Official Panasonic TC-L32S1 Thread - Page 10

I found these on Wikipedia; they may apply:

Magnetostriction
Magnetic flux in a ferromagnetic material, such as the core, causes it to physically expand and contract slightly with each cycle of the magnetic field, an effect known as magnetostriction. This produces the buzzing sound commonly associated with transformers,[25] and in turn causes losses due to frictional heating in susceptible cores.

Mechanical losses
In addition to magnetostriction, the alternating magnetic field causes fluctuating electromagnetic forces between the primary and secondary windings. These incite vibrations within nearby metalwork, adding to the buzzing noise, and consuming a small amount of power.[38]

thanks for looking that up, I hope I did not get bad unit.

Funny thing is today. It did not do it. I tuned it on watched for an hour turned it off, Pure silence no buzzing.


Leading me to believe its not normal. If it was normal it would always do it. Or it would not do it.

I am gonna give it a burn in tonight all night, Backlight at 61 in Eco mode, should only be using, less than 70 watts of power.

Then turn it off in the morning. See if it buzzes.

No one else has heard this buzzing coming from the back panel after turning the unit off?

Come to think of it, since you mentioned this I remembered something I noticed when I was looking at an L32X1 in Best Buy a week ago.

It made a loud *snap!* when I turned it off... then started buzzing. It was buzzing loud enough for me to hear it above all the other TV's (although I was actually only about 6" away from it). I thought it was weird, but figured it had something to do with the Best Buy wiring. I turned it back on and the buzzing stopped.

So I think it's just something these TV's do when they are left on for long periods of time, then get turned off.

I don't think it's anything to worry about, aside from the annoyance; after all, I don't think any human likes the sound of flowing electricity.

wish people would post more screenshots and video of these Panasonic IPS in action

LG Super IPS and Panasonic IPS Alpha

Super IPS the pixels go like this <<< and on IPS Alpha they are vertical ||| which apparently makes the pixels closer together

my Dell 2209WA has an LG panel inside using E-IPS and the pixels match IPS Alpha vertical ||| and I'm really impressed with how vivid reds, greens, blues come out on that compared to the Super IPS

I won't use anything but IPS LCD's I have tried others LCD's and these are the best.

I have been reading that Sony SPVA are just as good but much deeper blacks

S-PVA panels found in sony and samsung TV's are superior for overall picture quality

where they fall short and this matters most to gamers is input lag, they have at minimum 40 ms input lag. only the 2008 A series Samsung's had low input lag but it was limited to 2 input ports and modes VGA input and HDMI1 relabeled to PC and ONLY when they are getting a 1080p signal on those 2 input modes. picture controls are almost all disabled in this mode and it does not look anywhere near as good as normal modes do as far as color accuracy and pixel level blurring so the panny's are still better than these now no longer made or sold A series samsung TV's

when put into this mode they are inferior to these panasonic's in overall color accuracy and had more pixel lag and some smearing or blurring due to it.

these Panasonic's are as close to a large scale PC monitor as you can get without buying a very expensive 30" IPS PC monitor that will be limited to being used on a PC pretty much only etc.

so in short

S-PVA pros
better contrast ratio and blacks

S-PVA Cons
input lag
poor pixel response speed in comparison to IPS-Pro
poor black uniformity in many cases making the better blacks worse in some cases, larger sized panels tend exhibit this much more than smaller ones but i did have some mild flash lighting in the corners of my 32XBR6

IPS-Pro pros
little to no input lag
very fast pixel response

IPS-Pro cons
Poor black level and therefore overall contrast ratio


they are pretty much equal in color reproduction and range and the IPS-Pro has an edge with viewing angles but not a real significant edge

just FYI i've owned both panel types and used them with my PC so i know them both pretty intimately

thanks for the youtube links, looks good

how is the color red overall with Panasonic?

I've owned a Sony before and I liked the way the default colors looked, more warm tone to it, red tone, is Panasonic close to that?

Samsung i've noticed is very blue in picture tone by default

and LG i've noticed has a yellowish tone even when adjusting color tone to Warm it still comes off too yellow to me

I wish Dell made LCD TVs, i love the way my 2209wa looks on my PS3 with movies, all the colors seem to stand out very well

Another thing I noticed with IPS over VA is text quality is very clear, like frito mentioned about IPS being as close to PC monitors the image onscreen isn't overly sharp like i've noticed with VA its just perfect in the way it displays text and objects on the screen

what your referring to is the color temperature setting it to cool results in bluish whites and warm reddish whites normal is supposed to look as close to white as possible but often can have sort of a yellow hue to it on many TV's

I've got warm tuned on my 37S1 to my liking via adjusting the white balance of it in my service menu but default is ok maybe too red or brownish to me but everyone is different mines closer to 6500k as it should be

I bought a colorimeter and set the xxLh30 to 6500k but the image comes off too yellow, the warm temperature preset is far too yellow which is strange because my Sony KDL 32L4000 6500k actually looks more warm red than warm yellow.

there's no way to change the color space on TVs as far as I know, somebody said unless I knew magic, seems for most TVs can only adjust white balance greyscale and little of tint but no drastic change to the shape of the triangle on the CIE diagram.

