Samsung PNXXc450 Owners Thread *NO PRICE TALK* - Page 45

I presume your signal sources (TV broadcast stations) are coming from the two different directions correct?

Here in DFW and my physical location all of my HD signals come from about a 260 degree heading (almost due west of me). So I'm lucky that all I do is point my OTA antenna one direction to receive all ATSC broadcasts (I only use it for weather however).

Sounds like yours are coming from directions, great enough in heading differences, resulting in an "out of view" situation for your antenna. Thus the reason when you point your antenna one way and re-scan for channels it looses the channels from the previous direction your antenna was facing. Overall quite normal and at no fault to the TV tuner.

Cheers

I just got my tv and I have not heard any buzzing at all. Like I said I just got it, this is my 2nd day. So far I am very happy with my choice. I looked at a lot of others and decided on this one because of the price and what I read about it. Hopefully I will not get any buzzing. I am playing around with the colors and there are so many combination's and my "Dynamic" setting works, it gives like an extra boost of color makes everything "pop" and look really bold. I will keep you posted on whether I get a buzzing sound but for now nothing. Did you put the little adapter around the power cord this is supposed to cut down on interference.

I understand what it is you are saying. I'd just prefer 1080P. I can see the pixels on my set now. PC input isn't bad but it could be better. If they made the 42 in a 1080P that would be perfect.

Does anyone know what the latest firmware update addresses for the 42".

Well, sure, it would be. They are increasing their plasmas by one inch; so, you'd be looking at 43" TVs. It's not clear to me, (or I just don't remember), if they'll have a 43" in the 6500 series; no 43" for the 550 series; just the 450 again. I wonder, if anyone thinks there is a good chance, the 43" d450 will be 1366x768p rather than 1024x768p ? Maybe somebody knows for sure; though, it's not exactly a much talked about TV.

Where do I find the info on that?

Ive had my 50c450 for a couple of months now and i gotta say for the money i couldent imagine a much better tv. I was using pendragoon's settings for a while but it seemed slightly dull so i went to standard mode and tweaked from there. I think the TV looks great at these settings so ill post them and would appreciate any feedback if somebody trys the same settings.

Mode - Standard
Cell light 8
contrast 70
brightness 54
sharpness 55
color 47
tint g54/r46
black tone off
dynamic contrast off
gamma +1
flesh tone +1

28

I think the picture with those settings is the best I can get the TV to look.

I hear you. I've had mine about 6 weeks and have loved it once I found a setting I like. Sports and action movies are incredible on plasma , I'm glad my bedroom is big enough for my recliner too. I'm watching this tv a lot.

It's a shame plasma isn't good in bright environments. This tv has really made me think twice about another plasma.

Who knows how to remove floating 'No signal' from the screen? Is there any way to do it? Blank channel for example.

I had a similar experience. I was dead set on getting a 42 inch S2 until I actually saw it at Best Buy. I'm sure it was an S2 that had already tripled it's black level but it just looked horrible. I adjusted it to the settings recommended here but it was no use. The TV didn't even have a "black level". The best was to describe it was a "gray level" and even that wasn't very good. I hope it was just a defective unit as I've not yet decided which plasma to get. I'm probably going to go with the 50C450 since I'm very impressed with how much cleaner Samsung Plasmas seem to be.

Thanks for all your help - Pendragoon - I have been using your settings for a week now on my new 42 and I love the picture.

This weekend is going to be a big ol PS3 fest - cant wait !! I am new to the PS3 and have never played it before.

Ouch. You chose a bad time to start.

Ok.... I gotta ask.... Why ?

The PlayStation system has been a great system to play on. Until now. If your getting it for online gameplay. Your going to hate it. All offline gameplay shouldn't matter. Anyway. To my point. The PlayStation3 system has no been hacked. It's been hacked to the point that it won't be able to be patched anymore. Regardless of what Sony tries to do. It will never be patched. That's a long story. Now, what this means for you? Well, pretty much any game you play online you would be playing against someone with mods. You'd have an unfair advantage. I love my PS3 for Blu Ray for my TV. That's it. Unless you like modding. I wouldn't bother with that system.

Hey there - finally posting about a problem I've had with this set for quite a while: it occasionally TURNS ITSELF OFF.

Seems as if someone pressed the POWER key on the remote - the set just shuts off after the red LED blinks a couple of times.

I've tried a variety of things, including disconnecting all sources except for the DirecTV box. I've also closed all the window blinds, turned off all lights and physically removed the remotes from the room. Still happens!

