Official Panasonic GT20/25 Owner's Thread! - Page 73

You might be sitting too close and see can see more pixelation. But if it's white noise flashing in spots at random, check the cable or reseat the input connection. Also, check the game system's resolution setting for good measure.

As for the IR, play with the pixel orbiter settings in the TV menu. Also, you could always try using a snowy signal instead of the scrolling bar, it might remove IR faster.

You mentioned a G25 in your orginal post. Do you have that model or the GT25 ?

I have the G25. Honestly the only REAL bad IR was the total zombies killed counter from dead rising 2. And that was when I found some settings that bumped my conntrast and sharpness to around 80+. I've noticed I am getting the worst IR recently. When i have been playing in custom or THX mode, with the orbiter (Anti Image retention) set to every minute. But before when i FIRST got the set, I was playing in GAME mode and never had an issue (Of course I was playing mass effect 2 and Gran Turismo 5 TO DEATH). And in GAME mode I can't mess with the settings for the orbiter. Is it a constant effect on GAME mode? And its tough to find a decent set-up, the manuel says use GAME mode for video games. But the contrast on the default is 100. And if I turn it down that screen gets DARK, and even with the in-game gamma turned to max its still pretty freakin dark. So question, how does the pixel orbiter function in GAME mode since I can't change it. And anyone have good picture settings for playing a PS3? Thanks ALOT guys you are helping me realize my TV is just fine LoL.

Pretty similar tvs g25 and gt25 with the exception of 3d. You're welcome to hang out here but there is also a dedicated g20/g25 thread. Probably not quite as active as this one but some good info there. Fellow veteran here, 23 years Air Force and Air National Guard. Appreciate your dedication and sacrifice !!!

Not sure on the G25 but for GT25 you dont need to use Game mode at all, you could use custom or THX. Again search the G25 thread for some good game settings. Sure someone there can point you to some better settings for gaming.

I usually use the game mode for most of my games.

I have been over to the G25 thread and gotten no replys LoL, and from what I am reading the Plasmas seem to be fairly similar. And no thanks needed, I enjoy my work. But THANK YOU for you decade's of service. Lower enlisted are nothing with senior NCO's to provide purpose and direction.

Most appreciated My calibrator said the GT25 was very similar to the G25 so that is confirmation for you. You might try a calibration disc to get the picture dialed in more to your liking.

Yeah the only difference is should be the 3D, everything else should be exactly the same or close enough for normal people not to tell the difference.

The you can get 1 of 3 HD calibration discs for around $20-30. Spears & Munsil or DVE work well. There is another one that works fairly well from Disney, but I don't think you want Goofy telling you to change the TV settings while in the barracks, haha.

Run through the calibration settings and see if the contrast/brightness settings help with IR.

Another thing you might try is to upgrade the firmware if you haven't done that. It might improve the anti-IR controls. I recently bought my GT25 but the manufacture date was Aug 2010 so there was an update available.

Also, it might be that you have played that game so much that those phosphors more easily show IR/Kills. Try playing another game that has a different static image and see how much IR that displays, if it doesn't show as much I might take a break from zombie killing.

So you might have read a while back, my Panasonic G25 has a buzz on bright images. I do love the TV, but the buzz is killing me.

I called a service tech in, an he admittedly heard the buzzing. He said he could replace the board inside, but did not recommend it, and i should just live with it.

Well i tried to live with it.

Anyhow...i went to the store i purchased it from, and they said they will swap it out for me. Just bring it in. I have to opportunity to swap it for something new, or the same model.

What you think i should do? Get another G25, or is there something else you recommend?

Any models that you think i should look at?



Thanks

I've been tinkering with my settings, not sure I'm ready to dive into the SM, but I am curious, if someone could help me understand the meaning of the cut and drive values? For example how would offsetting RDrv by -25 or BCut by +8 affect the image? And do these have any connection at all to the W/B high and low settings for R and B in the custom picture mode?

Thanks,
Matt

Wow. Just turned on my TV and it's showing a lot of grain that I haven't seen before! I noticed immediately when I turned it on and it's been over an hour now and it's very noticeable! WTF?!

Did it revert to standard picture mode ?

Sorry, I don't know what you mean? I'm watching a hockey game in HD on some custom settings I found here. But, like I said, I haven't seen this kind of grain before.

Cheers.

