accounted for my initial low brightness setting of 40. I made sure everything on my blu-ray player was zeroed out before doing anything this time.

I once again left my backlight set to 25. I just can't stand it any higher than that. The blue glow of the backlight is so painfully obvious to my CRT-trained eyes.

Here are my newest settings. The main things that changed were brightness, color, and some of the white balance and CMS settings. This time I upped color a tad and then used CMS settings to fine tune things a bit from there.

I've attached the resulting graphs these settings generated on my TV. All shades of grey (including white) all look perfect to me with no red or blue tint at all, just as the white balance graph shows. It's interesting that my white balance settings require so much red to be added from 50 IRE on up.

I've done a little bit of content viewing, and so far it looks very nice. The Fellowship of the Ring is on DirecTV right now, and it looks so good I can't turn it off.

Leaving all settings like this, I ran 2 more full sweeps with the backlight set to 0 and then set to 50. There were some slight changes in the various graphs compared to my backlight 25. I'll generate some graphs and such tomorrow and post the results. I'm too tired to continue anymore tonight.

nice setup carl! why didn't you put the tv above the fireplace though...seems like it would be less crowded. what kind of speakers and receiver do you have? turned out great.

Thanks!

Above the fireplace would be just about the worst place for the TV in my room. My couch is parallel to the TV where it is now, so I sit head-on with its center just slightly above eye-level (I opted to make the top of the TV match the mantle for aesthetics), and the surround speakers are placed accordingly. If I had it above the fireplace, it would be way too high for one, and I would have to rotate my body or head 45 degrees to see it. Since I watch my TV a lot, I want it in the best position for watching.

I use a Pioneer VSX-920-K receiver, Paradigm speakers for the front 3 channels, and Emotiva in-ceiling speakers for the surrounds.

Yeah, for sure. I found your settings on my TV likewise don't work at all either.

Hmm, maybe I'll put an ad in craig's list for free or very cheap calibrations of 520 and 550 models so I can build up a good sample set of calibration variations. That would be pretty interesting actually.

Our TV is just barely a month old and we are new to big screen TV's. We bought this TV at Costco. I contacted LG over the weekend with a problem we noticed. Here is what I wrote:

We have noticed that we get occasional flashes of colors in various spots on the screen when we are watching TV. We get green colors, red colors, and so on. They just sort of flash quickly and then go away. Just happening occasionally.

The TV is only hooked up to a DirecTV DVR receiver. We don't own a DVD player. I did all LG requested us to do including a "hard reset". We still see the color flashes. I would say they happen about once or twice an hour.
LG said we would need a service center to look at but we're still in the 90 day return policy at Costco. We do love this TV except for that.

So, is this a easy repair? Should we even try to repair or just return to Costco? You folks are pro's about these so us very senior couple will reply on your professional help.
Feel free to reply here or PM us. Thanks so much for your kindness
