post #8581 of 9971
Ive been in the audio sections of this forum for a bit and finally made my way over here. I bought my ST50 back in August for a great deal! I have been enjoying it ever since. I have no complaints. It's a great tv, amazing picture, good blacks, etc. The only thing is sometimes I will look at it and think 'I wish I would have got the 55.' Other times I will look at it and think, 'no it's plenty big, looks great.'

^I have thought about selling it and upgrading to the bigger one though
post #8583 of 9971
Cast aside my fears of getting a buzzer or an IR magnet--in this life, fortune favors the brave--and should be taking delivery on my 60ST50 in seven days. Wish me luck! This will be my second plasma, my first being a Samsung PN50C550 from the Spring of 2010.

This may help with aging the unused pixels and minimize the sidebar brightness difference on full screen content. I used this feature on my ST30 for like 6-9 months on med then low now I don't use it at all and have no problems.

I am using a computer with Windows Media Center to the TV. As a result its always a 1080p signal and the option for gray bars is grayed out frown.gif I can set it in Windows Media Center however. I may do that with a dark gray side bars. Thanks.

This is at the default "PC" setting for the TV. The text has a green tinge to it, is a bit fuzzy and just in general the picture doesn't look clean. Are there ways of adjusting either the TV set, the video card settings or both to make the picture look sharper and better? I realize that this isn't a high-quality LCD monitor I'm talking about, but there's got to be a way to make it look at least somewhat better than it is right now...

Thanks!

Is your desktop video card 1080p? I have my HTPC hooked up HDMI as well and it's stunning on my GT -50. Check your video card settings and set it to 1080p. If it cannot you need one that does.

Hi Lads
Another refugee over from the audio section, and I’ve looked around this section but without luck so far. I’ve had a new TH-P60ST50A for a week (wanted a GT but Panasonic OZ decided no GT’s for 2012) and it has a great picture, but at start up but not always the screen as it comes on will have black spots (mainly in the middle I think) for about a second then disappear, never to be seen again until the next turn on and only if the unit has been off for numerous hrs. I’ve tried googling but I can’t find any reference to this issue. I don’t know if I should be concerned or not? I have a TH-50PZ700A and a TH-P42GT30A and have never seen this before. Any ideas be greatly appreciated, thanks

Here are some BUZZ and POWER measurements using the free AVSHD 709 calibration DVD.

BUZZ
To try to quantify the buzz, I took a RADIO SHACK 33-2055 Digital Sound Level Meter to the top rear of the set. One spot to measure is top center down about 2 -inches so you are on the solid sheet metal between the holes. The only way I saw to get a consistent reading was to place the microphone end right onto the metal with light hand pressure. If you hold your ear right up to the metal you can hear the buzz. I measured around 65 dB on the meter. This is on the Screen #3 of the BASIC SETTINGS which is mostly white. Also I get 70 dB on the AVSHD Main Menu screen, using a spot 3-in down and 3-in over from the the top the set, on the side with the HDMI inputs. Again by pressing mic end flush onto the solid portion of the sheet metal beside the holes. Unless I press the mic right onto the metal I do not get a reading or it is low maybe 50 dB. I use 55ST50 stand on a TV table (not wall mounted).

Note so far I am claiming this set is not bad for buzz (yet anyways, by my ear). However, back in '74 I did attend an ELP concert in Philly...ouch. My build date is like July_2012 even though it was delivered via AMAZON in Dec_2012.

POWER USE v. CONTRAST
Using Kill-a-Watt meter I looked at power consumption vs. CONTRAST. To do this you need a test screen with a mix of black/white levels. So something like the BASIC SCREEN #5 with the test patterns and blue overscan markers at the borders. I found power consumption rises rapidly up to 85 contrast and then levels off, and power consumption actually drops off above 95 contrast. Below 85 contrast the power consumption drops about 10-watts per unit of CONTRAST. So if you set CONTRAST for 80 vs. 85, your are probably saving 50 watts. For reference DNice settings are 76/78 CONTRAST and CNET is 82.

Anyways I am not claiming the best science here, just messing around a little. Just found the free AVSHD DVD yesterday, after one of you mentioned it recently in a post.

Good work on the sound measurement, but it would be a lot more interesting if you chose one exact spot/orientation and took measurements with the TV off, with the TV on with a dark screen, and with the TV on with a white screen.

