rpi4 - no signal on old TV

  • Hi, I'm trying to make the rpi4 with libreelec to work on an old SABA tv but the tv says "no signal".

    I have tried to change the config.txt with different options related to the hdmi, but probably I didn't find the proper combination.
    The rpi4 works properly on a newer LG monitor, so the sdcard is ok and other the rpi4 should be configured properly, but when I put the HDMI cable on the SABA tv it does not work (no signal).

    This is what I found on dmesg when I connected the cable on the TV:

    Logs before should be irrelevant because they were the same even if I didn't connect the SABA tv.

    I tried once to startup the rpi connected to the working LG monitor, checked it was ok, then disconnected the cable from the LG and reconnected it on the SABA tv, and strangely it worked.
    This is not a proper workaround because I don't want to switch the hdmi cable every time, but at least it was a signal about a working SABA tv.

    Can you please help me to resolve my issue? many thanks :)

  • An easy workaround is to boot your RPi with the LG monitor connected, then ssh in and run "getedid create".

    Then your RPi4 will "think" it's always connected to the LG monitor and ignore the broken EDID of your SABA TV.

    so long,
