[SOLVED]Cannot enable TV out on Oranghe Pi PC

Portokal

I am trying to enable the TV out or an OPI Pc for a few weeks.
So far- all in vain.
I have installed the latest Armbian (say the latest for the last week).
There is some flickering on the TV and that is all. For some reason there is no image on the display, connected to the HDMI output, so I have to reinstall Armbian after each attempt.
I have connected the cable as displayed in the image attached. I believe it is correctly connected as the audio output uses pin 3 as Common and it plays just fine (including balance working fine).
I have added TV in the /etc/modules file but does not seem to make any difference  any way, since after commenting it, there is still no image in the HDMI display.
Am I doing something wrong? Any help will be highly appreciated.
Forum does not allow me to uppload the fex file.

Thanks for the help!
I swapped both pins of the RCA connector and now thing are fine (except the quality of the image, which flickers too much).

1. Also regarding:

1. 1 – Make a script.bin backup:
sudo cp /boot/script.bin /boot/script.bak

This did not wortk for me. Imho the correct action is : sudo cp /boot/bin/orangepi.bin /boot/orangepi.bin.bak (orangepi.bin or whatever script.bin points too).2. I did nothing to enable analog audio, it just works. I just resoldered pin 3 to pin 3.

3.

9 - Include the TV module driver to system startup drivers:
sudo echo "tv" >> /etc/module

This action seems useless. I have commented tv (added a # before it), and still TV out works.

Thanks for the assistance once again!

I increased the distance between the power supply and the OPI. This way the noises on the image are gone, but it is still blurred.

I am trying to get tv out working on an older orange pi zero.  I have installed the latest armbian image.  Here is the "lsb_release -a" return:
Distributor ID:  Ubuntu
Description:     Ubuntu 20.04.2 LTS
Release:          20.04
Codename:      focal

I am currently operating headless and the login splash screen says "Welcome to Arbian 21.02.3 Focal with Linux 5.10.21-sunxi"

I am trying to use the 13 pin connector.  Pin 2 = ground (shield) and Pin 9 = video signal (center conductor)
I have found forum threads about enabling the tv out including this one.
My current installation does not have a /boot/script.bin file ...
Other forum threads also refer to files that I do not have.

This thread says:
("the OPZ will not use the tvout port, unless you add "tv" on the /etc/modules file")
I tried adding the letters "tv" on the second line of my /etc/modules file but still no output.

Can anyone offer some suggestions?  
Thanks in advance!