It would also be helpful to have the actual values of power consumption. At 85, what were you measuring for watts?

Do you mean random splotches of black and grey that flash very quickly? Both my V10 and GT50 do this. I asked about it when my V10 developed it and never got an answer. Either way, its nothing to worry about.
post #8591 of 9971
I asked this in the Denon AVR-XX12 thread, but didn't get an answer so I'll ask here. I'm experiencing an overscan issue with my Denon 1712 and ST50. If I connect my PS3 and XBOX 360 directly to my ST50 via HDMI (I tried HDMI 1 and 2) using zero overscan (HD Size 2 on the ST50) the image fits perfectly, but when I connect my consoles to the AVR and the AVR to my ST50 the image is shifted over to the right slightly leaving 1-2 rows of black pixels. Anyone else experience this? Any explanation for this?

No it dosen't flash and there isn't any grey either. Thinking about it more the best way to describe it would be that it looks like grit on the screen ( like it's dirty film, 8mm film), but it's gone so quick. the other weird thing is the smart viera splash screen before the TV screen fully lights up is also fine. Sorry about your issues fahrenheit but I haven't experienced those either

It sounds exactly the same tbh. It only occurs on a cold start (TV been off for several hours).
Here it is on my V10 but its difficult to film. You'll need to watch it in a relatively dark room and you'll probably have to watch it several times. You'll note the second time I turn on the TV, the frame is clean.

My wife and I currently have a 27" CRT in the living room that I'm looking to replace. We watch mostly SD TV content right now, with some DVD and Blu-Ray (our DVD player was dying so we went ahead and updated that already), with occasional video games (a few hours or so at a time every few weeks or so. I'm also an avid NFL fan, so there are days when I'd be watching a number of hours of football with the static elements on the screen.

Also, we're currently in an apartment but we plan to have a house in a few months, so I don't know exactly what the lighting will be like in the living room. I would assume that some combination of floor lamps and windows will be in play.

Given some of the concerns I've seen in this thread about IR and buzzing and what I'm looking for in a TV, would you recommend the 50ST50 for our living room use? Thanks in advance.

Anyone?
post #8596 of 9971
I own an older model Panasonic 46pz85u and am thinking of upgrading to either a 55" ST50 or GT50 (still deciding). My old pz85u was in a smaller room and the heat it gave off would make that room feel very warm after an hour or so. My new TV will not be in a small room anymore - it will go in a regular sized living room but I still intend to sit close to the screen (5-9 feet) to watch movies and I am very concerned about the heat issue. Will the heat not be that bad since it's in a larger room?

Also, Regarding the ST50/GT50 - are there any defects that people are experiencing? I ask this because I just bought a 55" Sony HX750 LED and noticed immediately that it has spotlighting in all four corners in black or very dark scenes (I probably noticed it because I'm used to my pz85u plasma which had a great picture and was great with dark colors). I was told that this is a defect that can occur large screen LED TV's so I am probably going to exchange the set. I've browsed through the last few weeks of this thread and didn't see any major problems discussed?

Only thing that would give me pause is the SD 4:3 content. You don't want to watch a lot of stuff with bars on the top or sides for the first few hundred hours as it will cause uneven panel aging and can make the letterboxed parts of the screen look different. So I'd only go plasma if you're going to upgrade to some HD TV service.

As for buzzing, I'm exchanging a 55UT50 as I couldn't stand the buzzing. But that's really just a crap shoot. Panels of the same model have different levels of buzz as some have posted comparing exchanged units side by side with the old one and getting one that's much quieter. Some are much more sensitive to hearing buzz (like me) and hear and get annoyed by it when others don't hear it or think it's distracting etc.

IR should be ok with your uses beyond the uneven aging if you watch too much 4:3 content. You can get some IR from gaming or watching ESPN for a few hours. But from my experience that went away pretty quickly (within a couple hours of watching other stuff). Now if it's going to be much longer sessions then you can get more stubborn IR that takes a much longer time to get rid of.

My general take on it--having bought and returned plasmas for other TVs is as follows.

If you're top priority is picture quality (i.e. you're a videophile) and you mix up content regularly (not playing the same game all the time, not having the TV on ESPN or other channel with static logo for hours every day etc.) then go plasma.

