Hello all,

I've got a RPi 3 which I use to view YouTube stuff on a TV. Although the
TV automatically switches to the RPi when the latter is switched on, it doesn't switch back when the RPI is shut down.

Question : is anyone know of a program which will release the TV (so it can switch back to whatever it was displaying before, as it happens with my DVR)
?

Rudy Wieser

I've had a similar problem with the pi4 and an hdmi monitor. The monitor
is connected via one of those multi-input automatic switches: it won't
switch away when the pi is shut down - the pi4 needs to be powered down
too. Have you tried powering down your pi? - does it switch then?

Mike,

Thats the name I forgot, HDMI. The RPi 3 is connected to the TV using HDMI.

Have you tried powering down your pi? - does it switch then?

Yep, nope (I just repeated the test to be sure I did). The TV just keeps showing a "no signal" message.

Then there is nothing you can do about the pi, it's turned off. So you
must check if there is a setting on your HDMI switch to make him switch
back when there is no signal on input x. If you don't have a setting for
this behaviour you need a different switch.

:-) There is a moment before its shut down and powered off that its still running. That would be a splendid moment to have the RPi tell the TV that
it should switch its inputs away from the RPi, don't you think ?

So you must check if there is a setting on your HDMI switch

It might be worth trying "vcgencmd display_power 0" at that point,
which I think effectively stops the HDMI output, just in case the TV
happens to treat that differently. I sometimes use that with a monitor
to do something similar. (You could try that out without turning off
the Pi of course, and it's "vcgencmd display_power 1" to get the
picture back.)

Yes, I also thought of such a solution. But :

1) It looks like that shutting- and powering-down the RPi should be "rather effective" in stopping the HDMI output. And when I do I get a "no signal" message on my TV, confirming it.

2) looking at a black screen while trying to figure out if the RPi really
did shut down isn't really a situation I want to find myself in.

Being able to instruct the TV to switch away from the RPi gives the best of both worlds. In doubt I than can have the TV switch back to the RPi and
check if it really shut down.

than that...

Sorry, I was mixing things up with my own setup here. Basically why I
got an HDMI switch although my TV has plenty input is exaxtly the
behaviour I described: whatever I turn on makes the switch go to this
new source, when I turn it off it goes back to what was playing before.
TVs don't do that, (most) switches do and with some switches the
behaviour can even be configured. So I have four HDMI devices all
connected to the switch and one HDMI cable from the switch to the TV.

You forget to mention the part where I, /way/ to often, have to tell poster that what they offer isn't what I specifically asked for in the first post - or worse, offering work-arounds which I already mentioned in that first post and not wanted to use.

... and than try to make it sound as if its all my fault, and sometimes as a result, as with you, bear a (life-long?) grudge.

Kid, I've encountered too many "helpfull" people who just skipped the
question and pretty-much demanded that I should accept their work-arounds as *the* solution. Others who claimed all kinds of things, but could, when pressed for it, not come up with any kind of substanciation, let alone
proof, for any of it.

Its also remarkable (not really) that you make a claim of wrongdoing, but am not supporting that claim in any way. Nothing by anything in this thread, not by linking to any other one*. I know, I know. Putting your mouth where your money is is /dangerous/, as you could be proven wrong (like the last time?). :-)

That would indeed be a way to test if vcgencmd command works.

Although you did not mention it, I take it you picked up on that just disabeling HDMI output doesn't cause my TV to switch back to its previous input. Which means that that vcgencmd doesn't seem to be the sought-for solution (and nullifies the need to test it).

What are you talking about ? A "remote machine" ? This is about my RPi and the TV its connected to, with both being located directly next to each other. Nothing "remote" about that.

Also, I think I made quite clear that I *didn't* want my TV to be turned
off. Just for it to switch to its previous inputs when the RPi is shut down.

As it looks as if we are not quite understanding each other maybe you could explain how your "SSH" suggestion is supposed to work ?

I just asked ChatGPT if it knew an answer, and it did (not that I am
certain if it works):

Yes, it is possible for a Raspberry Pi to send a signal to a TV to
switch the HDMI input before shutting down. This can be done using CEC (Consumer Electronics Control), a feature available through HDMI that
allows devices to communicate with each other and exchange basic control commands.

