If your TV is not responding to your remote, this could be due to either an issue with the remote, or the TV's I/R receiver, the following test will help us determine which.
If it is an issue with the remote, this can be resolved simply with a new remote, rather than repairs to the TV.
To begin with, please ensure that you have new batteries in your remote.
1) If you have access to a digital camera that has a screen, or a phone that has a camera, turn it on and direct the remote at the camera's lens. On an iPhone, please use the front-facing camera, the rear camera will not show the light.
2) While looking through the camera, try pressing any of the buttons that are having issues and look for a flash of light. The flash is not visible to the naked eye, and can only be seen through the camera's display.
If the remote is working correctly, there will be a flash of light visible on the display.
If it is not working, there will be no flash of light.
If you see a flash of light and the remote is still not working correctly, check to make sure none of the remote's buttons are stuck.
Replacement remotes for your TV may be available on our website. Alternatively, please contact our Support Team with your TV's model, your invoice, and the results from the above test.
