Panasonic VT20 Owners Thread

My honest opinion is you guys are being over conscious.
I don't get where satan got the ideas of breaking-in or its usefulness.
All you have to know is the concept behind phospor aging, image retention and burn-in and act responsibly for the first 100-200 hrs.
When phospor ages, it looses brightness. The half life of the recent panels is around 30 years, meaning after 30 years, the panel will be half bright as what it was when it was delevered.
Now, this aging process is not lenear. The phospors age exponentially for the first 100-200 hours. Which means the panels will be 95% bright after first 200 hours and settles around 92-93% in the first year after which the ageing will be very very gradual and not noticiable. During this first hours, if a part of the screen is used much more than others, it will age faster and show up as dimmer. (Eg: if you are viewing a channel with bright logo with max brightness that part ages much faster. Similarly, if you are viewing content with black bars on the top and bottom, those areas will age much slower as black does not exite the phospors atall)
If a TV is used this way.. At the end of 100 hours, the panel will show the part with black bars brighter (since phospor there is young) and the part with the logo dimmer (you can see the image of the logo in pure white or pure black screen or if you go close to the TV looking for it).
The way to avoid this is to use moderate settings <50% so that the brightest and the darkest parts of the screen are not far apart in brightness. YOU SHOUD AVOID BLACK BAR CONTENT COMPLETELY.
The break in slides are for ensuring that the phospors everywhere in the screen age similarly by displaying same colour content and excersising the pixels frequently. Nothing more than that. This can be archieved by putting the TV in 'TV' mode with black and white dots. It excersises and ages the phospor uniformly throughout the screen.
Not watching the TV atall for breaking it is comical. I have been using plasma TVs for quite sometime now and I know what Iam talking. My samsung plasma is 2 years old with no signs or retention. It is more susceptable to retention than the panasonics and I have not done any break-in and stuff to it.
Adding to that, you are going to see the temporary IR NO MATTER WHAT for the first few days. This will go away in no time. It was present in yout CRT TV also. Just that there were no forums asking you to go look for it.
Partial knowledge is dangerous. Dont do something you dont know why you are doing. I will stop here.

Just got mine setup. Got it from Unilet.
Following above methods i got the following as usage and count.
Usage count
20:14 16
Basically usage hours is 20hours and 14 minutes and switched on counter as 16.
Is this a display piece and should i be worried? Should i return this and get another one?
Eagerly awaiting for your responses and suggestions.

