Your cmdline.txt doesn't stack up with what I see in the documentation at https://www.raspberrypi.com/documentati ... d-features, namely
"To enable composite output (on all models of Raspberry Pi) you also need to append ,composite to the end of the dtoverlay=vc4-kms-v3d line in /boot/firmware/config.txt:
dtoverlay=vc4-kms-v3d,composite
By default this will output composite NTSC video. To choose a different mode, you need to append
vc4.tv_norm=video_mode
to the single line in /boot/firmware/cmdline.txt, where video_mode is one of NTSC, NTSC-J, NTSC-443, PAL, PAL-M, PAL-N, PAL60 or SECAM"
