Follow these steps to connect your new DISH remote to the TV:
Press either the Home button twice or the Menu button once depending on your DISH remote and go to settings.
Now select Remote Control from the on-screen menu.
Next, select the device you want to pair it with.
Click on the Pairing Wizard option from the menu, and search for the brand of your TV in the on-screen menu.
Next, follow the on-screen instructions to test a series of device codes for your device.
To check if the code is right use either the Volume or Power buttons on the DISH remote to see if it is working.
Once you find the right code, press Finish. If not, try out the next available code via the same process.
