Understanding the Issue

Pixelation (squares) observed on the screen represent packets of data which have not been received or were lost in transmission due to a poor connection. This is an indicator of a poor signal which can be caused by a variety of issues including damaged coaxial cables, loose connections, faulty splitters and more.

Solution 4: Bypass the Splitter

  1. Unplug the power to your Digital Box
  2. Locate any cable splitters or extensions that are on the line by following the coaxial cable from the back of your Digital Box  to the cable outlet on the wall
  3. Bypass the splitter by connecting a coaxial cable from the rear of the Digital Box (at the RF IN or CABLE IN port) directly to the cable outlet at the wall
  4. Reconnect the coaxial connection on both ends
  5. You may be required to replace the splitter if your picture quality improves after bypassing the cable splitter. (You can obtain a splitter from one of our Shaw retail locations)

 

Please Note: please be advised that if a phone modem is connected to the same splitter, sharing the same cable outlet, you may lose your dial tone if you remove the main cable connection at the wall. You will want to avoid disconnecting the cable connection at the wall if this is the case. Only attempt to remove the cable running from the back of the Digital Box and where it just enters the splitter to prevent your phone modem from going offline. This is also the case with an internet modem at the same outlet; your internet connection will be offline if you disconnect the shared cable connection at that particular outlet

Solution 5: Additional Notes and Testing

  • Connections with extended coaxial cable lengths can experience poor signal issues. This is because the longer the cable is, the more attenuation of the signal there will be. This means that the signal becomes weaker the longer the coaxial cable connection is. Attempt to replace the coaxial connection with a shorter line if you feel yours may currently be longer than required


  • Check any additional TVs connected to a Digital Box in the home; if you observe the pixelation issue on all of your TVs in the home, there may be damage to your main cable connection or may indicate an area issue
