For example: Vivid, THX, Standard, Custom, ISF Day, ISF Night.

The reason I ask is because when I had my DLP calibrated in the past, the Dynamic picture menu was the setting I had to use for the ISF calibration. In other words that out of the box picture options where no longer factory because they were changed by the calibration. I was wondering if the newer sets allowed calibrations without disturbing the out of the box user settings.

The VT25 is calibrated by picture mode. ISF modes are added and calibrated, and the other modes can be calibrated as well although there's no point aside from the THX mode. 3D mode can also be calibrated with ISF mode over-layed. The ISF, 3D and THX modes are universal across all inputs, but you still have custom and other modes which you can set for individual inputs, although they are not calibrated.

He calibrated within the Custom Mode in the Service Menu for the Greyscale in Warm 2 which he either copied over to THX OR He may have told me that the THX mode USES the "Custom Mode" Grey Scale. He was somewhat adamant that that THX mode was more accurate to begin with than any mode and really was even more advantageous as a single mode than having the Day/Night ISFccc mode which apparently CANNOT utilize the THX mode if that makes any sense.

No such thing as Custom mode grayscale. THX uses what ever color temp the calibrator chooses to calibrate via the SM (Cool, Normal or Warm). The ISF modes can do the same thing or can use a completely different color temp compared to what is done in the SM.

When I told her she said well it's your money waste it any way that you want.
She insisted that she would not discern any differences at all.

I am more than happy to report that when we watched some TV later in the evening her very first response was an empathic WOW !! Coming from this woman that is the highest praise anyone could ever give IMHO.

This morning we were watching the news and she kept on commenting about how good everything looked. I now have a very different view of her "optical tastes". Unfortunately I am still working on her audio senses but am afraid that after many years this is still a losing battle. Getting a new set of speakers may take a little more time.

Thank you D-Nice for a job well done!!

It was my pleasure. Happy pictures

Last week I had my 50VT25 calibrated by Gregg Loewen. Gregg did a superb job, he calibrated 3D in Cinema mode, I already had firmware 3.5 installed. What a difference compared to my previous JC settings. Avatar now has the impact I remember seeing in the theater, colors are incredible. Gregg also calibrated THX mode which is was impressive to me when I first purchased my VT25 but now it is a true reference mode for night viewing. He used Custom for day but my living room is not very bright during the day and movie watching takes place with all shades closed. All the way through the calibration Gregg explained what was happening. Very happy with my VT25 and kudos to Gregg Loewen, you did a terrific job!

Could you share with us your 3D Cinema mode user settings after Gregg calabrated your 50VT25 with the 3.5 firmware already installed?

Good afternoon
I have a new 54VT25 I'm using a Harmony one remote and an Onkyo 3008.
When I'm watching a 3-D disk the volume control on the Harmony doesn't work
I think I had read something on here about that and I was wondering if there is a fix?
post #9219 of 10650
hi all
Just fired up my new 55vt25 after running the break-in slides for a little over 100 hours. loving the improvement from our bravia. going to look into getting it professionally calibrated

anyone know anyone in the buffalo, ny area they would recommend?

The problem is due to the IR signal blasted to the glasses by the TV, impacts almost any IR remote signal. I downloaded an iPhone/iPad app (Oremote) that uses wi-fi to circumvent this problem. I don't know any other way around it.

Thank you for the quick response
I guess I'll just have to get up off my lazy butt and turn the volume up/down

It's not too difficult to track down the pathway that the IR emissions from the VT25 are taking to find the IR sensor that's being affected. In your case that would be the Onkyo AVR. There are 2 sets of 3 IR emitters on the lower bezel of the VT25. Any reflective surface, including you and your glasses, can be the source of the signal. You could even try blocking one set of IR emitters on the VT25 and see if that fixes it. Needless to say, that could also impact the glasses' function. But usually it will be some reflective surface causing the problem or even a direct pathway from the bottom bezel to the AVR sensor.