Its most likely the feed then. I was asking if your settings reverted to standard mode accidently it happened to me a couple of times. Do other channels show the same grain on just that one ?

Well, I tried a blu-ray title and the grain doesn't appear to be there. Maybe it just the source, as I'm seeing it as I flip through some other channels. Strange that I haven't seen it before, since I've had the unit for nearly a month. It's especially bothersome while watching a hockey game, it appears as though someone's put a really thin sheet over the screen.

I'll definitely be keeping my eye out for it though.

Thanks for the input.

G.

Not sure I have been watching Hockey on Versus all night havent noticed it. And you absolutely sure you are in custom mode and your settings are the same ? Check cable connections etc ?

I live right across the street from the CBC here in Montreal and I'm using a wired antenna which usually results in a signal strength greater than 80%. Maybe it's the storm comin' in. I don't know.

Enjoy the game!

Cheers.

How can I set a screensaver or some way to power the TV off after inactivity? I fell asleep with the XBOX logo on the screen for about 5 hours last night.

There is a setting under ECO/energy saving menu option that will turn the TV off after 3 hours of inactivity (i.e. no remote or TV button is pushed). The time is not configurable, it is an on/off setting. Also, the default for no signal turn off is 10 minutes, but obviously that doesn't help in your case.

Really you should look for an XBox settings to go to some kind of screensaver if no input is received. Most devices have something like this. I know the Wii will go to a very dim screen if you leave the remote along long enough for it to turn off (something like 10 minutes, not sure). I don't have an X though so I don't know about that.

On 3/14/2011, I entered the world of HDTV, plasmas, large screens, and flat screens all-at-the-same-time by placing an order with Amazon for the P50GT25 for under $1K to replace my 32/36" CRT (mono). [I'll wait ... til you get up off the floor or reattach your buttocks, whichever applies.]

I am a techie but in computers, not in this area (yet). I am no audiophile or videophile, but I do like movies (when I can find time). I may sound like a baby boomer or older, but I'm just a late adopter here ... I mean, I never say "my bad" and definitely not "I know, right", but I also never say "gosh, that's swell" either ... I grew up with "gnarly" and "radical" and "Like, Oh My God!" Anyway, the CRT just wouldn't die, new baby, less than a year in my house, and the funds don't grow on trees ... at least not in the proper form.

I need some help and just ask that folks define their HDTV-specific terms (e.g., resolution, I understand). I have been reading at this site and elsewhere for a while, but attention span is short with the kid and this is a lot to take in (I've had to write this much in stages). I also couldn't find this thread initially because I searched for "GT25" and this doesn't come up.

Anyway, my concerns are these:

1) Clicking ... noticed a little last week, but a lot in the last 48 hrs ... when off the TV randomly clicks loudly, like someone turned it on ... but no one's around and the red light doesn't come on ... then it clicks again shortly thereafter as if it was turned off (but it was never on). Still not every few minutes ... more like every few hours if I'm around it when off. This is the thing that drove me to create an account today ... everything else I've been living with and had no time to address.

2a) Motion blur: Honestly, the TV is mostly used for my wife's Univision soap operas (I'll watch if I'm in the same room). Coming from a CRT, the skin blemish detail is great (I never previously notice that actress's makeup-covered mole THERE), but when the camera pans around or there is a lot of action, the image gets "sticky" and boxy (that's pixelation?) and has to obviously redraw the fast moving areas. This is not smooth.

2b) Also, I saw "Law Abiding Citizen" via FiOS-EPIX and in the scene when the mayor lectures Jamie Foxx alone, the camera circles the pair and it looks like there are things twisting/turning in the background dark shadows but I think there was nothing there (is that the "floating blacks" I've only read about?).

I expected better from modern HDTV ... and this particular unit based on reviews.

3) Buzzing: I've read this a lot. When there's a lot of white and it's quiet enough, it buzzes audibly. I had seen some Amazon thread where someone got Panasonic to fix it, so I'm thinking to look that up.

QUESTIONS to my fellow (and much more experienced) owners:

Anyone know what that clicking is? Or had it happen? I suspect power supply, but it's been fine (as far as I know) since delivery 3/17/11. Admittedly, I only have things on a power strip ... I'm still researching that one.

Can these image problems be improved via settings? I keep it on THX (read that's the best). Viewing distance is 9-15ft. HDMI from HD-DVR is currently Monster for XBOX (which is going back to Target when I get a lower cost one from Amazon).

