That is correct, i noticed that fiddling with the setting ( ie going up and down is what causes a shift that doesn't go away) So after u have calibrated, write down your settings, completely reset the expert settings, and input them correctly again. At least on my european set it makes all the difference.

I've been trying the last two weeks to calibrate a 36 or 40ftL picture, but I kept getting a slight yellowish tint on IRE 35 that translates to a yellow glow on some flesh tones. I kept running out of RGB adjustment points when I get to IRE 35. I've tried different 100% luminance targets only to find a problem at a IRE 30 or IRE 40 instead. I must have calibrated Expert 1 at a good probe placement, but currently unable to replicate. I did not get low Delta E values across the board, but the picture quality was great. Maybe I'll just keep the same Expert 1 setting and transfer them to Expert 2 and up the contrast and brightness. Have anyone tried that and find the picture quality acceptable or similar?

At the moment I use the "Standard" picture mode for daytime viewing, but I don't want to switch picture settings everytime I turn on the tv to get a good picture. Would like to have a good "middle" setting for both day and night viewing and not play around with picture all the time. Thanks

Waauw, a yellow shift ??? That's a new first ! This set is capable of pretty much anything !

Ok people, i don't know who here is familiar with this set's internal colour wash. I think there is something wrong with it on my set. The white squares never move, only the colored squares move, so if i leave it one for a few hour, the white squares are in the sam place all the time... Is this normal ? If not, can somenone direct me to a good colorwash disc ?

any help is welcome, greetings

It should slowly shift pixel by pixel. It's not really noticeable unless you are looking for it.

My setup includes: LG 50PK550, Logitech Z-5500, MacBook Pro, PS3

I'm planning to connect my PS3 and MacBook to the PK550 via HDMI, and I wonder if the audio would get passed down to my Z-5500 via Toslink as if the Z-5500 was connected to the PS3 / MacBook directly. My PS3 hasn't arrived yet. I've been connecting my MacBook to the PK550 via Mini DisplayPort-to-VGA, and to the Z-5500 via Mini Toslink-to-Toslink

The PK550 buzzes slightly, audible at my seating position (up to 8 ft.) if you listen carefully. It's kinda like old CRT TVs, I could always tell if they were on/off. But my family doesn't seem to notice it.

Well, it's official, ownership flipped one year, so here's a little post mini review:

I still like the set a lot, and when watching BDs, I can still get those "wow" moments on the video quality. I mostly game on the system (using PS3) and have no problems with lag. It is detectable by me, but it is very slight and I have no problems competing. Speaking of gaming real quick, I can not recommend this enough, check out the Aura Pro Bass Shaker. I have the audio out on my headsets running to an external amp to drive the shaker, and man-o-man is it awesome to game that way. You can really feel all the explosions, and gun fire, and even in GT5 for some of the tracks, you can feel the grooves in the track.

Back to TV: Since getting this set I've been hooked on BD. I have a large DVD collection (300+) and around 50 BDs now. The colors look fantastic, as well as detail, and runs silky smooth. I still get some IR, but it goes away quickly. It also seems dependent on the color as Red images retain more often. Screen looks very uniform when showing an all white image. BUT, there is one thing that annoys me some, and that is the Black Level. In a dark room there is no doubt where the set is. I do use a 6500k light behind the set which does help some, but the black still appears more grey than black. It pains me at times when you can be watching a bright scene from a movie, or game and it looks fantastic, but when it jumps to a dark scene, it appears grey. I've tried a bunch of different settings and a cali disc, but the black still is not dark enough to me. I may hold out until next year, or hopefully get a colorimeter by summer to do a proper calibration. All in all though, I'm still happy with it.

Mmmh, i don't know, i see all the coloured squares shift, but NOT the white ones, i was wondering if someone could confirm the white squares should be frozen...

grtz

All squares in the color wash should shift.
post #5019 of 5211
I also have had this TV for almost one year and I still have those "WOW" moments too, especially with Blu-Ray. One questions I have is can anyone discern any picture differences with Film Mode turned on or off? I can't see any difference between on and off and was wondering if my Film Mode is faulty? I was assuming that turning it on would introduce the "Soap Opera Effect" but I can't see what it does to the picture, if anything.

I can tell the picture is very smooth when watching Blu-Ray at 24p, as would be expected, but does Film Mode do anything when watching normal TV?

