Sync 3 screen is very dim


I have recently installed a new sync 3 APIM and screen to upgrafe from the sunc 2 that was installed from the factory.
After installing the parts the system works i have programmed it with forscan to match my vehicle everything that i want working works.
The only problem i have is that the screen is very dim, i can change the brightness in the options but that does very little.
I can see that the screen brightens and darkens a little when is use this option.
i have tried changing the illumination strategy in forscan to B but it did not help.
the part are oem ford sourced from ebay.
Is there anybody that had the same issue and can help me?

Kind regards,

I have been scouring this forum and the internet the past few days but to no luck.

Seems i never got back to this post, @ludzervaatstra did you get your issues solved?

Yes it turns out the screen itself was bad replaced it for another one and it was fixed.
