Re: Display has just black screen
Usually the red cable is VIN. But as always, be safe and use a multimeter.
With VIN i do not mean Video Input but where you feed it with power (+).

Re: Display has just black screen
This is not 100%. I just tell you what i have experienced on other boards.
Most of the time it works if you desolder the right IC and solder a wire from 5v to the right leg directly.
Take a look what leg outputs 5v. If you are careful, you can even resolder the IC, if it fails.
If not, you might damage your board. Be aware of that.

Re: Display has just black screen
I used a Pololu 12V Step-up Voltage regulator (U3V12F12) to feed my screen 12v, easier than desoldering a tiny IC, and also made the image less 'stroby'

It is pretty small. I have it in use, too.

Re: Display has just black screen
The first one is pretty big compared to the pololu.
The second one, i am pretty sure, is not suitable for this kind of task.
And the third one is a step-down module.
