Stop............. Kuro time

Still have mine! It's not quite settled into its new home yet :D

Now i've got a bigger place, it seems to look 20 inches smaller. Perhaps I should shave around the base, I hear that adds a few inches.

Who still has their Kuro then ? My friends have been buying TVs recently and I am completely out of date. From a quick skim even now it seems the Kuro has yet to be beaten?

Mine is sadly suffering from the red tinge problem to the point blacks are now showing significant shift towards red and it is in a cupboard as Pioneer advise it is in spec and won't replace the panel under warranty. I might brave the service menu and try and sort it but it is a can of worms once you start changing the factory settings.

The Panasonic VT50 runs it very close it has a sharper picture, better handling of fast pans and in a normal room the black levels look identical. I couldn't buy one as I can see a very annoying flicker some people see with them. Now waiting for OLED sets !
 
Get it calibrated or do it yourself - will most likely sort out your issues

The blacks change over time on the Kuro

I had my brightness on +1 for about 18 months - now I have it on 0.

I can give the charts and results of my calibration - but calibrating a Kuro is so worth the time and money as its like having a new tv

A calibrated Kuro will take some beating - the difference with modern Panasonics - they come near calibrated out of the box so thats why people think they are better - clever
They do have a better greyscale managament systems than the LX range, the same as the KRP range so you can get amazingly low delta levels on the calibration, however mine are all around 1 which is proper anyways :)

My 5090 is easily the best "tv" Ive ever had ("tv" because it doesnt have inbuilt speakers, so its strictly speaking a monitor), I just wish I could have afforded a 60" when I had the money, as mine is appearing smaller by the day :(

It is already IFS calibrated but it can't be calibrated out now as the shift is to great as the other colours get affected when you try and calibrate the red out. It basically needs a firmware update to resolve the issue with the ageing algorithem that is used as the panel ages the problem is Pioneer don't have anyone to do it.

You can clear the issue for a short time by using the service menu to tell it you have replaced the panel and set it back to 0 hour usage (the ageing algorithem then gets reset) but you then have a older panel being driven with incorrect voltages for it's age and then you have to start tweaking service menu settings to get rid of white spots that can appear due to misfires, some owners have spent weeks/months changing settings no one really fully understands trying to resolve the issue.

As I said a can of worms ! I am hoping Pioneer change the stance they have at the moment that as the TV gets older the black performace is expected to degrade but they can't really as they wouldn't have enough spare panels to replace the ones affected, the fault isn't really with the panels anyway as it just allows the set to be reset properly and run for a while before the issue is likely to start again.

Lengthly thread about it on avforums. I will probably have a go at resetting the panel when I have some time. I am still threating Pioneer with legal action so I don't want to change any service menu settings, but this is likely to go nowhere and not really worth it as the TV isn't worth a great deal these days.

For reference the VT50 I saw was IFS calibrated, they have a green tint from the factory but this can easily be calibrated out, very close to a calibrated Kuro.

I don't think anyone knows why some sets are affected more so than others the general theory is the harder the panel was driven the quicker it is affected by the red tint, so ones calibrated in dark rooms last longer than ones done in light rooms. Usage also has an effect most affected are around 4000-5000hours upwards. You should be fine for a long time with a new panel.
 
That is interesting reading

How hard do people push their sets?

I have calibrated it with a contrast of 36. 38 had more pop but it hurt my eyes after longer watching sessions.

It does amaze me when you read the HDTV test reviews of the pannys - every year there is a problem with them - first it was floating blacks, then something else.
I think there still is something with the 50 range as well cant remember.
I dont remember anythign like that reported about the Kuro range.

Some are obviously going to go wrong - this is mass market electronics and they get bloody hot, but my fans have never come on?
 
Mine is still as good as ever, certainly don't see myself upgrading until OLED becomes mainstream and prices drop.
 
Hmm I have started to notice a slight red tinge on my 5090. Only noticeable in a dark room but a bit annoying

Not played with any settings in ages bit is there anything I can tweak without needing a calibration ?

A calibration won't fix it, you need to enter the service menu and reset the panel timer you then need to mess about with several other settings that really no one properly understands ! It is basically not worth it as I spent several days mucking about with it and a month or two later the red tinge is back so I gave up as I just wanted to enjoy watching movies/TV without spending hours tweaking so I bought a Panasonic ZT60 as they were dumping all remaining stock cheap as Panasonic pulled out the plasma TV market.

A big thread on the red tinge problem and instructions to try and resolve if you are feeling brave http://www.avforums.com/threads/pio...acks-part-2-now-open-to-other-models.1719687/
 
Got to laugh at the peeps at start of the thread defending LCD, 6 years later and they are still poor and cannot touch a Kuro.

Anyone with a 9th Gen PDP-LX5090 or PDP-LX6090 or KRP-500A or KRP-600A is very lucky.

lol. Near the beginning of the thread there was a comparison of the same scene on a kuro and an lcd and it was a 'look how much better plasma is than LCD' comparison but the colours on the lcd used were all over the place. I remember it well; Will smith looked like a lobster - no half decent lcd ever looked like that and that's what sparked the discussion. That's why simon said this in post 75 after i posted the same scene displayed ony my sony lcd http://forums.overclockers.co.uk/showpost.php?p=12041288&postcount=75 The original shots are gone though so i guess it reads more like people justifying their LCDs or whatever. Didnt happen like that though.

I wouldn't say that all of them are slowly turning the picture red an annoying issue that could be resolved with a firmware update to bring the panel ageing algorithm back into sync with the panel but Pioneer have no one able to carry out the work.

To keep the blacks black you then need to tweak several settings in the service menu settings every few weeks as the panel ages and some are also taking the rear off the panel and adjusting voltage pots :eek:
 
Still the best TV ever made, better than any POS LCD by a mile.

The fact the last one was late 2008, or early 2009 (AFAIK) means they have got some age on them, but some peeps use only at weekends on rich basts in 2nd homes.

You can get lucky and get a good one but its getting harder since about 12month ago.

To have got one new and used for years must have been bliss.