God of War 3 demo on PS3, on the Dell 2209wa, Kratos blades have a strong redish tone that stand out and no matter what I do on the LG xxLH30 i can't get it to match (the TV is great other than the bothersome yellow which might only be this particular set?).

I'm wondering if its the difference in IPS technology and the E-IPS the Dell uses is closer related to IPS Alpha which Panasonic uses with the vertical IPS pixel structure?

pretty sure that sort of stuff has little to do with the panel type and is mostly controlled/created by the TV's main board controls

here's an actual picture of someones IPS-Pro panasonic LCD up close

I have abother interesting media to show. I used my LZ800 as a respond to Wip3ou7 on youtube during last summer.

Any buzzing as I have reported Mr. Deep ?

Well I got the L32S1 and it's fantastic. Mass Effect 2 looks great, I give this TV 2 thumbs up for use as a PC gaming monitor. Blacks and viewing angles could be better but I am coming from a 24" TN monitor so it is an impressive step up for me. I sit about 2 feet away from the monitor when gaming and its perfect. Well worth the $430 I paid for it.

Why can't the view angels be this good??

close but you have to be in a sweet spot

Well I've noticed something interesting the past week or two. For a display that was readily available for purchase at around $400 is now being sold for $510+.
Someone has been talking.

TN usually do not have the horizontal break in between pixels, you can confirm its a TN easily by looking at its viewing angles, horizontal may hold its color but I've never seen a TN hold colors with vertical angles they just go to crap quickly

really cheap TN panels like the one in my acer netbook invert colors at any off angle hehe

they are compared to a TN monitor i've got my 37S1 inbetween 2 TN PC monitor and if i go stand off to the side it looks just like that video does

the slight shifts in contrast from left to right on our panels is normal and you can never get rid of it on an LCD

blacks show it more than anything of course and that holds true once again for any LCD

its one of the reasons why i say plasma is the way to go for main TV's in a house under most circumstances. unless you plan on always sitting in an LCD's sweet spot they all look worse from off angles its just not as apparent on IPS and VA display's as it is on TN panels because they keep semi accurate colors at off angles and usually all that happens is the contrast goes down and blacks turn lighter. VA panels also get a color hue to the blacks at off angles IPS just turn lighter.

i actually made a custom picture mode for dark room viewing that is very dim but give you the best blacks possible on these TV's because i was annoyed by the really light blacks when i was watching TV in bed at night


of you wanna give it a try for dark room viewing
custom mode
backlight 0!!!
contrast 90
brightness 49
color 50
tint +4
sharpness 0
color temp warm
A.I. BS off
motion focus on (i'm watching TV or movies in these settings)

this is extremely dim but if your in a room with no lights on at night its plenty bright to see all detail and the blacks will actually look very black

in the daytime and with my light on in my room more normal picture settings look fine to me because the blacks look better when you got more light in a room due to the bias it gives. situation normal for LCD's TBH

I did a similat video against a PVA panel.



May be interesting for some people.

Well I got my L32S1 yesterday. Great TV, I'm very pleased with it. Playing games feels just like playing on a CRT and the motion resolution is very good as well.

I do notice the sound is muffled, but that's obviously because the speakers fire directly into the surface of my stand. Overall, it's not that bad, and it's the same as any comparable TV.

My wife says she misses the LG and called me 'delusional' because she didn't notice a difference other than that the Panasonic didn't look as "crisp" and "colorful." She also misses the LG's quick radial menu and it's little stylish LED bulge thing. I fixed the settings and she hasn't complained since (I think it's starting to grow on her).

I don't notice any buzzing as described by Ice Cold.

Bottom line, if you're going to be doing any gaming at all, this TV is a must have. I couldn't even get my worst games to have bothersome or noticeable blur under the worst conditions; regular TV and movies look great as well.

This TV is selling out (I got mine from walmart.com and they have since ran out) so buy it quick if you want it.

