Official Panasonic TC-PxxVT20/25 Owners Thread NO PRICE TALK!! - Page 116

post #3451 of 10650
I've had my 65VT for about 1 week, approx 15 hours viewing. I watched Casino Royal last night (Pan BDT350) and 1.5 hours into film in the centre of the screen the pixels started to break down and I heard a loud pop through the speakers. This happened again at approx. 15 min later. Any ideas?

Yeah sure... I'll run a test and post it in the Plasma Measurements area.

Edit: The results are in. There may be some slight issues due to resolution scaling that the TV had to do, and the fact that I compared it to a laptop LCD, but it looks like somewhere between 0 and 15 ms. I'll look around for a CRT and then maybe re-post it.

I checked the owner's manual for the p65vt25 on the panasonic website, it gives the exact lengths between the 4 mounting holes on the TV! good luck!

Is it a problem to run in this mode for day to day viewing? I like the pop better in this mode (maybe this mode just changes the contrast/brightness for you?) The room we will put this in is a little bright and I think the vivid mode would help with this.

I was in the same situation as you were by looking at the LCD's first and then reading up on them and moving to the plasma camp. I have the 54VT25 and although I have run it in Vivid mode, I moved away from it fairly quickly due to preference after having changed modes and settings. I plan to have it calibrated so I'm just waiting until that happens.

Maybe someone else can chime in who knows what they're talking about but I wouldn't think it would be a problem to run in Vivid. The only thing I can possibly think is that you might not want to run in Vivid 100% for the first 50-100 hours. Some people seem to be picky about breakin, others don't think it's worthwhile.

I'd leave it in THX mode for the first 100+ hours of the display. Not only is it better for the break-in period, you might even grow to appreciate its accuracy for movie watching over the pop provided by Vivid mode.

Also keep in mind, running in Vivid mode draws more power (higher monthly electric bill) which also shortens the TV's life. When calibration advertisements say they can lower your display's power consumption and prolong its life, most of that is done by just switching out of Vivid mode and turning down the contrast.

I agree, no one who has been at my house, young or old, hears any humming or buzzing from my 58VT25. Even my wife, who has excellent hearing, does not hear any buzzing or humming. I'll say again, I do not use the TV speakers but go thru an AV recvr. However, D-Nice said this should not have anything to do with it and I believe him. I'm just thankful I don't have the problem.

That's not meant to be a slam - I know everyone speaks very highly of them. They just more than likely have better things to do than answer PM's from a forum. Obviously if I had to have the set I would call them.
-Nick

I am not getting all PM's for some reason Call us so we know there are no hickups. PM sent. All VT25 are ready to roll.

Yeah vivid mode is a total puke fest. If for some reason you like it though, just wait till you've done your 100 hours of THX first.

Are the people with buzzing issues watching in Vivid Mode?
post #3460 of 10650
I've been playing some captured network TV shows (.ts files captured from HDHomerun) over my network via my PS3 and Windows Media player serving them from my PC. I've noticed that when there are bright highlights on the screen with sharp edges (like lights with a black frame) my 54VT25 emits a piercing tone (about 2khz) from the rear, sounds like a power supply transformer squealing. I haven't heard it from any other source so far. Any ideas?

Obviously they will be a lot more money, but they will correct any problems the Panasonic has, will have SUPERIOR build quality, video processing... you name it! We'll have to wait and see!

Well, considering Runco panels have never been particularly better than other panels in the past, this will be quite an accomplishment... especially if they stick with LCD.

Keep in mind that Panasonic manufactures plasma and LCD panels and Runco has to buy their panels from a manufacturing company (like Panasonic or Funai or somebody else). The "build quality" statement is also suspect. There hasn't been anything in the past in Runco panels that suggests superior built quality. That said... they have had good panels in the past, sometimes with more adjustment capability than other brands and sometimes with better "out-of-box" results than the large Asian brands. But calibrate the best Asian models and calibrate a Runco and you end up with images that are relatively comparable.

As a non-manufacturer, there's only so much you can do, even at elevated price points.

Runco is subject to the same technology limitations as every other brand in every display technology. LCD panels have motion blur and viewing angle issues. Edge-lit LED LCD panels have uniformity issues (flashlighting). And LCD panels are problematic for 3D because of the motion blur limitations. Plasmas have IR and potential for screen burn if abused. Customization of a display for a company like Runco is generally limited to cosmetics (different bezels and maybe different bases) and to what can be done in the software kit provided by the manufacturer (custom menus and settings, etc.).

Runco does make some kick-ass projectors... their Q750i DLP/LED projector is fantastic, for example, especially after calibration. The panel displays, historically, have been good but not necessarily better than Asian brands. With Pioneer gone, it would be interesting to see somebody step in and re-take "the best you can get" -- from what we've seen so far, the VT25 displays are currently "the best you can get" right now, though they are not perfect in every way.