If you're not a videophile type and tend to have static things on the screen for long stretches and not mix content that much, then go LCD/LED. The picture quality just isn't worth the IR worries and having to change how you use your TV if you're not an a/v enthusiast. If you are a videophile, then you just have to way how much you want the PQ vs. having to worry about IR and change your viewing habits to limit it.

The viewing content and lighting conditions that you listed are all normal. Therefore I think that most people who purchased an ST would recommend it.

What you experienced is a defect of edge lit LEDs and has nothing to do with the size. There are no major defects on the ST series.

There are a handful of assembly plants scattered around the planet, so the country that it was assembled in depends solely on the country that the TV was sold in. The actual parts are manufactured in Japan then shipped in kit form to those various assembly plants so the parts are all the same, they're just assembled into TVs at a local plant.

All North American continent units are assembled in Mexico.

I saw a list of plants once but it was a long time ago and can't remember where the other plants are, but i think the European models are assembled in Czechoslovakia and the Asian market units are assembled in Malaysia. I also think they assemble some units in China, and they initially had plans to open a large Plasma assembly plant there but reduced demand for TVs caused them to scrap that plan and continue with the current plants.

yes the st50 definitely does not recognize avi files, which is a slight bummer.

Thanks for your reply. I plan on running D-Nice's slides for the first 100 hours to calibrate it, and would likely run the slides when we're not watching TV for a while after that to help age the screen through the first few hundred hours more quickly. Given that many 4:3 channels now present their content in letterbox format, I could use the zoom feature to eliminate that problem (though that would obviously have PQ issues). Using the pixel orbiter sounds like it would also presumably help prevent IR early on as well.

I will check into upgrading to HD channels, but we're in a contract with our provider right now, so I'd have to see what affect it would have on that before making the switch. If push came to shove, we could download HD versions of the programs we watch since most of our viewing is time-shifted anyway.

I did go to Best Buy last night to look at the 55ST50 they had on display and stuck my ear up to the back of it as best I could, and I didn't hear any buzzing. That was with a very bright image on its screen, though the ambient noise in the store may have covered up any buzzing that was present.

CNTRST WATTS
100 272
95 273
90 281
87 283
85 276
84 267
83 256
82 245
80 228
75 200

The above is at CNET Brightness=60 Gamma=2.6 Color=45 settings on AVSHD overscan slide5 on BASIC with 55ST50. If you plot this up you see the slope is really steep between 80 and 85 WATTS. Currently I am trying 80 CONTRAST and 61-62 BRIGHTNESS as my settings as a compromise to reduce power and perhaps IR.

Re: BUZZ
Further on BUZZ loudness quantification, forget the RADIO SHACK sound meter. Take your iPhone and download app Decibel 10th, its a free and highly rated sound level meter. The loudest spot on my set seems to be TOP LEFT (HDMI input side) there is a square grid of vent holes about 4-inch down from top and 6-inch over from side. I am using the AVSHD Main Menu screen, which is white, I measure max. of 63-65 dB.

If you want a quiet screen, go to BASIC #1 which is the all black one for BRIGHTNESS settings. I did not hear much effect of CONTRAST/other settings on buzz.

On white screen, I can hear the low level buzz from my seat if I turn my ear to the set.
It does not bother me so far. Presumably the sound is bouncing off the back wall (1-ft away) so I plan to look into how to diffuse reflected sound.

post #8607 of 9971
I recently had my 55ST50 calibrated. I was using the settings from Cnet before it was calibrated. When the pros tell you that copying settings will not yield the same results, believe it. Here are the before and after results.

Thank you for so detailed answer!
post #8610 of 9971
ive heard the "buzzing" quite often, but only on white screens, even when playing the color slides (brake in). i can actually hear it quite well when the slides are playing.


hey Risk235, i know you dropped some cash on the calibration, but would you mind pm'ing me the settings so i can see if it makes a hugh quslity difference in the c-net settings im currently using?


also, i asked if anyone knew the VESA numbers for the 55st50 on the last page? im trying to order a wall mount from monoprice and want to make sure i order the proper mount. does anhyone have an idea? the owners manual doesnt list it, i cant find it anywhere on line, and i dont really trust the BB people as most are ill-informed.

thanks
