TV signal seems to "crack" with pixel distortion.

picture freeze & pixels messing up, sounds like a signal problem. Try connecting a DVD player & see how that source performs.

Could you provide more information? What do you mean when you say, "closing?" Do you mean there is a black band around the picture? If so that means the original picture is recorded at a lower pixel density than your TV will display.
In the past most TV program signals provided a picture dimensions (in computer standards) very roughly 600 pixels wide by 400 pixels tall. What this means is that a picture of that pixel size will display as a small, squarish image slightly wider than it is tall on a (now) standard 1080p LCD television--which produces an image 1920 pixels wide by 1080 pixels high.
That would be nearly unwatchable (picture too small) except for the fact that most TVs compensate for the relatively small size of "standard definition TV (SD TV, as opposed to HDTV) by enlarging the image so that the top and bottom edges of the picture touch the top and bottom of the TV screen. This will leave black bands on either side of the picture. Some LCD TVs will automatically stretch BOTH dimensions of the image, which yields a distorted, "sqaushed" image.
All my comments above apply to both standard LCD and 3D-LCD TVs, by the way.

Hello

Make sure TV is on the correct channel or input. Check the cables for correct routing from TV to any other devices. Check cables to ensure they are tight and secure.

An analog signal converted to high defintion resolution will cause lines, blurriness or fuzziness in the picture. Change the resolution to a lower or native setting using the media device (cable box, DVD,). This may be an issue that requires a service call to cable provider.

A problem on one channel may just be a error on that channel. If using an antenna, it might need to be adjusted in order to ensure good signal strength. For digtal channels, go into TV Menu. Check the DTV signal. Weak signal can cause picture distortion.

If another device is being used such as a cable box, DVD player or VCR switch between devices and test picture. Check routing of cables that are used to control the image. This should be a series of red, white and yellow cables.

If a VCR with a cable box, make sure the VCR and TV are set to the correct channels for video signal to pass through. If problem is still occuring, try another set of cables. bad cables can cause picture distortion.

Bad cables can cause picture distortion as well. Try another set of cables. If picture is better than when using the cables replaced, this was the issue. If cables are not an issue TV may require service.

Tv it is the causes and the problems of the board call tv Tuner signal board it is dying.The tv Tuner signal board it is the board,where the incomming signal cable plug into.U have some mechanical skills?Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

A distorted picture display soon after the Plasma TV is powered on has two indications. First, a picture display of pixels when the TV is powered on is usual prior to signals of video movies are acquired from broadcasting station. The movie from braodcasting station should display without noticeable objects of distractions. For example, the movie displeyed on the TV without obstructions is indication that the problem is from the display set. Alternately, movies with poor capability to display on the set is indication that the media from which motion pictures are acquire from is malfucntioning. For example, a TV connected to cable network or disk network or satellite broadcasted signals with receptive compromises are diagnosable from two areas. First, a clarification from the network station that has setup connectivity of devices. Perhaps a device in the setup is malfucntioning. Second, attempting the adjust the phsical connections that are attached to the TV is capable of resoving the problem. Refer to the user guide for what is default expectation on powering on. Thereafter consul technical experts if required. Good luck

Sounds to me like the digital pixeling that occurs with a weak signal. You have not identified whether this happens on broadcast/antenna TV, cable or satellite service, or a video input such as a DVD. This can be a common problem if you have a weak signal on any of those inputs. In any case, blowing out the dust will not help.

what brand is this tv and what technology (plasma?)
To me this is plasma problem and maybe samsung brand. a posible adjustment can be done.

Please check the image size (pixels x pixels) setting or the resolution (MP). Seems like the camera is shooting in low resolution. Have you used this memory card on a mobile phone or another camera? Format the memory card and try again.

Hi, Pixelating and freezing are symptoms of loss of signal. You need to check all of your connections. Check for water in any connection. Check your satellite signal strength on each satellite and if low or they are all not there you could have a bad LNB but you need to check the LNBs and the multiswitch for poor or bad connections. Also check for any obstructions in the dish view to the sky or for anything that may not have been tightened down on the dish. Snow and ice builtup will cause this problem as well. Good Luck! Let me know what you find.

Hi,

The pixelation is probably caused by MPEG2 compression on the DVD and Virgin media video streams, the blur is probably caused becasue you are displaying a standard definition signal on a high definition TV.

However if a high-def source still has these problems then you may have a faulty TV, your best bet is too hook up a high-def source such as a HD/Blu-ray player or PS3/360 games console.

Should a high-def source look ok, then you may have some look changing the display settings on the TV to try and improve picture sharpness and color balance.

Thanks.