Today, I thought to apply some gaffer tape to the lower right of the bezel, in order to block all IR from getting to the sensor. I then discovered that you could still use the remote if you pointed it at the little bit of the bezel that serves as a relief from the screen (the inner-lower-right).... this got me to thinking: is it possible that something being DISPLAYED on the screen is generating IR with the proper sequence of flashes such that the TV *thinks* that someone is using the remote????

I put some more tape over that area and verified that I could no longer make the remote control the TV.

I let it run like that a while and did not have any shut-offs. Then I saw that there was an updated firmware (1008) available, so I updated (from 1006). Unfortunately they don't provide release notes, so I've got no way of knowing if they are aware of this symptom... but hey, it's entirely possible that this is addressed in the 1008 release! I've removed the tape for now and will let the set run for the next day or two to see if it turns itself off. I'll post back with an update.

I notice the problem on a variety of programming and times of day (diff light conditions in room). The TV is showing CNBC HD+ a lot of the time, so I see it on that channel the most.

Anyway, sorry for the long-ish post but it's such an odd problem that it's kind of hard to describe. Has anyone else had an issue like this with their PN42C450?

Sounds like the "Grumpy Old Men" syndrome...

Color Temp is set to normal. We seem to have some pretty different results for some reason. I switched to these settings and to my eyes I think the colors pop a lil more but u seem to be getting results to the contrary. I do see better shadow details with these settings as well.

I dont really think u can go wrong with either settings. Your settings look great as well. To each their own and i just recommend that everybody just adjust the settings to the way you like them and you'll be a happy customer with this TV.

As an added sidenote im sitting about 12' from the TV what distance are you at?

OK - here's an update. The 1008 release did not fix the problem, but I've made two (interesting?) observations:

1. I found a particular scene in CNBC's special on Target that tends to trigger the power off event. By replaying that specific 10-second scene (happens to be a bright, mostly white graphic) the TV will turn itself off about 30% of the time. I believe that this is strong evidence in support of the idea that something being displayed on-screen is triggering the issue.

2. I decided to switch the picture settings to "Standard" and enable the eco dimmer & energy saving options. This has the effect of reducing the output of the screen quite a bit; I was previously running in Movie mode with a Cell light level of 9 or 10 (it is now 5 or less). The set has been on for about eight hours now without any issue... perhaps this has resolved the problem? Not an ideal solution, but since this isn't the set I use for movies I can live with it.

Still quite a bizarre issue and I'm surprised that I appear to be alone in experiencing it.

My set randomly turns off. Even on. IDK why though.

lol, at least I'm not alone. FWIW, mine has never turned itself ON - only OFF.

Well mine doesn't turn on or off on it's own but I do notice that every once in a while when I turn it on I notice the picture shaking back and forth slightly.

Is that the pixel shift to prevent burn in? It seems to me that it would do that after it has been on for a while , and if I turn the tv off then back on it stops. It never does it any other time other than when it's initially turned on. This is my first plasma and I don't know if that is normal or not ?

Also I noticed my speaker is blown in the tv , is it replaceable ? I'm still within my return period since it was purchased at BB in December. I would hate to start over and break in another plasma , also mine is very quiet , I'd hate to get a buzzer if I return this one.

Any help with either or both of my issues would be appreciated!

I have my TV hooked up to my receiver (Onkyo TX-SR508) via optical out, and every time I change a channel, I hear a somewhat loud popping noise as the channel changes. Is there a way to disable or prevent this popping noise? It's annoying.

I have my 50 inch hooked up to my denon 1908 via optical and have no popping. While the popping could be an TV issue, It may also be onkyo issue. Just an FYI.

Standard mode looks more like an LCD-type image to me....shadow detail looks better than Movie but there also seems to be an enhanced crispness to the image along with more light output and cooler colors. I agree with Pen about Movie mode having deeper/bolder, richer colors. I also prefer the richer skin tone look on the Warm settings than the pale flesh look on Standard.

I used to have my set on Warm2 because I found Pen's settings with Warm1 were too pink/red and cool, and turned down the G Gain to account for the greenish push. However, I've recently been playing with Warm1 again and seem to like it better than W2 now. I have all white balance colors set at 25, but I turned down the Reds to around 22 ; turned up the G gain to 28 and pushed the tint to G54 and I seem to have found a nice well balanced image to my eyes.

Are there any other significant differences between the C430 and C450 besides one less HDMI and no Touch of Color?
I checked out the Sammy support site and it appears they utilize the same firmware.
I personally prefer the look of the solid black C430 and am thinking of grabbing one instead of the C450... any thoughts as to why I should not do this?
Thanks!
