BTW, most people buying an 8500 are buying the 64" model so it is not an apples-to-apples when comparing to the 60" 5300 or 6650. Still, even when available months ago, it was ALOT more.

Friend bought an open box from PC Richard last fall and paid $2,000.

Smart move....unless you are super-close to the TV and/or it is a HUGE screen you just don't see any benefit from regular 1080p HD programming. I think the only 4K programming is NetFlix. Sort of like buying an HDTV in the U.S. in 1997.

Price should plummet once Samsung decides on their OLED strategy, in or out.

I've heard that from a few people about looking 3D. Must be the PQ and black levels. Could also be the size; many people seem to have gone from smaller TVs.

Yeah, Cnet has been saying in 4k TV reviews that a good 1080p blu-ray still looks better that the Netflix 4k stream due to compression. Until channels start broadcasting native in 4k (long way from now considering most broadcast is 720p or 1080i) I see no benefit from being an early adopter.


My LG 6650 is set to be delivered on the 20th and can't wait. This is an upgrade from a 2005 50" 1080p Sony Bravia rear projection. Was a great TV but just washed out in dark scenes. Game of Thrones and Walking Dead were hard to watch. Bet I'm in for a good boost in PQ from that.

50" or 60" LG ? Even if the same size as your Bravia, the increase in PQ will be noticeable. And the thinness of the new TV will be greatly appreciated.

The LG is a 60", so getting a good bump in screen size as well.

That's a nice bonus.....though my older 50" 720p had huge bezels that made it close to the same size as the 60" 5300 with thin bezels. Sometimes I wondered if I had gone up 10" in size !!

just follow old fashioned advice full screen movies watching and break in slides for at least 100 hours better be carefull till 200hours and anyhow run through picture wizard few times till plazma cells will settle down Expert settings with warm2 white adjustment is certainity enjoy, wish you luck !

Question about 24p playback on the PB6650:

I keep my devices (PS3, HTPC, laptop, etc) connected to my receiver. The receiver is connected to HDMI 1, which I've labeled as a PC input to nearly eliminate lag and shut off unnecessary post-processing on the TV in "Picture Options" (dynamic contrast, etc. are all non-switchable except for "black level").

During normal use, my devices run at 60hz, which keeps every working fine. However, when I play a blu-ray on the PS3 and the presentation switches to 24p and 24hz on the TV, the post-processing choices in "Picture Options" are now all selectable again. I've kept them all off and set the "Black Level" to high as the signal is full RGB. My only question is what I should do about "Real Cinema". "Real Cinema" is meant to be a way for the TV to correctly display 24p signals, if I'm understanding it correctly. But, when I select info, the TV shows that the signal is 24hz even when Real Cinema is selected off as well as on. I've encountered the same problem with some specific video files off my HTPC which change the TV display inputs refresh rate to 24p.

So, Real Cinema on or off during 24p playback?

my personal choice is to have real cinema off and so I have off 24p playback as black level on 24p or 50hz is on my set much lighter and worse compared to 60hz, if you will carefully compare difference in blacks is really huge at least in my case. Real cinema if you dont care for black level is better to be ON, otherwise if you see yourself no stuttering and issues with motion 60hz is my personal choice advice, I have on Sony BD player turned off 24p playback and I am happy much deeper pictures of Blu Ray movies because of better blacks

Think of black level setting as black level. Black Level set to High gives you lighter blacks. We normally want darker blacks. Set it to LOW.

Actually, the "Black Level" has to match the RGB values the set is receiving. As my input was in PC mode and my HTPC was outputting full RGB 0-255, High is the appropriate setting for Black level. A Low setting would have given me crushed blacks. If my HTPC was outputting limited RGB 16-235, Low would be the appropriate level.

