ColorMFA

I installed using the tutorial from the site. All steps are completed.
On the PCB of ColorMFA I receive 12v from cluster. No image on screen and no power on the led of the PCB of ColorMFA.
The diode is ok. What I should check ?
Thank you!
Cluster is VDO immo3 from Passat.

Check your ground if it's in correct place. Maybe you soldered it in the wrong place. If this fails the test, try to unsolder power wires and hook them to an external 12V source and see if the screen powers on. If it's not, it may be a PCB problem.

Ok. I will check you you mention here. Thank you!

Please check if all cable connections are soldered properly to pcb's (no shorted) - attach photos here if You can.

Correct!
One bad solder at 12v.
Checked twice and that was wrong.
Thank you guys!
Tip: use more flux

Sorry for the long silence, was away and without normal internet.
It’s good that everything worked out.
And thanks lateralus and mmgherasim for the help.
