What is square?

The squares on the screen (Pixelation) reflect data packets that were not received or were dropped in transmission because of a bad connection. This is a sign that the signal is poor.

  • Your TV box (RF IN or CABLE IN) needs a power cable reattached.

  • Even if the picture quality has improved, you can still buy a new splitter from Shaw if you wish to keep using it.

What Are the Causes of TV Color Issues?

Color Setting:

In many cases, poor picture settings are responsible for color issues on all TVs. Fortunately, users only have to re-calibrate their TV’s color settings in this situation. Deactivate your TV’s color setting until you can see just black-and-white images on your screen. Increase depth of black through enhancing contrast and dimming the brightness to achieve a true black instead of a gray.

To remove the halo surrounding lines and letters, increase sharpness to its maximum and then decrease it to its minimum. When possible, use DVDs’ built-in color calibration features to help you adjust your TV’s settings.

LCD Color Problems:

Liquid crystal displays with flat screens re-align the crystal molecules to produce color. If one pixel in an LCD fails, the screen turns black and is devoid of any color. Dead pixels can be caused by manufacturing errors or blown transistors.

Because of fast display movement, such as in video games, colors can appear fuzzy. We know this phenomenon as “ghosting.” It may cause incorrect resolution settings for dull, blurry. A Blu-ray player produces a resolution of 1080p, thus we should adjust the TV to this resolution rather than a 720p or 480p lower resolution.

CRT Color Problem:

Traditional, boxy televisions, known as cathode ray tubes, or CRTs, produce a picture by displaying red, green, and blue primary colors in a controlled way. One major display color–red, green, or blue–can dominate the others because of poor connectivity to external display sources or a malfunction in the TV’s chroma decoder.

Color broadcasts that are completely colorless or black and white show a weak signal, a faulty chroma chip or chroma chip connections, or a faulty color oscillator. These flaws can also result in some hues being missing while others remain intact. A failed cathode ray tube can cause the color to fade intermittently.

Additional Tips For Troubleshooting:

There are a few things you can try if the above methods have failed:

If the image quality is poor just when watching recorded shows, the internal hard disc may fail and will need to be replaced. Is there anything changed in the house? During the process of making the change, a connection may have been accidentally broken.

You can fix the primary splitter as a last resort:

  • The main house feed is here which is also known as the ground block. The primary feed and the breakout/splitter with cables leading to your wall outlets will be visible.
  • Unplug the coaxial cables one at a time until the TV image stops moving to figure out which one belongs to your TV outlet. Your TV is fed through this coaxial cable.
  • Disconnect the splitter and attach that coaxial wire to the main house feed directly.
  • Check to see if the image quality on your television has improved. If this has happened, your main splitter could be the source of the problem.
  • To reconnect the cables, reattach the splitter.

Please keep in mind that this method will not work with all types of whole-house PVRs. Remove the splitter and you’ll lose cable access to everything else in your home.