Curious why didn't he calibrate the ISFccc modes for day and night and leave the other modes as is? That way there would be no change to the original factory modes, just the addition of the two additional ISFccc Day/Night modes. I assume this can be done if I understand posts 9217 and 9219 above correctly.

Thanks for reposting your report in the owner's thread for your display. I've changed the link in the flat panel (Post#2) lists that are linked at the bottom of my post.

That depends on how important an accurate picture is to your cousin. A flat yes or no answer can't be right.

If your cousin wants the very best picture quality his display can produce, and is willing to spend $400 give or take, then he should contact one of the professional calibrators who have owner reviews linked at the bottom of my post.

If your cousin is happy with his display, and doesn't think better accuracy is worth spending more money, then he is good to go right now.

So has anyone been able to get any type of successful resolution for excessive buzzing on VT25s? Mine is annoyingly loud at 8-10 feet, and can even be heard over dialog when the volume is low.

I bought my TV from US Appliance, and apparently they accept no returns :\\ I guess I am at the mercy of Panasonic now, just looking for hints / suggestions on how to get them to actually DO something.

There are many posts in this forum detailing the answer. You'll see there is a fix.

It's like having tinnitus while watching tv. At one point it got so bad that I actually got a headache and had to turn it off. I called and set up an appt with the Geek Squad. The repairman came and tried to convince me that I should return it and get a completely different tv or exchange it for the same one. I opted to exchange it for the same one - only to find out that the BB stores no longer carry them. They are being shipped back to the warehouses, in anticipation of the vt30's. So, I called Geek Squad again. Repair guy says that he can try fixing it, but that he may actually end up making the sound worse, and that if he does try fixing the tv - we could no longer return it and we would be stuck with it. I told him to just to please fix it. He says he has to order a part (I believe he ordered a new power supply) - he thinks this may be the cause. He is scheduled to come out next Saturday to repair it. Our original call to them was two or three weeks ago, and now the past week or so the high-pitched noise/ringing in my ears has diminished - don't get me wrong, it's not completely gone. It can still get pretty loud sometimes, but I was wondering if anyone else experienced this high-pitched noise/tinnitus of the ear and if anyone had this fixed? Thanks for any input.

My set does the same thing. I had one visit from the techs and they heard it and said that it's not as common as the buzzing, but they had heard it before. They knew the silicone goop fix would not fix it but they were required to try it. When I called next day and told them it didn't work, they ordered two PC Boards and said they would be back when the boards arrived. From what I understand, the boards are on back-order. No surprise their!

I also found that the "squeal" as I call it, is somewhat sensitive to temperature. When the room temperature is below 70° F, it doesn't squeal at all, but above 70° it starts and really gets irritating at 73°.

Kinda hoping that the boards don't work - My BB warranty implies I can get a VT30 if they can't fix it

Hello all. I noticed that Bestbuy.com no longer lists the P58VT25. Is this an indication that this tv is starting to be hard to find or is it possible that it will back on their site in the near future? Thanks!

BB stopped bringing in the vt25 (at least the biggest 2) a couple of months ago. There was debate at the time as to why, as it was reported by people (myself included) that BB said the production line was discontinued. Your store may still have some in stock.

I have been an owner for several months. I can't speak to the banding attributed to the processing that occurs in 96Hz mode.

But I would like to say this: Among many other possible causes, banding or posterization CAN occur as a result of compression or improper encoding in the source. Low bit rate compression will introduce it very noticeably, YouTube is a perfect example. And as far as media providers go, the bandwidth per program varies.

Digital video inherently has banding, the only solution is to use enough bits so that the gradations are "smooth" to the viewer. Obviously, compression is throwing some of these bits away. And given gamma, banding is going to be more noticeable at some brightness levels than others...the same value is applied to wider swathe of the gamut at different locations on the curve. You could consider the gamma adjustment to be "controlled banding".

