LG also has floating blacks, probably worse than Panasonic

Great videos, finally someone who "can make a proof video", so ppl that wasn't so difficult after all?!
Thanks olivluca.

(Now we can wait for the comments like..."its softer", "it's worse", "it's faster" or "better than panny") All in all...we have them all the way, and obviously WILL have them for many years to come, more or less...sad but true.

Well mine doesn't do that at all. And yours didn't until they replaced the panel. I'm guessing you didn't get any results with the EECB then?

my lg pj350, is coming tomorrow. im not gonna be happy if it does this. but im coming from a crappy sharp lcd. i probably can live with it. as long as it doesn't get worse.

:/ could someone with a G20 please please try that test video too ?

Great example......I've been wondering just what "Floating Blacks" looked like since my Panny S1 does not do it.

How about the LG 2010 plasmas then?

No floating blacks on my 2010 LG Plasma, with 500 hundred hours on it.

Keep in mind, the OP is talking about a previous generation European model. Why he is posting about it on several threads, including the Panasonic ones, on a North American Forum, is a bit mystifying.

If it were a standard problem, on the European models, then surely their must be some sites that have threads dedicated to the problem?

Well on a bad day I'd be tempted to say that this should be renamed the "Floating and Rising Blacks Forum" as there seems to be a steady flow of postings on that topic no matter what the nominal model being discussed. It's something people just can't say enough about, it seems.

Well, from these videos this is a lot worse than the floating blacks on my Panny S2.

I recently finished the calibration of my 50 pk550. This was the first machine I calibrated following ISF-rules. So I spend many hours with the screen and next to the calibration signals I played a lot of various test discs just to see how things worked out.
I had nothing happening like described here.

If I see those pictures I think of lousy signals ...... I can hardly believe that the plasma makers (be it LG, Panasonic or Samsung) do this decidedly.
I believe in the "blackest black"stories but I think the "floating blacks" are just made up by people that do not handle their equipment right.

I guess if it is a real problem, and it appears to be for some owners of Panasonic 2010 units, it makes sense to dedicate a thread to it. I just took a look back at the OP's posting history on his problem with his 2009 European LG model. It turns out that he had the panel changed on the unit, because he was noticing a lighter spot on the screen. When he got it back, with the new panel installed is when he started experiencing the "floating blacks" issue that he is now talking about, so it appears to be a problem related to how the repairs were handled, and who knows if the installed a new, or used panel? It appears to be a one of a kind issue, and he would appear to be making too large a projection; "that it happens on LG models, "probably worse than Panasonic", just based on his experience with his one 2009 European unit, after it had gone through transplant surgery.

Here is what he posted back on 4/17/2010

"Hello, I just received my tv sent for repair (an lg 50ps8000, the european version of the ps80 but without ethernet) due to a brighter patch on the screen.

They replaced the panel but I'm not sure they calibrated it properly (difficult to demonstrate without a colorimeter, but the thx preset doesn't seem right compared to what I saw before).

Anyway, I found that the black level raises with only a small amount of white (or any other color). I know that a plasma screen would do that when there's a lot of bright spots, but not with only a small one, and I don't remember seeing it before.
I prepared a small test video here, that's just a black background with a small white square turning on and off.

While it doesn't happen with the video, I also noticed that sometimes the black level doesn't restore itself back to the "normal" level even with no white spots on the screen! (though it resets if I slowly put on the screen a white patch and take it back again).

Is it normal or does it actually point to a badly calibrated panel?"

Thanks for calling me a liar.

I think Panasonic did it to make bright scenes brighter, and dark scenes darker. They just didn't count on rapid switching between the two. The stepdown in brightness levels is obvious; even my wife noticed it with no prompting from me.

95% of content is fine. It's just that extra 5% where it shows up and takes you out of the movie.

I've spent numerous hours playing games and watching movies on my 50PK550, which I calibrated myself with my i1 LT and Color HCFR. I've never once noticed anything like those videos.

Without reading the through the whole link that the OP provided, how do we know that all "image enhancement" features are disabled? Dynamic contrast and ECO modes come to mind. I'm not saying that anyone is wrong, but those are things that need to be addressed, and should've been in the original post.

Since it only happens with the THX settings, then it clearly is not a problem with the panel. It is how the THX software is operating. Your problem is with THX certification, not with the LG unit.

I seem to recall that Panasonic had a problem with their 2009 THX settings, and they later released an update patch to fix it. Have you checked to see if LG has released any update patches, that the service people might have failed to update?

It makes me laugh, someone comes on this forum to educate themselves before making a purchase, and pretty much find they need to compromise with all Plasma makers: Panasonic's blacks can float and rise, LG can float, Samsungs can buzz. Pioneers are nearly gone.

Makes LCD look tempting lol.

unless plasma can get it's act together in the next couple years, I will be going with the best local dimming lcd for my next set.

SED would have solved all these problems

I think the title of this thread needs to be changed, as it reflects only your particular tv and not all of LG plasmas. I have the 50PS80 and mine does not exhibit this behavior whatsoever. Your panel is bad and it is surprising that the lg guy told you a bunch of BS.I do feel bad for your situation. That **** would bug the hell out of me.

+1

LG has had their issues but NEVER with floating blacks. This kind of thread title is what spreads misinformatiion......and there is enough of that on the internet.

OP, reps have been known to sometimes give out wrong information. Sorry that you are having problems with your LG though.

your videos make this look much worse. i barley notice this if ever at all. i have the 42inch pj350. i still like this tv more than any lcd i have seen. & more than most plasma's once set up right this tv has unbelievable color. amazing picture! for $500.00 its the holly grail. as far as im concerned

i will try to post a video! of my unit. i do notice the backlight changing brightness. but its to suttle. i have to strain to see it.

Yours changes because you have dynamic contrast enabled. This thread is misleading as it indicates that floating blacks is a problem with LG plasma sets which is incorrect.