I really don't see any difference. I know that it is for interlaced images to smooth out as progressive scan, but I've switched back and forth on some channels with it, and don't see the difference. It may be dependent on the source material. For the most part I just ignore it as I mostly game or watch Blu-rays, and they are not affected by the Film Mode (both are set as 1080p).

two weeks in and the buzzing has started when whites are on screen. Blast.

check the screws on the sides of the tv. maybe need tightened or maybe they are too tight, others have fixed the buzzing issue this way.
start with quarter turns, it will still buzz but can be tamed a bit

I figured it may have something to do with static electricity, so I put my finger on the screw on the back of the upper right of the television, and now it's stopped. RANDOM.

If it happens again, I may take a metal clothes line and connect it to something else metallic to better ground the body of the television.

I get this same buzzing when doing the white wash, other than that I don't notice it though.
post #5025 of 5211
yes ive been with this tv for over a year the buzzing on this tv is coming from back panel or bezel is a easy fix i fix mine, just work around and listen close from where is coming from and loose or tight the screw,lg replace the coil boards and nothing that was not the problem, the problem was the back cover and bezel i put a plastic spacer on one of the screw and problem resolve.
post #5026 of 5211
Is there any way to check the model number through the menu or service menu? I'm afraid I have been ripped off through a used sale through craigslist. I feel ashamed to admit, but I think I was sold a PJ550 vs PK550.

If there is a quick way to check which model I have, I would really appreciate it!
post #5027 of 5211
First why do you think you have a PJ550 instead of the PK550??

Second - there's an easy way to find out if you have a PK550 or a PJ550. Look at the back of the set where all of the A/V inputs are. The PK550 will have 2 HDMI inputs whereas the PJ550 will only have 1 HDMI input.

1) Because the box is the PJ550 box, and the labels are changed by marking over the "J" to a "K". I asked the owner about this today, and he said the PK550 box was in bad shape so he used a leftover PJ box.

2) I quickly did some research, and it seems like the 50PJ & 50PK both have three HDMI inputs; 2 in the back 1 in the side
post #5029 of 5211
that's odd...I just downloaded the manual and it shows a pic of the A/V Inputs and it shows only 1 HDMI on the back and 1 on the side panel for the PJ550. The PK550 has 2 HDMI on the back and 1 on the side.

Maybe the canadian version is different:

post #5031 of 5211
You're right...it does have 2 HDMI inputs on the rear. Look at page 36 in the manual. It looks like the remote control is slightly different for the PJ550 and PK550 with the PK550 having an On/Off button for the remote control backlighting. That may be one way to tell.

Unfortunately there is no backlight button I want to be 100% sure before I call the guy again though, is there any way through the menu and/or service menu?

Isn't the pj series 720p? If so, just feed it a 1080p sig and hit the info button and that will show the resolution. Ill check the pj series soon for its resolution (the joys of being at work )

If it is a 1080p tv then try checking the back labels or there may be vents on the back where u can see the model or something descriptive.

EDIT:
I just googled the pj550 and its listed as a 720p tv so if you have any 1080p sources (bluray) and hit the info button and if it shows 720p or 1080i, then its probably a pj series tv.
If the guy sold you a different tv then what you were told, then us avs'ers need to go see this guy and throw him a beaten lol

Thanks for the help. If you have a PJ550 can you please confirm that a 1080p source does indeed show up as a lower resolution in the info screen? As I'm at work, I can't check what I see in the info screen.

Thanks

I had a PJ550 and exchanged it for a PK250 (same as the PK550). Both will display the incoming signal when you push info. Both accept 720P60 1080P24, 1080P30, 1080P60. The only real way to tell is to look at the model number on it.

I read the pj550 was a 720p model, no? That's why I said to feed the tv a 1080p signal cause if its a pj it will max at 1080i. I have a pk550 but every other lg I've looked at in the past has the model, build date, and build location (mexico for most pk550's) located on the back sticker.

ps. Endiz, after re-reading my previous post, I wasn't trying to make lite of your situation with that last comment

This uniformity on mine seems to be getting worse. The repair place wants to try different circuit boards but I'm thinking of returning the entire unit and possibly going for a 3d plasma set...I'm torn here..but I just can't stand the dirty screen effect on my brand new LG PK540. Off the wall mount it comes and back to Costco.

No, didn't read any aggresive tone, don't worry I pushed a 1080p signal through my PCs HDMI out, and in the info screen it says "1080p\\60". I'm still not convinced as the PJ550 does accept 1080p signals, but down converts them to 720p. I will ask the folks on the PJ550 thread.

No, if you send the TV a 1080P signal, it will say you are sending it a 1080P signal. It's not magical and will not convert a 1080P signal to 1080i and then to 768P for display. I don't know where you got that idea, but hitting info on both displays will show you the same information.

You can't fix the bad MLL with calibration.

Potituning is the way to go. This way you can get the best blacks right after the 9G-KUROs if you are lucky.
