I keep telling them that it happens when the source is directly connected to the TV, but everytime I am on the phone with them they ask me these questions and its getting annoying now and if they think the brightness change is a feature they are mistaken. How can they call it a "feature" when they are fixing the same exact thing on the VT30's. It makes no sense.

you can use my experiences as part of your argument. i have gotten floating brightness with the following devices hooked up directly to the tv: ps3 fat, ps3 slim, xbox360 fat, wii, bell hd pvr 9241, toshiba hda20, and a toshiba qosmio x500 laptop. i also experienced the "feature" when these devices are hooked up via different receivers: a pioneer vsx1325 and a onkyo txsr605b. i have never seen this issue with these same devices when they are hooked up directly or via the receivers to other tvs: a pioneer pro111fd and a samsung lnt4065f.

panasonic did address my buzzing issue and ticking / cracking issue under warranty. i was very pleased with the service. i have not gone to panasonic about the floating brightness issue. i was hoping a definitive solution would be available before i made contact. i will be calling them when i get the chance. i don't think a fix will be available. will keep everyone posted with my progress.

acetheog: I live in the same general area as you. I am curious, what store did you purchase your VT25 from? I am assuming you did not pick up an extended warranty of any kind. Have you tried phoning the store and speak to a manager about the problem? I have done this in the past and they have exchanged a TV long after the 1 year warranty expired.

Panny Canada will not fix this or even try to. To them it is a feature..... end of story according to them. Try your retailer or extended warranty or something. Sadly I bought my G20 from Audiotronic who just went out of business so my extended warranty is now lost but I was going to look into this had this not happened to me.

But I do wish you better luck sincerely than what has happened for me.

I wasnt suggesting the extended warranty would somehow fix the fluctuating brightness issues that Panasonic says are unfixable. All i was saying is if he held an extended warranty and says the right things, he might have enough leverage to convince the original retailer to exchange his year old TV because he has never been happy with it. The retailer would then sell the set as an open boxed item. I was able to do this a few years ago with a different TV. The retailer might laugh at his face, but it costs nothing to ask.

No problem Mike I understood your point I just meant he might have a recourse under the extended warranty if they didn't know it was a "feature" & perceived it to be a flaw & if they couldn't fix it he might get his set replaced or refunded that way. I was going to attempt this myself but of course lost my warranty so can't proceed that way.

Your way could work as well I was just saying Panny will not do anything about this especially here in Canada so it has to be resolved.....or not through another avenue.

How can Panasonic say that the fluctuation brightness is a "feature" for the VT25 sets, but when it comes to the VT30 sets its a problem they are fixing? This makes noooo sense to me at all.

Has anyone had an issue with vieracast where you can't tell which app window is highlighted? On every other vieracast enabled product I have the borders of the apps light up blue as you scroll around to select them.

They told me it was related to the Energy Star performance thing & it was intended to function that way. I might be off calling it a "feature" but then they don't call it a "flaw" either.

Bottom line is if the set is working as designed according to them then there is nothing to be fixed. I don't think what occurs with the VT30's FBr is the same as the Floating Blacks on the VT25's so it is possible what is happening on the VT30's is a flaw by their definitions but the VT25's were designed to function the way they do. While not an elegant design by any means it is what they claimed the set was intended to do.

Bottom line is you should pursue the issue I'm only relaying my experience which was stopped dead by them. I have accepted I will have to live with it or replace the set myself & I think that is where you will wind up too but maybe you'll fair better than me?

To my knowledge no Panny owner here has had this "fixed" on these sets. I think one guy in Britain or some such place got a VT30 replacement after a long battle but their laws may have played a role in that... On the plus side you might be the first & only guy to win this one.....

My VT25 broke less than a year. The service guy came to replace a few fans. He also reset all my tv settings. =( Now, I'm wondering if my TV still have the James Cameron firmware update. This is what my tv show when I select the TV Firmware Version option

TV: 0100-5330
STAT 1: 01010-20202
STAT 2: 00000-00000
STAT 3: 0.11.0
HDAVI: 5


Can someone verify that this is indeed the latest James Cameron Firmware version? Thank you so much for your help.