So to discern if banding is introduced by the set you must, first and foremost, be viewing source material that is encoded properly and without extreme compression. My opinion would be that any source more compressed than a studio released BD would not be suitable. Actually, the only source I would use is a gamut pattern of some sort from a calibration BD. Whether or not it exhibits banding on one set vs another is irrelevant unless you know, quite reasonably, that the source contained none.

And if a source was known to contain banding, but the set's processing reduced it, I would be unhappy because the set is adding information to those areas that is not contained in the source.

So it is a possibility that you are see the banding because you now have a set that is more accurate at delivering the information as contained in the source to your eye/brain than many of its competitors.

I have not seen any banding when viewing grey or color ramps from the DVE BD. I have not seen it when viewing digital photos from my computer set at 32bit color, or HD home videos from my Panasonic TM300. But I see it all over the place on DishNetwork programming. Again, I have not compared 60Hz vs 96Hz for 24Hz content.

Just my 2¢.

Sean

Thanks for this nice post. I don't know how to put this in better therms, but do you (or anyone else) know if the xbox 360 and ps3 deliver image quality with color banding?

I find it hard to believe that game developers would be ok with gamers not getting glows from light sources that don't fade out smoothly, or the change in brightness on the walls from a lit area to dark area in a horror game to look so rough, not to mentions the countless gradients on menus and dashboards where you can count the steps of the different shades. But if the consoles are delivering the image like that and I don't notice it in my other 2 Samsung LCDs (where the gradients all look smooth) because they are doing some post processing to fix it, I would stop being so obsessed about this. I still think there's something wrong with my setup if there's not many complaining about this, or maybe that's because not many here play games on it and watch mostly movies where it's harder to notice.

Got my TC-P50VT25 delivered tonight. The delivery guys helped to put the pedestal together and lift it onto my dresser. When they left I noticed this:



I didn't notice it at first because the screen is so dark. It's much more noticeable when the camera's flash is on. I haven't even plugged it in or anything.

Oh well, just thought I'd share. Never happened to me before but now I can sympathize with those who have experienced this. I'll be sure to inspect the replacement TV more carefully next time before the delivery guys leave.

Oops! That is why Chris at Cleveland Plasma insists that you plug it in and turn it on WHEN the delivery guys are there.

Dear All,


I would like to know if anyone knows what is the difference between 7.5 IRE or normal White Balance in my VT Plasma? I notice that one is darker than the other but is here anything else?

Thanks,

Michael

New VT20 owner here. I'm currently running Evangelino's slides in order to apply D-Nice's setting. Do you guys inspect the screen when you run the slides? I seem to see all kinds of little imperfections when I do that and I'm going crazy here! Are screens suppose to be perfectly uniform on all slides or should I wait to watch regular material and judge from there?

Well we don't want you going "crazy", there are already enough members here that have jump over that ledge.

If the slides are using all the pixels then the picture should be pure and consistent from corner to corner. If say every other pixel was used then if you were scaling you would get some interference patterns.

First be sure you are scaling 100%. Go in menu under Aspect control and set it display whole picture, not 95%.

If you could describe what you are seeing a little better I or someone else might make a guess at what is happening.

The most common problems on new screens are dead pixels, either constantly black or white. Another problem is an uneven brightness & color across the screen, bad purity. The latter means that the screen has been damaged in some way, possible being twisted or strained by the frame. Problems like this can only be addressed by a new set.

By the way I don't think that you need to run the slides. Just go ahead an apply his settings and be sure to watch full screen videos only until over about 100 hours. Don't let any static image or portion of the screen, logos, stay on for more than an hour or so until over 100 hours and you will be fine.

hi all
I noticed this the other day but thought that maybe it was just the nickjr channel my son was watching. My wife noted today that it seems to happen on most SD source channels. Especially our news. there is a strip on the very top of the tv with white lines separated by space. Occasionally there is flickering in the colored area between the white. It seems this is a defect in the picture from the broadcast or that the tv is showing. I seem to have fixed it with size 1 or 95% aspect. is this something to worry about for my vt25?
thanks
