Circuit Sword Lite - first boot - TESTER and NORMAL mode showing only RGB

Hi all,
I managed to solder and connect the raspberry pi zero w on the board.
I am now on step 20 after changing the mode to TESTER. T
The problem that I have now is that after turning the switch ON, the display is showing only a flashing screen with Red Green Blue and White in a rolling fashion. At some point a turned it ofd because it was clear that there is an issue there.
The screen connector seems to be connected fine and the raspberry pi is turning the green status led on when it powers up.
Any suggestions?
Kind regards

Do the reverse in step 19:
Open the `config-cs.txt` file using "Notepad++" then change `MODE=TESTER` to `#MODE=TESTER`

Hi,
do you mean to use the NORMAL mode instead. Because I've done that and I have got the same problem with the screen.
Any advice?
Thanks

I think it might be something related to the LCD screen.
I enabled SSH into the retropie, ssh-ed into the raspberrypi and manually run the Test script that looks good.

Could it be something related to the soldering of the raspberrypi?
This is the current situation. No TESTER mode.

I managed to make it working.
There was probably a bad soldering in one or more of the pin of the raspberry pi.
I've looked at another post here in the form and someone had a similar problem. Then I checked all my pins and 3 of them weren't soldered perfectly. I fixed them and there it was, it worked.

.
Thanks all the people have contributed to this forum. It really helps. I'll move further on my build now, my first build and I'd like to add a post with my build when complete soon.
Thanks.