Thats a bummer. I will call back and see what they say. I refuse to have this issue. I paid 2 grand for it and its just not right. A swap for the VT30 won't work as there is no comparable match, but if they can't fix the VT25 then I am at least hoping I can get the 55' VT30 and pay an upgrade or something along those lines. At this point I would be willing to do this.

Matt I would encourage you to see if you can get a satisfactory resolution. I was going to try with my extended warranty but the company went under so I can't now. Panny service in Canada is awful but is better in the US so you may fair better. Good Luck!!!

I just wanted to let everyone know. My vt25 has the brightness fluctuation, but I was watching Green Lantern in 3d and did not notice any fluctuaton during the movie at all. Then I got to tinkering around in 2d mode. THX is what I normally use, then I switched to CUSTOM and all of fluctuation is gone. My settings are D-nice's with service menu offsets. Watched Transformers dark of the moon again last night and no issues at all. The first time I watched it was in THX mode and brightness was all over the place. Some of you might give it a shot and see what happens. CUSTOM on my set seems to fix issues for some reason or another
post #10514 of 10650
I bought the set boxing day last year. Got 1500+hours on it.

That leaves 2 months to the original warranty, and then I have 2 extra years of extended, the problem is the extended is also with Panny, not the retailer. Although I'm pretty sure Panny will let my retailer handle the warranty (they are Panny's authorized repair center in the area).

I haven't been overly bothered by the FBr issue since the set is not in an extremely dark room at the moment, but I do have some burn-in (or as some would insist, permanent image retention). I re-ran the slides again for a full day last week and the burn in is still there. Obviously have to be anal and look at it at the right angle/viewing distance to see it, but once you know it's there it's bothersome.

But the thing that annoys me the most, and I beleive it may be an upscalling or calibration issue(?) is a flickering effect I get when displaying content that has contrasting colors close to each other. I get a rainbow-like effect. Hard to describe, happen mostly when people on newscast etc were clothes with contrasting designs or lines.
To give an idea this

or this

are typical images that would produce this effect. The contrasting colors seem to merge together creating a flicker, and rainbow effect. It's like judder or phosphor trails..

That's really bothering me. I'm using Dnice's calibration settings and haven't flashed with 3.5 firmware. I've tried playing with the settings but nothing seems to prevent this from happening. Since I seem to notice it mostly on newscasts, I assume the image processing from both the TV station which doesn't capture it in HD but upscales/broadcasts it to 1080i, and the TV that further scales it up to 1080p, might have something to do with it? But if it's an issue with the set, I can't keep on living with this flaw.

So I may use the burn-in issue first to see what they offer, then point out this other issue if needed. As for floating blacks that would be a last resort since they claim it's a feature, and not a flaw.

Thanks and I will definitely talk to them and see what I can get done. I feel like I am not getting my money's worth since the set is doing something that is not supposed to happen.

I never have a problem in 3D mode. It is always in 2D mode. To be honest, I don't ever recall any fluctuating brightness in 3D mode. Perhaps its there and I don't see it because of the glasses or maybe it doesn't happen at all in 3D mode. I had my set calibrated earlier this year in the spring and the ISF tech noticed it as I showed him examples. At the time I had THX mode enabled. After calibration the problem still persisted. The calibrator calibrated in Custom mode, but even in Custom the problem is still there with the fluctuating brightness.

Can anyone tell me if getting your A board replaced wipes out the calibration settings? I understand that everything goes back to the factory settings, but if you plug in the same settings as you had before will they still work as intended or will it be different since there is a new A board?

yes it will.
Do a backup before the change of the A board.
Quote:
Panasonic has provided a means to back up all of the factory
settings to an SD card, which can then be restored from the SD card
back to the TV. Its intent is to provide a means for techs to
backup/restore the factory settings when a a board swap is
performed without having to go through the complete alignment
process. However, it would appear to be a good way to preserve
the original factory setup of your TV as a backup in case your
Service Menu adventures go awry.

Creating the backup is quite a simple procedure:

* Place a properly formatted blank SD card into your PC's
SD slot.
* Right click an open area in the SD card's file manager
window, hover your mouse over "New" in the context menu, then
select "Text Document" from the flyout menu. A new blank text
document will be created with the default name of "New Text
Document.txt"
* Rename the new text document "boardreplace.pwd". This
should be the one and only file on the SD Card.
* Turn on your TV
* Insert the SD card with the new file into the TV's
SD card slot
* The TV will automatically open an on-screen display
for the procedure.
* When prompted, enter the password "2770" using the
remote control
* The TV's configuration data will automatically be
copied to the SD card.
* At the completion of the procedure, turn off the TV
and then remove the card.
* Store the SD card in a safe place and hope you never
need it.