I've since opted to leave "Real Cinema" on in 24p mode (and whenever available). Our PB6600-6900 manuals call real cinema 24p 2:2 pull down, which means that every frame is repeated twice for an effective refresh rate of 48hz in 24p mode. This minimizes screen flicker between frames if the display was actually playing 24p at exactly 24hz. However, searching around I found this forum poster's take on our plasma models at

http://forum.blu-ray.com/showthread.php?p=9651489

"3. LG plasma screens use to be all frame locked at 60Hz with 3:2 pulldown judder when a 2-D 1080p/24 signal was received. However in 2009 LG started making plasma screens that operated at both 48Hz and 60Hz. When film mode was switched on in the LG PS60 and PS80 series 2-D 1080p/24 material used Real Cinema 24p (2:2 pull down) technology at 48Hz. However, LG discontinued the 48Hz feature. Some people see image flicker on flat panel screens at 48Hz because of limitations in the technology. Between 2011-2013 100% of all LG plasma display models including the lower end 768P models operated at both 72Hz and 60Hz (72Hz is the same technology used on the 2006-2008 reference Pioneer plasma screens). The latest LG plasma screens correctly display native 30fps and native 60fps video based material at 60Hz without using any 3:2 pulldown. In addition, when a 2-D 1080p/24 signal is received the 2011-2013 LG plasma screens will display the image on the screen at 72Hz when “Real Cinema 24p (3:3 pull down)” is turned on. The select few LG plasma models that do offer the 3-D feature, all use the active shutter glass technology at full 1080P quality. However, what is disappointing about the LG 3-D plasma models is that none of them offer the 144Hz (72Hz for each eye) mode when a consumer watches a 3-D movie. Currently all LG plasma screens are using 120Hz (60Hz for each eye) with 3:2 pull down when consumers watch a frame packed Blu-ray. The following is the problem with the spec sheets when it comes to the 2014 LG plasma screens. If one looks at all the spec sheets for the 2011-2013 LG plasma screen models they all list the 72Hz “Real Cinema 24p (3:3 pull down)” technology. One example is the 2013 LG 60PH6700 spec sheet which clearly mentions “Real Cinema 24p (3:3 pulldown)”. However in 2014 it appears that LG by mistake has listed all their 2014 plasma models with 48Hz “Real Cinema 24p (2:2 pull down)” technology instead of 72Hz “Real Cinema 24p (3:3 pull down)” technology. For example the 2014 LG 60PB6900 spec sheet clearly only mentions 48Hz “Real Cinema 24p (2:2 pull down)”. Most likely, this is a misprint in all the LG 2014 plasma models since historically 48Hz produces an image flicker. Since the 2011-2013 LG plasma models use flicker free 72Hz technology it would not be logical for the 2014 LG plasma screens to use old 48Hz technology that has flicker issues. Therefore, the theory is that this is just another misprint when it comes to the spec sheets for the 2014 LG plasmas."

So, it seems likely that our Real Cinema is actually 3:3 pull down, playing back 24p content at 72hz. Would appreciate it if any of the AVS experts on this board can confirm that.

Hello I will do finally POT tuning with manipulation assistance of my friend, and without scope, with TV turned Off. What I am certain I will mark original POT position, then I will try to go fully clockwise with Set UP and Set Down, and will go 1h in clocks down from max clockwise position. I expect pixel missfires, if happend so again opening of TV then Set up in the middle , between original postion and max counterclockwise position and I`ll check. If Picture is too grainy Set Down is too maxed.. so little down again I won`t sure get max blacks but I`ll check if no pixel missfires and if its better in 2d , 3d movies in bright and dark scenes and after cold start. Maybe I would be able to do it tomorrow or day after, depends on mines friend free time. Disassembly assembly will be for me tricky , I put TV on table faced down , table will be folded with 2 thick blankets (2layers) to make cushioning anddd backpanel is burried deep inside bezel so some screwdriver is necessary to pull it out after screws are taken out ? I think so. Anyhow gloves are prepared to not cut me and my friend Tv backpanel is sharp and bezel as well. I will put down screws exactly on places how I will take them out to easy know where to put them again it was recommended very helpfull. Any issues of dissasembly assembly warning are welcomed, dust can come easy to set when you are not carefull and so on. Stand shouldn`t be issue to apply in after backcover is put again on tv right ? Stand can be put in when TV is faced down on table and on the edge of table you simple put stand inside TVand apply screws right? Thanks for crossed fingers, even 30-50% improvement of deepest black is maybe too much expected , we`ll see.

