Thanks for your calibration report. I've added it to the list of owner reports (post # 2) that's linked at the bottom of my post.

Finding out about your report has taken so long because I'm not able to read all the display threads.

If anyone knows about owner calibration reports that haven't been included in the reports list please let me know.

Enjoy.

Hey Guys,

Went in to best buy yesterday looking for a bedroom TV was thinking about getting the 50ST30. But they had an open box 54VT25 so I ended up getting that for just under $900. Good idea or bad? March 2010 build date got it home no issues so far.

Lucy, Just check to make sure there is no screen burn in. Best Buy is known for running their demo TVs in full torch mode especially if it was a 3D demo set.

Put up a white screen and look for ghost images (burn-in), or large numbers of stuck pixels. If you don't see anything that looks awful to you, enjoy your new display.

If your set has been a demo, it might have burn-in due to the way BB runs their demo source material.

HDMI IN and OPTICAL OUT SIMUTANEOUSLY?


Hello,

I have looked through this Official Thread and have had a hard time finding what my problem is.

1. I am connecting my HTPC to my Yamaha RX-V671 receiver via HDMI, then from the receiver to the TV.

- the audio works great on my Yamaha and is full 5.1

- However, i was hoping to back feed the audio from the P50vt20 into my receiver to drive the 2nd zone.

to do this, i bought an optical to analogue convertor.

2. but i have found that in this configuration, the audio is not being fed out of the optical port.

3. when i connect the HTPC directly to the TV via HDMI, I am able to get Optical audio out - to my convertor and then to my receiver (of course on 2 channel, which is all i want)

my question is:

- does anyone know if it is possible to have the 5.1 through the reciever and then get audio out of the tv?

- or is it that my reciever is only sending video and not audio?
- but then again i do get audio out of the TV speakers.

- would 1.4hdmi cables make this work?

it seems that is probably configurations in both the yamaha and the tv that i have messed up.

it is very frustrating, but i want this setup so i can feed music from computer to the main speakers and to my outdoor speakers (via zone 2 on the yamaha) at the same time.

thanks for your help in advance!

The AVR should be sending audio to both the TV and AVR via HDMI. Check your TV speaker settings and AVR. As far as HDMI cables there is no 1.4 just stick with what you have .
post #10540 of 10650
Well there's no such thing as 1.4 HDMI cables (true) but you still need to make sure you have the "High Speed HDMI cables" to be compatible with the higher flow of data shared my 1.4 HDMI connectors, needed for 1080p and +. "Standard" cables are rated up to 1080i only.

Haven't posted in here in a long while... I haven't had any issues with this set
until today. What in the world is this?

I have switched HDMI cables, swapped inputs in my AVR, and switched inputs on the TV as well. Its not burned in, but a weird block of colored lines that slightly pulsate. Almost invisible with bright pictures on screen, but highly noticeable with dark scenes.

Have any of you seen this before? Any ideas?

Have you checked ground loop problems between house ground and cable TV ground?

I had such interferences once and had to isolate the Cable TV grounding to mitigate the problem.

All the best,

Michael

It's been a long time, but when the set was first coming out I remember several pictures on YouTube from different people with the VT25 having similar active quadrants. One stayed in my mind where the guy said he was so frustrated that he hit the top of the set hard and the problem left. A search should find the uploads , and personally, I would NOT TRY HITTING IT.

Best,

Paul

Mine looked like that and had it replaced after 5 or 6 months.

Yeah, that looks very similar. I have had the set for 1 year and 1 month, luckily I got an extended warranty with it.

They weren't able to repair your set? How long did it take them to get you a replacement?
post #10546 of 10650
Even though the original warranty is over, I would try my luck with Pani first especially if you're in the US. Dealing with extended warranty claims can be a PITA...

Or, try both and see which one reacts best.
post #10547 of 10650
Place I bought the TV did not want me to have to go through Panasonic so they replaced it for me with-in a few days of it happening.
post #10548 of 10650
I had exact same issue, but in the lower/left side of the screen. It had nothing to due with switching cables... just appeared one morning.

Local Panasonic support came out and fixed since unit was under warranty. I think they replaced a "D" board. The tech said all the boards are assigned a letter since they do multiple things. I should have asked how much it would have cost to fix outside of warranty... but I didn't. Unit is now out of warranty and I'm hoping I don't have any other failures

Hi All, just came across this amazing forum and it's certainly a great learning experience. I just got myself a VT20 after reading through the site. However, I have a small suspicion about my unit.

When I turned it on, I noticed at the bottom portion of the screen, where the vierra cast menu normally is, there seems to be some sort of image retention, or burn in of sorts. The panel is not showing any content (in fact just waiting for something to come in on HDMI 2), but there's clearly something visible there.

Being a little suspicious, I checked how to enter the service menu, and try to get a read out of how many power on hours the panel has had. The values read:

Time:04411:00 Count:0000573

Having just gotten the panel, I'm not sure if these values basically mean the panel has had about 4000+ hours of use and it's been turned on/off about 573 times.

I'm planning to give the vendor a call on this, but thought I checked with the experts here if my interpretation is correct.

Also curious, if I may, would be the amount of hours your panels had when you received it? From the other threads or post, most seem to come with about less than 100 hours on the panel.

