View Full Version : Dead / Stuck Pixels - Only on 1 Channel?
Buff-Daddy 07-25-08, 03:17 AM I have had a Panasonic TH-50PZ77U for about 6 months now. I ran the break in DVD for about 6 days and everythig has been great. Last night I was flipping channels and there was a grouping (less than dime sized) of dead/stuck pixels on MSNBC. I flipped channels all night and they would only show up on MSNBC, but they were there every time and did not go away regardless of how long I watched.
Anyone?
dssturbo1 07-25-08, 05:00 AM dont watch msnbc.

No, don't bother getting a tech. I saw the very same thing on MSNBC. At first, I noticed it yesterday on my older Sony plasma and figured it was finally crapping out on me. But then I saw it in the very same spot on my new Pioneer plasma. And only on MSNBC. It's obvious that whatever it is, it's in the signal, not the TV.
If Chris Matthews weren't reason enough to stop watching that network, this finally is! :rolleyes:
gsaoline 07-25-08, 04:58 PM I have a 6 month old 32 " LG lcd tv...never had a problem and have been very happy with it. Yesterday I noticed a green dot just before the MSNBC logo at the bottom of the screen. It appears only on this channel and have been wondering what to do about it. I did a google search of "dead pixel on one channel only" and found this post on this forum. I registered with this forum so I could post this. I'm glad to have found this thread and see that it appears to be a problem with MSNBC and not my TV. I never noticed this before yesterday and I'm sure it wasn't there before.

It's not your plasma TV, it's MSNBC; I have the same on my TV (LCD) and only on that single channel too.
Your plasma is fine :)
I see that stuck "spot" on MSNBC too. And I have a CRT ;)
dirk1843 07-26-08, 01:32 PM Count me in too on a Wal-Mart special Vizio plasma.....(hey my Toshiba RPTV died suddenly, had to have something....LOL)
westa6969 07-28-08, 06:44 AM I saw the same spot that was a whole square block of pixels on CNBC several times last week that gave me a WTF moment but it went away when switching to HD Channels and a few days later it was there again in the same location.
Obviously something to do with the NBC broadcasting process since it does not replicate anywhere else. I'm viewing CNBC right now and it's not there at all but on several different occasions last week. Many new owners need to understand digital channels and SD/HD and HDMI fragility equals periodic hiccups that often have nothing to do with the panel itself.:)
This is on all TV'S only on MSNBC
It could be the camera they are using?
NBC or GE should be advised because I was checking the warranty on my new TV and I was thing of sending it back to the factory, when I saw the same problem on an older Sony Wega
joemama127 07-29-08, 10:41 AM It's the signal....one day I was convinced my 6 month old 77U was dying because I saw a thin horizontal line of white pixels flashing about 3 inches from the top of the picture...switched to a different channel and the same thing!:eek:
Turns out that I was watching the travel channel...and whatever I switched to (can't remember now) was affiliated with and running off the same feed as the travel channel...it was only those two channels.:o
Not the usual "bug," you see in the lower third on most networks. This is a "buger" instead.
It's in the lower third, just to the left of the little NBC peacock in the MSNBC logo. But it never goes away, even when the network brings down the Chyron from the lower third.
This is really weird.
At first I thought it might be the switching station that feeds my citywide feed from the cable provider, Comcast. So I called a friend in-town, who gets his Comcast feed from another office, and it was on his screen, too.
So I phoned a friend halfway across the country who gets his cable from a different provder, Time-Warner. Sure enough, the same buger in the same spot, just to the left of the peacock in the MSNBC logo.
It stays up all the time, even when they fade to black, and in all the network commercials. The only time it goes away is when the local cable system inserts local commercials.
That it's on in all different places in the country, that narrows it down to two sources. This "buger" is either being added somehow when the signal gets handled by the satellite. Or it's leaving NBC's control room this way.
I cannot conceive of a national television network (please, no NBC jokes here) allowing such a glitch to go out over their airwaves. So I've gotta believe it's happening at the satellite stage.
But in either case, I decided to phone NBC in New York today. And they treated me like I was some sort of space alien. It was the most abrupt and dismissive brush-off I've received in my 55 years on earth. Breathtakingly so.
During the brief time I had them on the line, they of course said there is no dot on the screen. (I might as well have told them there was a "buger" on the screen, as it couldn't have elicited any more dismissive of a response.)
But I suspect they're right. There probably isn't a dot on the screen as it leaves NBC. It is unfathomable that a national television network would send out a signal for weeks with a buger on the screen. Even The Buger Channel would put up a bug, not a buger.
So my guess is, the only other place it could be originating is with the satellite uplink, since the downlink signal seems to be the same whether you're watching Comcast in the southeast or Time-Warner in the southwest.
Very strange.
Still, what's most puzzling is that no MSNBC executive -- even one in the engineering department -- isn't noticing it when they watch it on their cable TV at home.
Surely this information has reached them.
Wouldn't you think?
MrMike6by9 07-30-08, 09:54 PM I also spotted "the spot" and started thinking that my soon-to-be-5-year-old GWIII was finally failing but then noticed the pattern that it only appeared with an MSNBC feed or their network commercials. Strange indeed ...
YMMV
bluewaves 07-31-08, 08:29 PM Its MSNBC I had a service call for a customer today just for that reason, so annoying I was like its not stuck on your dvd player or any other channel than it must be that channel.
Nicko256 08-01-08, 04:11 PM Its most likely a set of pixels for some sort of automated picture alignment check. Basically if that set of pixels is at X:Y offset their equipment knows its broadcasting some aspect of their signal correctly.
SunDevilPilot1 08-01-08, 04:27 PM MSNBC told the public what the white dot is during their afternoon broadcast. The answer is the dot is associated with the Olympics, allows the station to determie if they are getting the correct feed.

Nicko256 08-01-08, 04:29 PM MSNBC News answered the pixel question. The set of pixels is an automated check for Olympic coverage. As MSNBC will be broadcasting much of the coverage other MSNBC partners will be able to identify the proper feed selection by detecting the pixel.
manicpop 08-29-08, 09:03 AM it's back, and the olympics are waaay over. so what is it? did shuster lie to us?
it is not there today........they must be doing it (whatever it is) only on certain programs.

Anyone?If it occurs on only one channel, most likely this is "source" related. I have witnessed this phenomenon on both of my displays, a TH-50PX50U and a PRO-150FD.
HD/SD cameras are not infallible... especially those out in the wild (not in studio).