If the backup is ever required, you can restore the backup
to the TV by inserting the same SD Card back into the TV...
but when prompted for a password, use "2771" to initiate a restore.

A question to all VT20/25 owners...

Have you noticed an increase in the buzz sound of your TV through time?

Mine now is a bit too loud, but it used to be very quite before, so is this natural or should I be worried?

that is one aspect of the VT25 that I have not experienced. I am at 1600+hrs.
A little personal info I have found on myVT25 58.
When new under 200hrs,the color saturation through the
grey scale(APL) was decent.
at 200hrs,the first noticeable black level loss. minimal. color still decent and Saturation across all APLs.
AT 600hs major volt jump and scary black level loss. Contrast went whacky and color saturation went bad at low APL in high gamma (2.2) and had decent color at high APL.

With low Gamma it was reversed. (1.8) had good at low APL and bad at High.
It took 100hrs to settle back to pre jump user settings and
a better gamma across all APLs, still worse than before the 600hr jump.
as the tube aged more and more the color and balance of saturation through all APLs improved. I needed less color intensity settings than
new.Went from high 40's down to high 30's.generally regained a love for the picture.
During all this time, never saw a black fluctuation.
Now at 1500hrs, a minimal black level loss, a hit to the color saturation again.
BUT NOW I have the black flucuations and this TV is killing me with annoyances during shows, movies, ect.
I have tried all settings, trying to minimize it. No luck.
I learned that the volt increase really messes with color saturation. That given time the panel catches up. That is fine. Apparently the volts get high enough to trigger the black float. I have no idea if it will improve with panel age like the color does.
Just some of my observations.
post #10520 of 10650
Some very good observations Cal... My G20 definitely got worse on the FB's as the set gained in hours. I only watch movies with a LED shining into the CATS sensor now for picture stability though it does wash things out some admittedly.

I can't believe they did this with their flagship set in the VT, ludicrous......

damn. I hate to hear the fluctuations get worse.
I read about the led on the light sensor.
Do you use the USB to power it?

Yes but I use the USB on my WDTV media player to power it not the plasma (though that would work I expect) as I only turn it on for moves where the 2.35:1 really makes the FB's noticeable. I do find if I use THX with the LED light & a Brightness setting of about 50 it looks pretty good & doesn't look as washed out on darker scenes & there is plenty of detail for brighter scenes.

It's certainly a compromise but one I can live with it this way & am actually enjoying my set lately after being frustrated with it for so long. It doesn't take much light to trigger it.

I have tape over the back of the LED light with a small hole to let just enough light through to make it work & not be noticeable when shining at the front of the set.

I didn't do a backup, but I took a photo of ALL my settings before they did the swap. All the settings are back to what they were with the new A board. My main concern is will the new A board interpret these settings differently (since it is a new A Board) or will there be no difference?

I do not believe the new A board will not function like the old one.So the settings should react the same.
I understand what you are wondering.

I am curious about the hours and programmed volt increases though.
Please post what the new board does for you.

I'm sure the hours on the set have been reverted back to zero, but who knows. I have tried to check that before, but was nervous that I would do the wrong thing so I did not attempt to do it. I am still getting fluctuating brightness levels. The picture on the other hand looks pretty sharp, but I think I am getting more crush now. Could just be me though.

that would be consistent with the reports of better black levels. IE lower MLL.
Good thing. :thumbs:

Please post your repairs done by Panasonic for the VT-25, they are not acknowledging a fix for my TV. Why some are getting the new boards replaced and others aren't is confusing me.

I thought the black levels got worse over time with the VT25's. I know that the VT30's are improving over time. The mll's got lower on that TV form various professional reports.

From my understanding people with the VT30's have got their A boards replaced and the problem with fluctuating brightness went away after the swap. I, however, still am dealing with the issue after a board swap on my VT25.

people who have their A board replaced reported an improvement in Black.
Seems the A board resets the voltage to
new condition. So that is why I said what I did.
Sad thing, it does not last.