Mine was 00000:48 5
I switched on 3 times and used for 30 mins before I checked. You get the idea.
when i was in class 6th my English teacher used say "If you dont clear your doubts, you carry them to your graves" ... So don worry abt irritations .. jus go ahead and ask, respond, react, comment, analyze.. cooly and humbly 
I landed at 3 pm and on the way home got a call from the Chroma delivery guy that they were on way to my place to deliver the VT20, couldnt believe they were so eager when i had mentioned time of 8 pm onwards...anyways decided to stay at home and take the delivery which I did:yahoo:.
The box is sealed and is alright from all sides no signs of damage, havent opened it yet waiting for the panny guy as i stay alone and would be needing help to unpack and set it up.
The delivery process was as under:
a. TV Set- month of import - Feb 2011 (Surprisingly the MRP mentioned on the box is Rs. 1,99,000/-)
b. HDMI keyboard box (Came packed in a small logitech carton...details are of Logitech Honk Kong sending it to Chroma India, couldnt understand as to why they would courier 1 keyboard from Hong Kong to india, MRP mentioned is 1295/- )
c. A Tata Sky HD plus scratch card. Delivery guy has told me to SCRATCH the card and call the Tata sky guys who will come with the STB ....time for my SD DISH TV to retire...
d. The other scratch card (part of the offer) was not provided hence i will have to call up Croma. During purchase they didnt have stock hence told me that they will be sending it with the TV. Any idea what kind of products are on offer for people who have already scratched ?
I am gonna be using the below mentioned process for break in. I would request Blasto, Satan, Amol & other forum members to pls correct and guide me in case i am not doing anything the correct way.
1. Use the below mentioned settings provided by KITTU to check whether the TV is working properly when the installation guy is here:
Mode: Professional1
Contrast 36
Brightness: 0
Colour: 30
Sharpness: 0
Vivid colours Off
Eco-format Off
P-NR Off
Intelligent Frame Creation On/Off (doesnt matter)
16:9 overscan Off
R-gain +1
G-gain -2
B-gain +4
R-cutoff 0
G-cutoff 0
B-cutoff +2
2. Use the below mentioned settings by D-NICE for running in the 120 images i have downloaded which i am gonna run for 5/6 hours every day and similarly more on weekends when i am home to complete the 100 hours break in via the USB pen drive
Picture:
Picture Mode: Photo
Contrast: 100
Brightness: 50
Color: 75
Tint: 0
Sharpness: 50
Color Temp: Cool 2
C.A.T.S: Off
Video NR: Off
Blur Reduction: Off
Slideshow Settings
Display Interval: Slow
3. Settings provided by Blasto: Removing the Green/Yellow cast issue post completion of 100 hours.
4. Reference settings provided by D-NICE post completion of 200 hours for HD movies
I will not be watching TV during this break in period so that the process is completed without any issues. As mentioned in earlier post by Satan, ask as many questions as required.....better be safe then sorry.....
Request all existing VT20 / forum owners to be patient with me, not get irritated by my post and please correct / guide me wherever required.
Looking forward for your support & cooperation...
Latest news guys,
Panasonic 50vt30 is going to be launched in india at 1.4lac with 2 glass free smetime during next month or december. competing directly with sony 46hx925. competitive price is expected to be around 1.25k.:licklips:
Only thing that vt30 differs from vt20 is single glass design and thx in 3d mode, auto calibration. No additional benefits in 2d pq compared to vt20. No wonder vt20 prices are crashing down

hyeah:
sure enough but this bangkok guy has an estimate of approximate price. Only time will tell though. But vt20 launched in india at 1.9 lac. Sources say vt30 is launched worldwide at much lesser price point than vt20. so reasonable enough that vt30 launch price in india will be less than that of vt20. i think i can accept this logic
Firstly, no one here said breaking in was compulsory, not even me. Secondly, I understand that you are eager to help everyone here but, you should take the time to carefully read and understand the other posts. In fact my very first post in this thread gives people the option to choose between running slides or watching regular content on lower settings.
Breaking in isn't an exact science. AV is a very subjective matter and about personal choice. Different people choose to do things differently.
Breaking in a plasma using slides is a very old methodology that plasma owners around the world have used for a very long time. If you took the time to look outside this forum, even for 10 minutes, you would realize how many people use slides to break in their TVs.
Is it mandatory? Of course not. There are lots of people that prefer to watch content on lower settings until they have completed their first 200 hours.
Aside from aging the panel uniformly, the other advantage to using slides is to simply speed up the process of completing the first 200 hours. Most people hate having to nurse their TV's by zooming and stretching content just to make sure that they don't cause any damage. Besides, the picture looks terrible when you have to zoom it in and that's not what I want to watch.
There is a reason that the pro's and ISFccc calibrators recommend running slides during the first 200 hours. You should research that before you try to force your opinion on to everyone and accuse people of being ignorant, unless of course you know something about breaking in that some of the best certified professionals in the business don't.
My 200 hours are almost up (mostly running slides when I'm not at home) and I'm ready to start enjoying this TV without having to zoom in / out. Thank god for that... or should I be thanking D-Nice?

