[RPi3b+] Composite Video Issues

Hi Folks,

I'm a first-time user of LibreELEC and I'm trying to get composite video working with my RPi3b+. I did a fresh installation of the latest version of LibreELEC and I thought I followed the instructions in config.txt correctly, but for some reason I still can't get a composite video signal or the output to work. For reference, I've been testing the composite output on an old CRT TV as I'm trying to create a retro setup for 4:3 SD video content.

I made the following changes in config.txt:

Quote

[all]
################################################################################
# Use distroconfig-composite.txt instead of distroconfig.txt to enable
# composite video output.
# The composite video mode needs to be configured in cmdline.txt:
# For PAL add: video=Composite-1:720x576@50ie
# For NTSC add: video=Composite-1:720x480@60ie
################################################################################
#include distroconfig.txt
include distroconfig-composite.txt

I also made the following change in cmdline.txt:

boot=UUID=1808-2032 disk=UUID=0a133ec0-0084-4da2-9ade-096d75fe9be8 quiet video=Composite-1:720x480@60ie console=tty0

I haven't made changes to any other files. I'm attaching copies of both of my .txt files for reference. Any help would be greatly appreciated, as I've been trying different variations in the .txt for a few days now and still can't get it to work.

Thank you!