pink & green tint white colour & light colours

Hi after long time my pink tint on my tv is much bigger area actually part of area is pink and part is only green tint, there is no clear white Picture on fullscreen white, or there is hugely tinted light grey or sand colour light colours during slides, I can see this issue mostly using PC on TV, with browser and static pictures. On movies I see issue on very white background very minimally and just not bothering. What is your opinion? I think my panel has serious uniformity issue with white and light colours, there is not this issue visible with deep colours. please check attached pictures. I think here in Slovakia is hot summer, can these tints became more visible because of very hot weather? In my room is 27 degrees max. anyhow. That uniformity is really ugly not a slight issue with my previous old plasma with this. I think I have worst panel from 2014 LG plasmas which has this issue, based on what I have seen posted here by other users having similar issues. What I have read after 3 exchanges people were getting similarly pink tinted new panels ... and thats not improvement really. when I checked DSE , dirty screen effect test on YouTube it was like map my screen, but bereable not visible during normal movie watching...

My 60pb6650 started turning on and off on it's own. Anyone else have this issue; maybe an automatic firmware update gone bad? Going to contact LG support in the next day or two since it should still be under warranty. I'm sure that's going to be a blast. I'll keep you guys updated on what happens. I dont have very high expectations though.

I've had my unit turn off and on maybe two or three times randomly. However, there's also some consistent flaw with all LG models pre-webOS that makes them shut off and then turn back on while you're playing certain types of files over DLNA. None of my reboots was an endless reboot-cycle, though, if that's what you mean.

Yeah, it's an endless reboot issue. Does this without any cables plugged in or touching anything. Pretty sure it's done. My wife started the warranty claim with them and their email response was almost comical since they were telling her suggestions like go into the menu and make sure the sleep timer isn't on and such. And how the hell is she supposed to do that when it doesn't even turn on for more than 1 second. She explained all this in her detailed message. Hope the rest of the people we have to deal with aren't knuckle heads. I'll update if I finally get a tech or somebody to come around.

I've noticed something with my 60PB5600. When I sometimes turn on my PS4, at the first screen where it shows the PS4 Logo, it is bright white logo. The background is super black, while this logo is on the screen! Then when it disappears, black level raises up to horrible levels. What would cause this? It is not my receiver nor PS4 settings. It is ashame that the black level is only super black, during this time the logo is showing up.

It most likely that the white is super-white, driving the set's power supply into limiting, thereby also lowering black. To prevent this (these settings are for PS3, I assume that PS4 has similar settings) set:
  • RGB Full Range (HDMI) to Limited
  • Y Pb/Cb Pr/Cr Super-White (HDMI) to Off

Great picture in dark room

Just checking in, I was posting on this forum during my research before buying the PB6650 in the spring. I decided to rent a movie on Vudu last night, the new Mad Max. I started watching it upstairs on my Sharp Aquos LED. When the movie started, I kept messing with the picture settings, but I just wasn't happy with the results. The blacks level were not good, and the colors seemed off. It bothered me to the point that I went downstairs to my 6650, turned on the xbox and downloaded the Vudu app, signed into my account, and started watching Mad Max again. I was kind of shocked at how much better the picture looked. The blacks were way darker and more even, the colors were deeper and richer. I know everyone says Plasmas make a better picture, and I can tell you first hand this was true last night. With a dark room, this plasma is a beast!

Well just an update to my problem of my 60pb6650 turning on and off. The repair company that LG subcontracts finally got somebody out here today and they threw some parts at it (I assume the parts that we were waiting on) and it turns out the whole panel is bad. It will probably be another couple of weeks before we hear anything again. Hope this is just a fluke and not the typical life expectancy of these TVs. Will post back when I see waht happens with it. LG should just send us a new one at this point if this goes on much longer.


Edit: Oh, and I meant to mention that if you have to deal with LG support just be careful. They seemed like they were trying to weasel their way out of honoring warranty claims any way that they could; where it was purchased, if it had any scratches on it, etc. Hell, they even said that the warranty was voided if the tv was wall mounted. WTF! Why does it have mounting holes on the rear if you're not permitted to use them? Anyway, just a heads up.

