RPI4 - HDMI-CEC not working

Good afternoon,

TV Model: Samsung UE55es8000

Raspberry pi model 4b

libreelec - tried all versions available

Please note that HDMI-CEC doesnt work on PI4 with my tv. its been working fine with pi2 and pi3b's but not with pi4. Everything else works flawlessly but not hdmi-cec as a result, cannot use the tv remote with pi.4

I've tried changing cables, ports, reset, different versions of libreelec - nothing works.

I'd appreciate if someone could help me.

Cheers

MJ

Are only Samsung TV's affected by this issue ?

So far, yes only samsung users have reported cec issue

I doubt very much this will help but watch this:

Thanks but this is very basic requirment for hdmi-cec to work, if this wasnt on it wouldnt have worked for rpi3 or anything else but it does. just rpi4 isnt working

CEC works on my earlier Pi's, and I've never had CEC connection issues with my samsung, beside buggy stuff that can be fixed or worked out.

My micro hdmi cable is old though, so I will look into buying a new one in the coming weeks.

I've done all these test and can confirm hdmi-cec doesnt work (atleast) for samsung tv but worked for earlier rpi's.

Bump*

ok - cec-not working so far on panasonic or samsung tvs on RPI4 which previously worked on all pi's.

If any developer watching this thread, please help?

Hello all,

LG tv same problem.

RPI 2 & 3 - CEC works for years, RPI4 not working.

Thanks for fix.

Edit:

Sorry, I was to fast with posting.

After googling in some other forums, I have found, that for CEC to work, HDMI must be plugged to the port next to the usb-c/charging port. Moving the HDMI cable from the other HDMI port to this one helped and now the CEC is working as well.

Might be a good tip for someone new as me

Glad it worked for you by changing port but unfortunately it does work for me no matter which port its plugged into.
