Looking for Answers about samsung 50" Class 450 Series 720p Plasma HDTV?

I do not understand the question.

Please contact 1 800 SAMSUNG for additional help.

My TV started having the same problem a month ago. First it started with a little bit Red pixel Snow on the right edge of the screen. I was advised by Samsung to update the firmware. The firmware is supposed to adjust the voltage for the screen to take care of this problem. If the firmware update does not work, you need to have Samsung send you a technician to make additional voltage adjustments from the inside. A quick process. My TV after the firmware actually got worse. Instead of the Red Snow, the right side of my screen glowed red. The technician quickly adjusted the internal voltage and everything is fine now. Note: Other brands of Plasma TVs also have the same issue. It is not limited to Samsung Models.

I beleive that there is a firmware update that you can download in the Support section of the pge for your TV. Be sureto downloadthe instruction manual as well. It says that it addresses "red spot" and "spark" issues, so it could help. Just be careful updating firmware, mistakes can be expensive.

The PC50C450 does not have a swivel base

Unfortunately it does not.

No, it does not.

Yes all you need to do is have a digital antenna hooked up to it. TV will automaticlly tune in stations.

Yes, this T.V. does have a built in digital tuner.

Absolutely! You will need a wall mount with a Vesa bracket size of 400mm x 400mm.

Yes, it has the appropriate holes and instructions to mount it on a wall.

I have had my 4 series plasma for about 3 months now, and I am not aware of any light under the screen. I'm pretty sure there isn't one though.

I'm assuming you're referring to the Red Bar at the bottom of the screen frame for the PN50C450. That lights up slightly on it's own but you don't have the option to "turn it on/off".

I hope that answers your question.

With the information you have provided, it would be best if you navigate to the Samsung Support Page and either click on the link to speak with a Live Rep directly under the “Contact Support” section in the middle of the page or request service for your device under the “Schedule a Repair” section.

The PN50C450 does not support direct internet connection through apps. You can get to Netflix if you have a Wii, XBOX360, PS3 or any other device (most current Blu-ray players) that support the Netflix app. You can also connect a laptop or PC to your TV and get Netflix that way as well.

YES the PN50C450 has a built in QAM tuner. All TV's manufactured after 2008 were required to have built in tuners.

I have this TV and use it sometimes with an antenna to get over the air HD channels. The picture is amazing!!

It seems that your TV is in Demo/Store mode. Please follow the link below for more information on how to deactivate demo/store mode.

From the information I have, the C450 will only support 2.1 audio out of the optical audio output when processing a signal from a digital source (HDMI), but will support 5.1 output from a coaxial source (cable).

Please contact 1 800 SAMSUNG for futher assistance. Your TV may need service, but we need to make sure through troubleshooting first.

Unfortunately the PN50C450 does not have connect shareMovie, it only has ConnectShare™ JPEG. I ran into this problem myself thinking that it did (because that's what the website was saying). However after contacting Samsung they said "sorry but NO".

IMOP they need to do a system update and make this part of the offering for the PN50C450.

Yes, when viewing digital channels with the built in digital tuner it does display signal strength. You just have to press the "Info" button on the remote control.

Unfortunately, Samsung can not suggest any specific calibration numbers since every calibration has to be done based on the preferences of the customer performing the low level calibration.
Perhaps other users on this forum may be able to better help you out.

All current generation Samsung TVs are digital cable ready. All of our TVs include a coax ATSC/QAM tuner that handles digital and analogue broadcast signals as well. No external boxes or equipment needed to view your basic cable. Premium service may require additional equipment and fees. Please contact your service provider for details.

-MrSamsung

contact samsung for a new panel. that is the only way it will go away. but it will happen again as the firmware updates will give you a blue screen or red pixels...
