Here's a trick you can try to see if the remote is sending IR or not.

Use a digital camera (or camera on your phone) and point the remote at it, when you press buttons on the remote, you should see a light flashing from the remote on the camera's LCD screen, which you can not see with the naked eye. That's IR. If there is no light flashing, there is not IR output.

I hope this helps!
