Learn how to troubleshoot TV issues such as not being able to change channels as a result of IR (infrared) sensor issues. Some Televisions have automatic sensors installed which will adjust the contrast and brightness of your TV automatically depending on the ambient light in your viewing space. To do this, your TV utilizes the same IR sensors that remote controls often use, and this can cause a conflict which will prevent the Shaw Remote from being able to function with the Digital Box.

 

 

Troubleshooting quick fix
Follow these steps to fix the issue of not being able to change channels while the TV is powered on.
 
  1. Power off the TV
  2. Ensure the Digital Box is powered on
  3. Change the channel on the Shaw Remote to 999
  4. Power the TV back on
  5. If the Digital Box was able to successfully tune to channel 999 while the TV was powered off, but still cannot change channels while the TV is powered on this would confirm that an IR conflict is present in your setup.
  6. Use the remote control that came with your television set to find and disable the feature. Depending on your brand of TV, this may be labelled differently. Here is a list of the most common ambient light sensors listed by brand, as well as the steps to disable them.