Yeah I am glad I jumped on this a week ago. At first I was slightly bummed I missed out on the $380 Amazon deal. Found it at electronics expo for $434.99 shipped. Now it's $490.99 shipped! I still think it would be worth it at that price however, I'm liking it more and more with some tweaking. Played some Wolfenstein today, looks excellent. I also do not notice any buzzing. My unit was produced in Sept. 2009.

The Muffled sound can be fixed by elevating the L32s1 a little I just placed it on top of my TIVO, And now theres more space for the down firing speakers for the sound to come out. After my 18 hour Burn in. the buzzing sound is gone, but it was never something you could hear unless your ear was up against the back panel.

I personally notice, much better over all motion and movement.

And on a side note I learned my Dell Studio 17 Laptop Display made by LG is also an IPS display. I did the Pixel structure test photo. I always knew it was RGB LED back lit, but I never knew about IPS and its benefits until I found this forum and was so disappointed with Blur and Gaming on my Samsung 32 inch.

I never thought about raising it up, that's a good idea. I though of maybe attaching a slice of curved sheet metal behind each speaker, so it would kind of cup the sound and throw it out towards the viewers.

This TV is what I expected to get when I made the big change from CRT to LCD. It was a big purchase for me, and I was really disheartened when I got my Samsung home and couldn't even play games on it because it was so blurry, then th LG; same problem. I'm just glad I finally found this one.

I noticed that there was a strange connector in the back under a hidden panel, does anyone know what this is for?

Does this TV support 480p or 1080i via component? I'm just wondering because I hooked my PS2 up via component and set my game to output in 1080i, but when I pressed the info button on the Panasonic remote it still said 480i. I then tried setting the in-game option to 480p and I still got the 480i readout on the TV.

Did you change the settings in the PS2 menu (where you can adjust time and such)?

edit:
I may be thinking of something else. Give me a sec and I'll test with mine.

edit 2:
I tossed in God of War II and changed to progressive output in-game. I was able to display and verify a 480p signal.

That's odd. I was using Gran Turismo 4 and it wouldn't work. I already switched my settings on my PS2 to output in Y cr/pb. I'll have to mess around some more and see what's going on. Does it matter what I label the input on the TV?

Edit: I did some more research and found out it's my PS2 not the TV. I have an early version PS2 (ancient and fat), and I don't think it supports progressive output.

Hey guys, a friend of mine is purchasing this TV this weekend and I was hoping someone could point me in the right direction as far as audio connections (I only use hdmi and have NO experience with optical, dig coax, analog, etc).

Basically, she has an older model Marantz AVR with no HDMI capability...it's currently hooked up via analog to a HTIB satellite speaker setup (5 channel). She also runs a DVD player and Tivo box through the AVR. Since the Panny has no analog outputs, what is going to be the best way to go here?

Here's a link to the AVR: http://us.marantz.com/Products/2090.asp#

Thanks in advance!

Well as long as she's not planning on using the TV's built in tuner there is no reason to route audio through the TV or hook up its optical audio out the receiver.

just connect the audio outputs from each device directly to the receiver, this is most likely how its currently connected anyways

if you were to route the sound through the TV you will loose surround sound because TV's automatically downmix DD 5.1 to DD 2.0 and often times completely kill DTS signals but some TV's will pass them through untouched.

I've never played with the audio in/out on my 37S1 because i have my cable box and PC connected to my surround receiver directly

Just received the TV yesterday, and damn it's big.

The viewing angles were so-so from the side but when you look at it from a higher viewer you get some purple banding. I personally thought it'd be a bit better.

Picture quality of SD cable was ok, not as good as the plasma.

One of the real weak points IMO, was the blacks. I used some settings from the TC-L37S1 thread and the colors were good, but it kind of crushed the blacks but it seemed no matter what I did, blacks couldn't get deep enough or they would be a dark purple/greyish(or maybe it's just my viewing environment, who knows?).

Although I knew that's how they would be when buying it, I'm suprised that my 5 year old plasma(EDTV) still has better picture quality and blacks than a modern LCD.

Overall though, I'm pretty happy as long as the TV is good for gaming.

Has anyone noticed a brightness/contrast shift when using this display? I tried using this year's 37" 720p model and even with the AI function (and all other image "enhancers") off I still noticed it. As an example, I had a rather vivid image as my desktop:

http://interfacelift.com/wallpaper_b...rspective.html

and whenever I clicked on the start button, the image brightness would shift. It was subtle but enough to catch my attention. I had other tv's and monitors on hand to test against and none of them exhibited this trait. It could also be related to the power supply but I'm not sure. Just wondering if this issue was only on the 720p sets or on all of them.
