I purchased a 65vt25 in December. Does anyone keep all the packing material and box? I'm getting sick of dodging it in the garage. Would I EVER have to ship it for repair?
post #10234 of 10650
I just moved and it cost me $250 for them to pack my 58" tv because I didnt have the original box. Put it in the attic if you can. I saved their box incase I move again.
post #10235 of 10650
I'm the type of guy that keeps the box for everything, I'm serious, I mean EVERYTHING! Since I live in an apartment, I flatten out the box and hid it under my bed. I then stuffed all the foams inside of other various A/V boxes that I had stashed in the closet (shitload of them ranging from now back to 25 years) and kept a log sheet of what's in what with MS Word. Interesting to read it from time to time of knowing what's hidden in the closet over the decades.

Got rid of mine after a couple weeks. 65-inch was just too big to keep around

I know this has been addressed, but I can't find the string. On my 54VT25 whenever there is a single color background that grades from light at the center to dark at the edges, instead of grading uniformly the color darkens in a series of concentric rings. This has become more common and more noticeable lately, and occurs with both compressed signals from cable and with full 1080p signals from my blu-ray player. Is this a processing error, a calibration error, or a component in the set failing?

Thanks

The effect you are seeing is posterization or when applied to HDTVs more properly called false contouring. It is present in any digital system that has to sample a change in color graduations. Analog CRT would not have suffered from this effect because they were analog. Anytime you try to capture and display video gradients with digital image processing an unintended artifact will be color quantization. Temporal posterization also occurs with moving images as in video.

Manufactures try to reduce the impact by dithering the edges and next temporal images, but this will only do so much. The higher image quality the more likely this is to occur given the limited sampling bit range.

I doubt that your TV is getting worse. This is deep in the imaging processing chips and you would have a complete failure of the picture if a chip is generating an error. Most likely you are starting to see this the more familiar you get with the picture. Unfortunately today's optical system are not quite as advanced as you eyes.

Set your display to 60Hz and see if it improves on BDs. On cable, it's likely in the source due to compression.

more commonly known as Banding.

So I called Panasonic Concierge service about the "cracking" or "popping" sound that occurs from thermal expansion and contraction of the bezel on my 58VT25.

The CSR said that they would ship the felt material to the local service station and give me a call when it arrives so that I can "pick it up and install it."

What a joke. I'm supposed to travel to their facility, pick up the material and install this myself?

I then asked the CSR about any fix for the "buzz" and she replied "it's the panel, you're gonna get that."

I've always been a Panasonic supporter, but after buying this $3000+ TV, I've gotten me a real bad taste in my mouth.

Let's hope it "nukes itself" in my 4 year warranty period so that I can get a newer, hopefully more sorted, model.
post #10242 of 10650
Thought about calling back and talking to the Manager of that department as long as you have the Manufactures warranty cannot see them try to get out of it, my .02 cents.

A buddy of mine just had his kid crack the the diplay and is now making a buzzing noise. Can they be repaired at a reasonable price or just buy a new one. What do you do with the plasma, sell it for parts?

If the panel is cracked, replacement is possibly the easiest route. Although it certainly can be repaired. You might also suggest to him that he consider one of those ultra-super warranties that covers accidental damages.

Is it normal for the vt25 to look like crap during pans? Everytime I watch sports and the camera pans the picture looks choppy and not smooth like my old 42px60u. When I got the tv I went from comcast to directv. So does directv suck or is it the tv?

The VT25 will faithfully reproduce every bit of motion judder that exists in your source.

Hi scoop26.I have the same problem with my vt25 except my lines are down in the left hand corner.I had a Panasonic TV tech come out and said this was a common issue with plasmas.Not burn in.He offer to replace it but you might end up with the same problems.I might seek out a second opinion.Still under warranty.
post #10249 of 10650
So I ended up taking the GT25 back cause I found an amazing deal on the VT for just $200 more! I couldn't believe it! I priced matched it. So for 200 more I got a significantly better tv and a pair of 3d glasses. It was the same price as they had the 50st30 on which is nuts, I guess they just want to clear them out. Canadians PM if you want to know where you can get it for 100 buck cheaper than the MSRP of a "50 st30

Couple question, unlike the other glasses I bought, these ones do not appear to charge, so I am wondering how long the battery is gonna last? and how much are they to replace?
post #10250 of 10650
Also upon examination with a light I see what appear scratches in a few places that extend full length horizontally across the screen and appear to be in the inner screen. Also there are some hairline vertical ones in the bottom portion of the screen that are not straight. The are only visible with a light and at certain angles.

Could this be a cracked inner screen? I doesn't effect viewing but I am concerned about it.

If others could take a flash light to theirs and look at the screen it would be greatly appreciated.


Edit- I figure it's just how the screen is, if it was going to crack it would be like a spiderweb effect wouldn't it? And the scratches that I never notice unless I'm a foot away and can only see with a flashlight at certain angles shouldn't be much of a concern.

So after having my VT25 since last June and putting around 2200 hrs on it verified from the service menu i can say that my floating black issue has been severely reduced if not gone at the moment. Its been around a week since I've noticed it, and i try to watch for it when watching movies at night. When I first had the TV i didn't notice the floating blacks till around 500hrs, and it seemed to be at its worst around the 1000-1300 mark. I can't explain any of this, but I am happy to see it at its current state. I used the break-in guide and settings from the D-nice post.