Hope to hear from you guys soon on this as I suspect I've been taken for a ride. It's supposed to be a new panel, but, didn't seem to be the case. Hope to hear your thoughts on this bits before I engage them and panasonic. Thanks in advance everyone!

It's reasonable to assume that you bought a display model. VT20 was discontinued a while ago and display models are about all that's out there. Normally a new panel should come with no hours. As for the observed image retention, hopefully it's not burned in and will dissipate over time.
post #10551 of 10650
Hi rdgrimes, thanks for the inputs. I'm guessing as much now as well. I'll probably give the vendor and panasonic a call.

I'm just a bit concerned if the vendor decides to replace a new unit for me, he could very well replace it with yet another display unit, BUT with the power on hours reset to zero. Not sure if this is possible to be done by a layman or requires a panasonic engineer to do it?

Hopefully the procedure is not so straight forward.

I suppose the obvious question, which you probably don't want to hear, is why are you doing business with a seller you don't trust?

It really hinges on how much you paid for it and how much trouble you want to go through. Panasonic is going to tell you to deal with the seller. What is the seller's return policy? In any case it's got a couple years of time on it.
post #10553 of 10650
Hi rdgrimes, thanks for the note and you certainly hit the spot there. I'm leaning towards a refund at this moment.

Sad thing is this is quite a reputable vendor around here, but I'm probably not going to bet on it that they can be trusted. Thanks again and will keep you guys posted
post #10554 of 10650
They will take back the unit and MAY have one more unopened unit, but on the other hand they have offered to let me take the Sharp LE830 52 inch for a slight markup. What do you guys think? Should I take the unopened unit or go for the LE830 which is a LED/LCD? Not sure how's the performance in comparison to the VT20.

While I'm sure it's a fine TV, I don't think it's really in the same league as the VT20/25. But you're comparing apples to oranges.

Got to agree with you there. A low end Sharp you will never be happy with after owning a VT20. Its just not a good deal, especially since you must throw in some more cash. Doesn't your vender have any VT30's you can replace it for? What size is your VT20/25?

Or maybe take the next size up in a GT30. Thats probably what I would be aiming for.

Just wanted to report that I've been experiencing the FbR issues for the past year+ on my 58" VT25. Always during dark scenes with my PS3 blurry playback and/or cable. Didn't realize it was an "issue" until visiting this forum. It was something that I'd always noticed and bugged the hell out of me. Thought it was just how this plasma did its thing. Naive I know.

The Panasonic tech support woman tried to convince me that it was my PS3 Bluray player/disc that was at fault. I simply told them I tested it on my friends samsung television, same player/movie/cables etc. and experienced no such phenomenon. Insisting that it wasn't my PS3 or Cable box that was at fault. The result? I now have someone coming to check it out this coming weekend.

I used this as my guide: http://www.avsforum.com/avs-vb/showp...postcount=3775

Will keep all posted on any developments.

That fix is just for the 2011 models, there is no fix for the "floating blacks"(FbR) on the 2010 models.

So uh, should I call Panasonic?

Can buzzing suddenly get worse? I have a 58VT25

Last night my roommate wakes me up over what he heard from the tv, so it must of been bad. He claimed the tv was making a loud buzzing sound. Enough for him to be like, "holy #$%!". We've had the tv for nearly a year, nothing like this. Yes, it buzzes, but never enough to be a bother, only slightly when a full white screen. Plus, my roommate never noticed the normal buzzing this whole time.

I brushed it off and went back to bed until the next day when I got home and turned it on.

1: I started VierraCast from a black screen, nothing that caught me off guard just yet.

2: Selected and opened Netflix, holy bleep, I leaned forward it was so loud.

When the red netflix screen appeared, it was 10 times louder than ever before. Then when the blank white queue screen came up, even louder, so loud I thought it wasn't going to stop and pop something in the tv. From 10 feet away it was strong enough to tell it was coming from behind the tv and more localized, like a part, not just the normal ambient buzz.

I exit Netflix and tried again from a black screen, this time is wasn't as loud. So it seems to be worst when first turning it on, enough to freak me and my roommate out after nearly a year of no issues. I've always heard buzzing from day one, only a white screen would annoy me, but that's rare situation, and nothing like what it's done the last 24 hours.

I've heard of people getting the TV and not liking the buzz. Then they get it repaired or replaced and some how it helped and made it more tolerable. Has anyone experienced this? Where out of no where it just got so much louder, enough to freak you out, not just annoy?
post #10560 of 10650
I own Panny VT20 properly broken-in and used for 3000+ hours.

When I play 3D content I find the brightness too low, possibly (?) due to the nature of active shutter glasses, to the extent that I prefer using Dynamic mode.

I know using Dynamic mode is a risk factor which may cause temporary image retention or even permanent burn-in if the plasma is not properly broken-in.

My questions are:

1) Is there a possibility that IR or burn-in may occur despite my proper break-in process in the past and total hours viewed when I use Dynamic mode?

2) If your answer would be "IR may occur but burn-it would not", then my next question is: Would frequent IRs eventually cause burn-in? In other words, is there a relation with how frequent IR occurs and burn-in? The reason why I am asking this question is because, as long as IR does not eventually lead to burn-in and it disappears within a certain and relatively small period of time, it would not bother me.

Thank you!
