I like my Rii K06 keyboard. I have one small problem I'm hoping for some help with. The IR remote will turn off my TV but won't turn it on. EDIT: FIXED IT (lemmy.world)

Basically, the title. It's an old Toshiba flat screen. I successfully "taught" the keyboard the power button code. The keyboard will turn the TV off, but not on. The power button on the remote is just one button, a toggle, like normal. Of course, the remote will turn the TV on and off, by pressing that one button. I can't imagine what is wrong, it must be the same code for on and off, right? I mean, the things aren't that complicated.

Thank you.

EDIT: It works if I program a button on the keyboard other than the power button. So I programmed button "C1" as the power button and for whatever reason, that button will turn the TV on and off. Weird. It's the keyboard treating the power button differently.

I have that same remote/keyboard and love it.

Had the same problem and similar solution with some LED candles since I kept losing the little mini remote. I taught C1 from the power button on the candles' mini remote. It would turn them on, but not off. So I had to make C2 the "off" command by learning it separately.

I have absolutely no frigging clue why that works the way it does. You'd think it would be the same signal either way, but something is definitely different.

So far, that's the only device that acts like that. I programmed the power and directional buttons to control my Eufy robo vac, and those work as expected. The buttons above C1 and C2 work to toggle power (left button) and cycle thermostat settings (right button) on my electric fireplace correctly as well.

Having dabbled with remote codes I can only assume that the remote sends a different, albeit common, signal. My Chromecast remote for example does not send (via Bluetooth) a traditional signal code for power, but a signal name that only is recognised by some devices.

Why does it look like you're about to launch an ion torpedo in the cooling vent of the Death Star?

[–] call_me_xale@lemmy.zip 5 points 2 days ago

Ackshually a proton torpedo would be more appropriate for that application. Duhhh

@DarrinBrunner That might have something to do with your TV’s standby status and settings. For example, “Wake-on-LAN” is not always available, nor are some network interfaces, including BT.

[–] bunnyBoy@pawb.social 3 points 2 days ago

Have you looked up your remote to check if the power on and power off codes are the same? I would think that they would be, but if it only works one way then it may very well be different. Could also use a little IR receiver and an arduino to check it for yourself

I need this.

Some manufacturers made all sorts of different codes for instructions between various models of tv and remote. That includes some different TVs only sharing an 'on' or 'off' code and not the other.

It's why many 'universal' remotes will tell you in the instructions to keep trying different numbers for the manufacturer until all features work. So... you'll have to do that. Try all Toshiba TV codes that remote knows. If none of them support all features, hopefully you can tweak button by button!

I believe this is the answer. If you can turn off the TV but you can't turn it back on then you're probably just using the wrong code.