Hi guys, I have question, which of you have no uniformity issue with white colour and grey colours, I mean on expert settings and warm2 setting (on colder colour setting like Medium it is less visible) ? I mean any green or pink tints in white colours, visible on clean white and grey slides as well on bright and grey movie scenes in problem places. I am wondering I have refused offer of LG to exchange panel because ISF calibration is looking Great except of pink tint fault. If there are most of users having perfect white and grey colour uniformity with no tints, I will have more courage to exchange panel even I will loose Isf calibration. ( I am worry many people reported pink tint issue, that Exchange will be just another panel with pink tint issue and without Isf calibration, and here we go again ) . Mostly pink tint has been reported here by only few people , so it is not issue for most of panels. Is pink and green tint connected with panel voltages? Thanks for sharing info,


p.s. ISF settings are anyhow big praise for changing of panel in panel lottery normal way is to carefully check it before isf calibration is done.... hm

I am wondering I have refused offer of LG to exchange panel because ISF calibration is looking Great except of pink tint fault. If there are most of users having perfect white and grey colour uniformity with no tints, I will have more courage to exchange panel even I will loose Isf calibration. ( I am worry many people reported pink tint issue, that Exchange will be just another panel with pink tint issue and without Isf calibration, and here we go again ) . Mostly pink tint has been reported here by only few people , so it is not issue for most of panels. Is pink and green tint connected with panel voltages? Thanks for sharing info,


p.s. ISF settings are anyhow big praise for changing of panel in panel lottery normal way is to carefully check it before isf calibration is done.... hm
My friend has the PB5600 and it definitely has a pink tint on the right side of the screen. Not sure if the PB 6600 are generally less prone to pink tinting or not.

Thanks for feedback Any more people has pink or other tint issue on white and light grey colours , especially on full white and grey break in pictures ? What I found dynamic colour set upped on medium is removing pink tint but it is looking really ugly. I like to hear from people which has perfect uniform whites and greys as well . I think some panel series of 2014 Lg plasmas has pink-green tint, less or more pronounced
However my plasma 60pb690v(aka 6900 US) is special it is pink tinted in left & right side and green tinted all over other places why to bother to have white colour :P


I think Pink tint on LG plasmas is not mentioned and reported by many users, because it is less visible like it is on Samsungs, and it is visible only occasionally in light colour and white backgounds. However I have seen pink tint reported on 60" - 60pb5600 , 60pb6650 and 60pb6900 as well as european versions, I haven`t heard about this on 50" model.

I have found firmware 04.04.02 for my 60pb690v have you found some similar firmwares for your model and have you installed it already ? Is there any difference from previous version? After ISF calibration it is better to not install any further firmware updates correct? Tks

I have 4.03.03 currently. I did read LG is rolling out a Web OS 2.0 upgrade for 2014 models starting this week but I haven't noticed it wanting to update yet.

Just and update to the warranty claim I submitted over a month ago; support said that the new panel which was needed went to the repair company last week and we should contact them and arrange an appointment (again). Were supposed to come Friday and they flaked on that. Then Monday which is now Wednesday or Thursday (wonder what day it will actually be once Thursday gets here- may be a day the following week). I'm not too optimistic about this new panel actually fixing the damn thing since last time they were here and powered it up after throwing parts at it, it threw a bunch of sparks according to my wife (hooking up the defective panel probably shorted out a bunch of other things like another circuit board or power supply). I know these are first world problems, but I've been without my tv over a month now. It's getting kind of ridiculous now.

My 60" PB6600 died at 14 months of age. I had bought the TV with my AMEX card, which doubles the manufacturer's warranty, so I filed a claim.

Called LG service center, who dispatched their own tech a day or two later (tech is an LG employee). Initial diagnosis was a bad DSP board. The tech didn't have the board on his truck, so LG shipped one to my house the next day. After it arrived, I called the tech, who showed up later that day. Unfortunately, the board didn't fix the problem. Revised diagnosis was a bad panel. There was no charge for the first or second trip.

The tech said it could take 6 weeks or longer to get a replacement panel, as there didn't appear to be any in North America. Fortunately, he called the next morning and said he could get a panel in two weeks. I agreed, so he showed up two weeks later and replaced the panel.

The total charge was $190 (part was covered but not labor). I put it on the AMEX card and was credited the full cost of the repair after filing the appropriate paperwork.

The new panel is much better than the original. The black level is good with no adjustments needed. The original panel's black level was so high, I had to adjust the internal Setup and Set-down pots to get a watchable picture. (I don't know whether those adjustments contributed to the panel's demise, but LG replaced it with no questions asked.)

In conclusion, I was pleased by the service I received from both LG and AMEX.