Here’s how you can do it:

Check if the TV supports CEC: Not all TVs support CEC, and it may be
branded under different names like "Anynet+" (Samsung), "BRAVIA Sync"
(Sony), "Simplink" (LG), etc.

Install CEC tools: On the Raspberry Pi, you can install the cec-utils
package, which includes a tool called cec-client. This tool allows you
to send CEC commands.

bash
Code kopieren
sudo apt-get update
sudo apt-get install cec-utils
Send CEC commands: You can use cec-client to send various commands to
the TV. For example, to instruct the TV to switch to a different HDMI
input, you can use specific CEC commands.

Create a script: You can create a simple script that sends the CEC
command when the Raspberry Pi is about to shut down. For example:

bash
Code kopieren
#!/bin/bash
echo "as" | cec-client -s
The command echo "as" | cec-client -s tells the CEC client to switch the
active HDMI source.

Execute the script on shutdown: To automatically run the script when the Raspberry Pi shuts down, you can add it to the /etc/rc.local file or
create a Systemd service.

Keep in mind that the exact commands and setup may vary depending on
your TV model and the supported CEC functions. It's a good idea to refer
to your TV's manual for specific information about its CEC support.

A partial success. After having installed the cec-client software I was
able to do a scan and switch the TV off (meaning : the TV does respond to
CEC commands).

However, the "as" argument didn't seem to do anything.

I also tried a few "tx" arguments (found on the Web) with the TV (0.0.0.0)
as the target but could not evoke a back-to-tuner-input response either.

Any idea(s) ?

I seem to have a couple of years of experience with myself (duh :-) ), and have noticed that I am /very/ likely to make typos when trying to do that. Even to lauhghable proportions when I'm tired.

But thats not the point.

but then someone suggested you could SSH to the Pi from somewhere else to type the command to re-enable the screen

The one suggesting it was Lawrence. And his whole suggestion was exactly four characters, "SSH?". IOW, not having /any/ of the info you, in the above, have provided (and he still hasn't by the way).

After which I wrote that that would be solving one problem but by it
creating another.

Based on his responses I had to conclude that Lawrence has absolutily no
idea what I'm talking about, so I asked him to explain his solution. Hey, perhaps his SSH solution is different from the one I know, and cannot ever be(come) a problem.

I'm still waiting for that explanation though, as no matter how strongly I indicated I need some he refuses to supply it. All he's posted is a few words which start with "SSH" - without any explanation to them - and a few iterations of "remote machine" - again, without a sliver of explanation of what it is or how its supposed to be used.


So yes, there is a distraction going on, but it isn't the "SSH?" suggestion one itself (it might have worked in quite a few circumstances). Its
Lawrence there verbally dancing around, trying to evade having to say
anything at all. Why ? Only he knows.

... Though my guess is that he doesn't actually know much of anything about it. Just some "big words" he tried to impress me with.

to the pi


so get the ip of the pi, and connect another pc to the same network and
type

ssh pi@the-ip-of-the-pi

provide the password at the prompt.

Now you have ssh()ed to the pi.
You have a terminal session in the pi.

now execute the commands and be done with it

Bj÷rn,

... Though my guess is that he doesn't actually know much of anything
about
it. Just some "big words" he tried to impress me with.

So would I.

But in my particular case that would be a problem.

And I'm not talking about that I would need to keep a 'puter at ready just
to be able to check that the RPi shut down correctly.

Though the problem I referred to would make moot of that.

Than again, if someone would have realized (or just asked for!) the problem
I referred to (s)he might have been able to suggest another way to talk to
the RPi. Which would un-moot the "keep a 'puter at ready" issue. :-)

Remark:

Although I would like to see someone figuring out/realizing what my "but at the same time creating the next" problem is (hint, the cause has been quoted here), I hope that everyone here realizes that this whole "disable HDMI output" subthread is moot, as, as already mentioned, it doesn't do anything for me in regard to my initial question, having the TV switch away from the RPi when the latter is shut down.

Regards,
Rudy Wieser
