Help diagnosing the issue with C4 GP 2015

[xCiNx]

Hello

i recently got C4 GP 2015 with newly installed main display. all was fine until few weeks ago when the display kept switching off .. now im in stare where the panel does not come on even when opening the doors or starting.

so i got this errors :

U0028
U0028(96)
U131D

when the display goes off i cant even use the tempomat , when i stop and activate the handbrake . the light on the button also does not come on .. before i go to citroen i want to ask if there is any solution or if anyone had this issue too.

thank you very much for any help

My initial thoughts would be did you replace the display with the exact correct part number. There are variations to these and the incorrect one will have issues or unexpected behaviour. Secondly, when you replaced it did you configure the new part? I suspect there may be options that need to be coded if being replaced.

was done by previous owner and in citroen service center. sadly i cant be without car since my wife is pregnant and will deliver soon so im kinda in bad spot.
seems like i will have to bring it to citroen sooner than later

thank you for your help