You don't really need to do that. Get the PS3 Media Server (don't worry, you don't need a PS3 for it). It has TSMuxer built-in and will stream MKVs to your TV on the fly. Works like a charm. I've posted a link to it a few pages before this one.
I did not reply to your comment if you see check my posts properly. It was a reply to someone who would not turn on the TV to watch actual contents and wants to run slides for all the time.
That is exactly what Iam saying. It is a very old methodology still being done in the new era of plasmas. Plasmas used to have all the bad burn-ins in the world like 10 years ago. Those required extensive breakin procedure. The half life was 7 years at maz to start with.
Put this in your first post. A lot of people who are in this thread do that stating your first post.
Agreed, But for most people, watching "some" content is better than watching "slides". All Iam saying is dont run the slides ALONE for 200 hours. Accelerating the uniform ageing process through any method is accepted when you are NOT viewing content.
And would that reason be?
I suppose you did the research already. Can you post it for the benefit of others? What is the advantage of using slides? How is it more useful than say, a TV static I mentioned?

hello!
dont become paranoid about ir & burn in.
98% of plasma buyers who dont even know the term break in but can spot IR will never be affected. if u use ur common sense and dont abuse it for the first 100hrs. i am sure u dont have to worry. the below from panasonic..
4. What is the "break-in" period and what should I do during the break-in period to minimize any risk of image retention?
When your plasma TV is initially installed, the first 100 hours of use is known as the "break-in period." During this time, to minimize any risk of image retention, you should:
Make sure the plasma TV is in a viewing mode (aspect ratio) that completely fills the screen. The panel is shipped in this condition, in what is called the "Just" mode.
Turn down the Picture setting (in the Picture menu) to +0.
Briefly engage the 4:3 mode and confirm the side bars are set to "Mid", or "Bright". This can be adjusted in the Set Up menu.
Always return the display mode that fills the screen (such as Just, Zoom, Full, or H-FILL).
Try not to view channels with stationary backgrounds or logos for extended periods of time.
Avoid extended display of static images (video games, computer images, DVD title screens, etc.).
5. I've heard that plasma TVs can "burn-in" over time. What is "burn-in" exactly, and is it really a concern?
"Burn-in," or image retention, is an uneven aging of the phosphors in a display device, can occur on any display that uses phosphors to generate an image, including tube TVs, projection TVs that use CRTs, and plasma TVs. Such uneven aging happens when bright, static images are left onscreen for an extended period of time, which can leave a visible "shadow" effect.
Improvements in panel service life to over 60,000 hours have minimized the risk of image retention. In addition, screen savers, pixel shifting, and brightness level adjustments can dramatically reduce any chance of image retention. Use common sense when it comes to your plasma TV; don't pause video games or watch TV stations with station logos onscreen for long periods of time, and use one of the many display calibration DVDs available today for properly setting brightness and contrast.
The rule of thumb: if you don't worry about your traditional tube TV, you don't have to worry about a Panasonic plasma TV.

One more question to Gurus,
What If I buy old stock, say manufactured about 18months back but never used in between (in the case of Croma selling huge discounted price, In fact, I am planning to get once, hence this question), cause any burn-in/IR or any special care need to be taken care as the Plasma/Phosphors settled for long time without activation?
Am I taking too much risk going for old stock (I agree huge discount means 'risk' too).

The production of this TV stopped in OCT 10. Most of us have bought the same. Any one got newer manufatured dates please deffer this post.
IR can cause if you are using high settings for first view weeks of viewing. Thanks to our frikking DTH providers and channel logos.
But as the TV gets older the IR is no more a problem , as PR gets more into trouble coz of your madness about this IR and stuff.
Enjoy your TV.
Had confirmed a 50VT20 from Haneef - Unilet.. as in Sudhir's case he called up to inform me before shipping that the remaining 2 pieces that he has has run around 36 hours each... i have to decide to either scrap the deal or go ahead with it.. waiting for your inputs..

i havent noticed any, but then i haven't looked for it either.
my motto is dont particularly try to watchout for any defects, u have already done the research, demoed the tv. so just watch it. if something is bad it will show itself, but if u are going to examine evrything critically i am sure u r going to pick up something in some channel or disc in some scene or other.
i have a 32 panasonic LCD in my office and it clearly has motion trails, but if u let ur mind do its job, 90% of the time u will stop noticing it unless there is
too much of it.
the human brain is wonderfully efficient that it can filter so many annoying things out
