Pixels are breaking up.

I have had no problems with this TV but today the picture started to break up. It looks like the pixels are not working. It will break up and then be okay for a moment. Then start again. Anyone else know why this happens or have a similar problem?

SOURCE: The color red is starting to flow throughout the picture.

I have fixed a lot of Vizio TVs. You are getting red pixelation. Some people have green pixelation, too. Usually change main board and main connector cord for fix. Check with vizio and see if it is still under warranty. Some parts have a lifetime warranty. If you call support and give them your model number they may be aware of the problem. It is not your inputs or wiring. It is the boards inside the TV. Let me know how it turns out. Good luck, John.

SOURCE: Horizontal (dashed) line across screen

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to for customer service. Good Luck

SOURCE: My HDTV breaks into pixels. How can I prevent this?

I have occasionally faced same pixel problem with xbr5. Connect the RF cable directly to your TV and tune it to same channel to verify if the problem is in TV. Most likely you will get better picture quality.

SOURCE: blue pixels taking over

The light engine has dust in it.
There are a few good TV Techs that are now trying to clean the Light Engine rather than replace it at a $1500 cost. There is hope, but ask the Tech if he does this job first otherwise there is no hope unless you chump out the big bucks.

The picture freezes on my Toshiba TV and the pixels break for chopy pic. Is it an issue with the TV?

If the input signal strength is weak; this might happen. If the main digital processor board of the TV is faulty, this kind of fault can occur too. Contact any service technician to make it confirm.

Picture pixelation

TV manufacturers know that a certain percentage of TV's will end up with dead pixels. I believe there is an app called UDPixel that can fix dead pixels on monitors and TV's. Google it.

Samsung LCD seperated pixels

Though this is evidently a problem within the TV, just try changing the input device to some other like a DVD player and see. Look for any loose contacts in RC jack, cable and socket, as intermittent contacts can bring such funny looking problems, as the TV does not get time to recover from the making/breaking time. If problem persists, I recommend you call in a qualified service technician, as opening the back cover by others is not advisable.

I have a Sony Led Lcd tv and the picture keeps breaking up and I can see pixels and the voice breaks up too. Could it be the aerial cable. We had a new HD aerial installed on the roof.

More than likely. There is no such thing as an HD aerial, there is no difference.
It is a sales description. Like Digital Ready and all that stuff.
The HD is your receiver, not the aerial.

Picture sixe reduced and picture breaks up with converter box

You can change the way the channels can be displayed/viewed by a video setting, consult manual. When pic breaks into pixels and sound goes it's usually a reception problem so you'll have to adjust the antenna facing a direction that makes that channel come in clearly. It helps to experiment with positions and antennas.

Pixel damage

Those small pixels are now damaged not much u can do with it. Some people say you can press on the screen the pixels affected and possiblilty get them to make contact and light back up ( I honestly highly doubt it) If u can live with and not very distracting keep watching it. But if you want to order a replacement, more than likely it will cost more than the TV did when u bought it. If its still under warranty get it replaced if possible.
