Hi, I have a C220 sport 2007 with the Comand NTG4. last week the screen kept flickering but then was ok till yesterday when it completely went out.
I still have all the functions but no screen. radio and voicetronics is ok. the screen opens and closes ok. i removed the fuse for the comand unit for a couple of mins to reset it but no joy.
I have removed the screen and Comand unit to ensure it isnt a damaged cable etc ( i used to work with electronics before retirement so can fix most electrical items) My question is does anyone have the wiring diagram for the screen so that i can check power getting to it. I have searched the internet but nobody seems to have had this problem. i called a repair agent for help but he said he wanted £289 to fix it. i dont want to pay that amount if its only something simple.
Any help would be appreciated...
