[RPi4] My TV remote controller stopped working on KODI!!!

ivansuperpower · January 28, 2025 at 9:33 AM

Hi there,

I've been using Kodi (21.2 (Omega)) + LibreELEC (12.0.2) on a Phillips TV without issues moving through all the options & KODI menus with my TV remote controller. But suddenly this morning stopped working. Apparently my TV last update was months ago so I don't know what's going on. From time to time I update manually (when I have notifications) KODI add-ons but nothing else. This could be the problem? A bad add-on update?

I've activated the debug log on the CEC module and I can see a lot of these messages:

Asking IA told me that this means "Issues with CEC (Consumer Electronics Control) communication, indicating repeated failures to send POLL commands to the TV" but I don't know how to fix it.

Any idea? I really appreciate any help you can provide.

Exceuting the "cec-client -l" I can see the there is a device found but no idea if this is correct or not:

First make sure you are connected to primary hdmi port (hdmi0 - the one closest to power connection).

Next, disconnect TV from mains for several minutes.

Remove all HDMI connections, and just connect one HDMI from TV to Pi (no AVR etc).

Power on TV first, set to Pi's AV input, then power on Pi 4.

Does CEC remote work? If so you can try connecting the other hdmi devices..

I've change the microHDMI port and now works perfect again. Thanks for the info! I forgot that RP4 has two microHDMI ports. But why is better to use the primary one? I really don't know what port was using before because I have the RPi4 whitin an Argon40 case and I don't know what port internally is connected to the closest to power connection...) Now I'm using this one

Anyway, my issue has been solved so many thanks for you help!!!!

The HDMI0 port is the preferred one to also support 4K@60Hz (AFAIK: HDMI1 of the RPi4 supports max 4K@30Hz). With LE 12.0.1 there was an attempt to support CEC on both HDMI ports at the same time, but this caused more problems than it helped. This temporary function was dropped with LE 12.0.2.

I didn't know! Thanks for the info!

I have had the same issue. When I roll back to LibreELEC-RPi5.aarch64-12.0.1.img, my TV remote works. However when updating to 12.0.2, no matter what HDMI port I use, the TV remote does not work.

I have followed the instruction set above but no luck for me.

Cheers MRF.

I think I have same issue. But I use orange pc plus, and yesterday I connected my father's Philips TV and we could see video but didn't have sound and TV remote didn't work but my brother's changed HDMI to 2nd port and it worked. We could hear sound and use TV remote. But it did not work for long. If I turn off power Orange and TV after when turn on they don't see anymore. TV doesn't see Orange as Kodi(doesn't matter if I turn on TV first), but if I change HDMI to 1 port it works again(this means that if TV is connected via HDMI1 I have to switch to HDMI2, or vice versa(HDMI2 -> HDMI1)), TV show HDMI use Kodi and we can hear sound and control by TV remote.

Can anyone test this case that has the same issue? Because I don't have Orange now and I can't test to change version.
