Sometimes, not all of our codes work with the TV manufacturer. However, I recommend that you use the following link to help you: https://www.mydish.com/support/products ... to-tvother . Make sure to select the "three-digit remote control code" for more code information.
I have tried it by entering codes as well as trying the up/down buttons. I tried it with the other remote (2nd TV) and at least got the TV to turn off. But the "main" remote won't do anything when I hit the # button to lock the code in so I can try it.
Let's try the scan method and see if the light does not flash after selecting the # button.
Have your TV on during this process. Press hold the TV button until all four mode lights appears then release and press the receiver power button. Now, press the up or down arrow button until the TV turns off once it does then press the # button. Let me know if the TV mode button does not light up. This process may take a few minutes while clicking on the up or down arrow button.