And don't forget that Runco is no longer a privately owned company. It's now one of the brands under a larger corporate umbrella with new management. So far, the heritage of the company is being upheld in the projector line. It remains to be seen if the panel line is "moved" in any particular direction by the new owners.

These comments apply to current and previous years' models - you never know what might come along.

I have buzzing on my 58VT25 on THX mode with contrast and brightness at 50. I think I will return the set if it doesn't get better, I have had it for 1 day so far.

now we will start to talk about how the vt is buzzing just like i wrote last week what will be next how the tv has bad ghoesting when watching 3d the will buzz but it only comes from the back if not from the front like the samsung does anyone who says the can here it must be watching tv from the back
post #3464 of 10650
I can't hear any buzzing on my 65VT25 while watching the TV at normal levels with sound via the AVR. If I shut everything down except the TV and put my ear next to the vents in the back of the panel, then I can hear a faint buzz. For all practical purposes, my TV does not have any noise.

My buzz is audible at my regular viewing distance of about 10 feet when volume is muted. It varies with the content being displayed. Brighter \\ whiter images produce louder buzz.
post #3466 of 10650
As someone posted above, I would call Panasonic service for the buzz. Once they fix it, please report back what they found/corrected.

Has anyone recv'd their 2 free 3D BDs yet from Panny's purchase rebate program yet? If so, how long did it take? I can't even get my rebate status to come up on their website. I saw some posts back that some of you got yours almost right away after calling in.

I had this tv for about two weeks now... anyone else have it where it generates heat when on?

Warm air around the top twds the back where the fans are. That's normal and to be expected. Not hot but warm. My Comcast cable box puts out more heat than the TV.

sorry forgot to state .. heat from the front of the tv coming from the screen
post #3471 of 10650
I've always been an LCD guy but for several reasons I'm starting to consider a plasma. A few questions though I have about this tv in particular the 65 vt25. I've read and see some talk about green phosphor trails or something, is that an issue with this tv? Secondly, how is the 3D on this tv? Do you really see the 3D aspect as a selling point and something you are glad you got the tv for?

Also.. I will be doing a lot of gaming on this tv so is that going to be a problem with burn in etc?

I could feel a warmth in front of the screen, the first day or so. However, putting my hand on the screen it did not feel warm at all. This effect in the front went away sometime during the first week. I only feel a little warmth at the back top like I stated. I assume the fans are working but I can't hear them.

HHmm mine is still warm after a week and a half or two

I, and I feel safe in saying, many of us have not seen any green phosphor trailing. A couple have stated they do. The 3D is simply fantastic, better than you have seen. Not sure the 3D is a selling point. Again, many on here bought because of the excellent 2D brought about possibly by the 3D technology requirements. Yes the 3D is a great added benefit. Yes I am glad the VT25s are 3D capable and I have one!

Mine is also warm after 2+ weeks. I used an IR gun a few days ago to measure the temperature at five spots on the screen after the TV had been on for over four hours. I then measured the nearby wall temperature and the temperature in other parts of the house.

Upper Left 107.6 degrees (apparently heat does rise )
Upper Right 109.5
Lower Left 98.0
Lower Right 97.3
Center 102.2

Room Wall 79.3 degrees
Other parts of house 75.7
Thermostat setting 76

From this, I conclude the TV does put out enought heat to raise the room temperature. As our air conditioning thermostat is in another part of the house, this room will only get cooling when the rest of the house temperature rises.

so the tv does generate heat ... well my thermostat is on the other end of the room so it might effect me a bit =)

I just held a very good cooking themometer against the glass. On the bottom it reads 84.3 at the top it reads 92.3. The room air temp is 74. My body temp is normal. Just thought I'd throw that in. Yes, I can feel the warmth of the temps I've listed. Try putting a themometer on it and see what you get. It would be interesting if some of these TVs get warmer/hotter than others and why.

The cooking thermometer I used is very, very accurate. I bake quite a lot and really trust it (not cheap). I only measured at the very bottom of the glass and at the top. I didn't measure the middle because the screen feels the same until within about 3 inches of the top. That's where it was the warmest. No 100 degrees but I would guess your gun is more accurate than my baking thermometer at these temps.

As you are aware, IR guns are instant read. Does your thermometer take time to reach an accurate reading?

I can take my IR gun and measure my DVR...probably about 110. External drive on the DVR, 95 degrees. Then my AV receiver....maybe 120 inside. Let's move on to my 2 PCs running a total of 7 hard drives (95 degrees each), 2 GPUs (140 each), 2 CPUs (110 each), etc etc. Guess what, electronics generate heat.