I don't post much on forums, but i was compelled to share my VT25 experience as it seems to get bashed a lot. Its been a great TV for me and well worth the price I paid for it. I'm currently contemplating getting it calibrated by Barry VanDenBerg from Orlando, FL, but not sure if I will get my money's worth as the picture with D-nice's settings is very good. If anyone has any thoughts on this let me know.
post #10252 of 10650
I have had my VT25 since September and did not notice floating blacks until last week when I watched Harry Potter: Deathly Hallows Pt 1. I do use Idealume Backlighting when watching movies and still noticed it. I checked out ceratin scenes of The Dark Knight last night and also noticed floating blacks. I'm not sure how many hours are on my VT25 but I will check. My wife claims she seen brightness fluctuating while watching broadcast tv. Maybe I'm approaching peak hours on the panel for floating blacks? Hopefully it will start to diminish.

CoachMcGuirk,

A professional calibration is really worth it. I had my VT25 calibrated by Gregg Loewen who did a superb job.
post #10253 of 10650
Thought I might share my ongoing issue with the Floating blacks and Panasonic's response:

I bought the P50VT20 (British model) in November and was delighted with it (still am).

The floating black issue became manifest over the last few months and back in early April decided it was a real issue. It was certainly very distracting and as a purist with my sets found it made it very difficult to watch movies with letterboxes (though I stress that it also happens on full 16:9 content but it is harder to identify). I watch in Cinema or THX mode and it happens on both.

I contacted my Panasonic store in Lincoln where I ourchased it, and they said they would send it on to their authorised repair centre in Grantham.

About two weeks later on 12th April I had a call from the shop asking when the set could be returned. I asked what the problem was and the solution and they said no fault had been found and as such were returning the set. I said this was unsatisfactory and was advised to ring the repair centre. The woman there was very unhelpful saying the problem was evident and that I shouldnt follow things written on internet forums "as anyone could write anything." After suggesting she was insulting the consumer she suggested that I bring in a selection of Blu Rays which I duly did.

Two weeks later and she rang and asked if i could come and show them the issue which I did. They saw it and said they'd video it and send the footage off to Panasonic.

Two weeks later after not hearing anything, I finally rang the repair centre and they said it was now in the hands of Panasonic and that I could expect to hear from Panasonic. One week later, guess what, no contact, so I rang Panny customer services only to be told that it was still in the hands of the repair centre. I rang the centre back who then spoke to Panasonic (apparently a miscommunication) and said I woukld hear from them either by letter, email or a call.

I rang Panasonic a few days letter and asked what was going on and was told I could expect a letter. Yesterday, after not hearing anything again I rang Panny and was told that according to their records no letter had been sent out nor should I expect any contact!! I described the Floating Black issue to the man (again!) who proceeded to say it was a "feature" of the 3D televisions. I said in that case it was mis sold and was advised to ring my shop. This is where it gets tense:

1) I asked for a refund. The manager said no.
2) I said it had been descirbed as a feature of the set. He said if it's a feature then the set is working correctly.
3) I said it was never sold as having this feature. If it had been I would not have bought it. It had therefore been mis sold/mis represented.
4) I also said, if it is a feature, why is it not listed in any of the documentation. He asked what documentation, I said the manual.
5) I proceeded to say, if it is a feature and the TV is designed to do this, why did it take such a long time to identify, and why did the repair centre send the footage off to Panasonic.
6) I suggested it was not a feature, but I am being fobbed off with that in the hpe I will remain silent.
7) I asked the manager if he would bve happy with the floating black issue. He said "if it's a feature of the set then yes." I said "but I was not aware of the issue" at which point he said 'we're not getting anywhere with this.'
8) I asked for a final time whether he would give a refund. He said no at which point I said my solicitors will be involved.

So there we are! Wonderful service. Sorry Panasonic, you have lost a previouslyt loyal customer. I am sick and tired of being held hostage by large corporation (especially when the manager said "we put customer service first"). I will challenge these legally, it's entirely unacceptable

It's great to read this, I hope mine behaves the same as yours when it reaches those number of hours....Do you have Harry Potter and the Deathly Hallows or the Dark Knight blu rays? Could you verify you don't notice any floating blacks in any of this movies.

Just to let you guys know I'm a 50" VT25 owner with well over 2k hrs on it and the fluctuation of the black levels in dark scenes is no longer an issue with this TV. At the beginning with over 1k hrs it was doing it pretty bad but it seems as time goes on this TV seems to have stabilized. I just tested this with V for Vendetta in the alley scene with the finger men and also the roof scene just before he blows up Parliament. I don't know what happened but it's not doing it in any dark scenes even when I'm watching a crappy cable analog feed.

So far I've I'm pretty happy with my set and even happier that it doesn't do this anymore...

That's probably why I've only seen a single light example of this on my Best Buy display unit.

I have a 58VT25 in AZ for sale in case anyone is interested.
post #10259 of 10650
has anyone who owns this TV noticed the increase in black levels? I'm curious because I'm coming close to the dreaded 1500 hour mark and was wondering if its really noticeable.
post #10260 of 10650
I have 1,680 hours on mine and I haven´t noticed any visual increase at all.