I also have a SquareTrade warranty. Given all this data, what are my options at this point?

What else technical does anyone need to know to help me out? Thanks!

I got my gt25 today but the screen was broken; so I refused it. I bought it from
amazon warehouse deals at a super bargain price. Amazon doesn't replace used TVs;
but will give full refund. It sucks cause the gt25 right now is $300 more than what I
first bought it. I don't understand how can the price changed so drastically.
I'm very disappointed with the outcome.

The power supply does make a loud click when the TV is turned on or off. You will hear the same click if you plug in or unplug the TV. I imagine it would again make the same noise if, say, the power strip it was plugged into was in turn unplugged, switched off, or lost power. Does the outlet and power strip it's connected to always have power?


You are seeing motion and compression artifacts that are in the source itself - this is not the fault of your TV. Cable, satellite, and over the air HDTV is typically heavily compressed (compression is the process of using computer encoding to make the show require less bandwidth to deliver - a lot of the original video data is lost in this process, but without it HDTV costs would be enormous), and what you are describing is pretty much the norm for HDTV - great detail in relatively still scenes, a good deal of blockiness in high-action scenes. This will vary not just from channel to channel, but from show to show. It is dependent on the hardware that the show was shot on, how it was produced and processed, how the studio delivered it to the TV channel, and how your TV provider processes and delivers the channel itself.

If you want to see the true potential of your TV, you'll need to get a Blu-ray player and a good Blu-ray movie.


If you can hear it while watching a show or movie, with the volume set at a normal level, I would contact Panasonic. Mine buzzes too but the only time I've ever heard it was when I turned off the computer, the Wii, and the ceiling fan, muted the audio, and specifically listened for it.

Awesome! I know compression and loss of info, but not that there's so much of it on the signal from TV providers and all those other dependencies; that's a relief actually. Yeah, working on the plan for the BluRay and have 1 disc on the shelf waiting for that day (Avatar, of course). And I think my buzzing is louder than yours because I can really hear it if the ad (it's usually an ad) is white enough and the volume is low enough (trying not to wake the family upstairs).

But the biggest and still open issue is that clicking. In fact, it just did it again a few minutes ago and I can hear it from the next room. My wife even reported it clicking WHILE she was watching the TV tonight (that's a first); but she reported no pause or other visible change to what she was watching.


That makes sense and as far as I can tell it always has power (see also my metering info below). No other component on the strip appears to be affected (fios box, Wii, DVD).

And it always seems to click twice when I hear it: click, medium pause, click (almost like on, wait, off). But the power appears to be continuous. I even put a KillAWatt on it, then later heard it click once from the other room, ran to the meter, watched the voltage remain constant (124V I think), and heard the TV click again while I was standing there (with zero change in voltage).

Earlier today, I moved the TV plug to another open outlet on the strip. Happened again later.

This is a weird one and getting more concerning. Any other ideas out there (mattydr or anyone else)? Anything else I should test for? Thanks again for the quick reply!

I think I would call Panasonic about he clicking noise, thats a new one that I have heard. Everything else seems pretty normal. You said buzzing happens more on white screens which is normal too. Mine use to buzz real loud and after awhile it calmed down to where I have to be behind the tv to hear it.

A great TV will show all the defects of a poor source. If you can try a bluray on this TV and be prepared to be amazed.

I'd say the clicking is not normal. Only time I hear it is when I turn the tv on and off.

Agreed, clicking is audible when powering the TV on/off but shouldn't be heard during normal viewing.

@WiiGame - Also, I don't know if you have a Wii component cable but do yourself a favor and buy one. Monoprice has one they make for less than $5.

Mine makes some intermittent quiet click noise both powered down and when its on, not the same or as loud as when its turning on or off. It's almost like a quiet static "pop", kinda sounds like if I had just moved it and it was "settling". Weird for sure but doesn't bother me much.

Like in networking, you're only as fast as your slowest point. Same applies to HDTV from cable/SAT. The universal motto: "crap in, crap out" applies.

I wonder, do you hear it from the front of the screen or the back?

Its really hard to say, it happens so sporadically and faintly, whenever I hear it I'm sitting on the couch about 8' away. For a while I suspected it was an HDMI audio issue causing pops, but it definitely still happens when the tv is powered off.

I should probably also mention that I now have it hooked up to a Tripp Lite LC1200 1200W Line Conditioner and it has had no effect on the pops, before or after.
