I`m gonna show you, how to test the working condition of any remote control with the help of a mobile phone`s camera, it`s impossible to test the remote without the help of a device but, doing like this will reveal the working condition of any remote control.
It`s quite simple......
Turn on your mobile phone`s camera and place the remote under it ,the LED of the remote should face the mobile phone`s camera lens..then simply press any key of the remote,if the remote is working,then you should see the illumination(Glow)or(Light) of the LED of the remote control from the mobile phone`s screen as shown in the image...whereas it Can`t be seen with naked eye...so every time you press a key you can see illumination of the remote`s LED.That`s how you`re gonna test it.
Guys i don`t know the logic behind that...so don`t ask !
