The Raspberry Pi Model B+ and up, including the Raspberry Pi 3 , all have the RCA jack unified with the 3.5 mm audio jack, you'll need a hybrid cable which has all three of the RCA output jacks, (yellow, white and red).
After connecting it to a TV (CRT), you'll notice that it isn't enough, so you'll need to tweak it by editing the config.txt. There are three things you need to modify.
Search for that line in /boot/config.txt. Remove the hash symbol (uncomment it) and change the 0 after the = symbol to what your CRT TV's mode is from this list.
sdtv_mode=0 Normal NTSC
sdtv_mode=1 Japanese version of NTSC – no pedestal
sdtv_mode=2 Normal PAL
sdtv_mode=3 Brazilian version of PAL – 525/60 rather than 625/50, different subcarrier
Add the line in the brackets here (hdmi_ignore_hotplug=1) to the bottom of /boot/config.txt
Search for that line in /boot/config.txt . What you've got to do is to add a hash symbol in front of it, or comment it like this: #hdmi_force_hotplug=1.
And you are done!
Hope this helps you!
