Topic: Turn on Unknown LCD via IR (Read 64 times) previous topic - next topic



I happen to have built-in LCD inside bathrooms mirror. It has an IR receiver but no physical buttons so I am unable to turn it on.

I was hoping to build IR transmitter with Arduino (which I did) but then it turned out that there are thousands of different codes and signals for each TV.

Now, how one would turn on an Unknown, unlabeled LCD via IR? I know that 'Telus Optik' remotes have such ability where you press and hold a button until TV reacts - so there are some scan abilities.

Any suggestions?
