Is This An Infra-Red?

Does every remote control of the TV is using infra-red?

Most of them are IR, yes. A few high-end remote manufacturers use Bluetooth, but these are so rare it is very unlikely that yours is. A good way to test is to take a standard phone camera or other cheap camera, look at the front of the remote through it, and press a button on the remote. You should see a purple-ish light blinking.

Only TV without or with lost remote control dont use IR, all others use. :smile:

In older days, some TV remote controls used ultra sonic.
