Horizontal Lines/Dimming on NAV Screen
I took out the unit last week and checked all of the wires, which seemed tightly plugged into the back of the unit. So I am assuming the screen is shot. We have an appt. at the dealership this weekend (my 2010 ML350 is out of warranty, so it will cost $150 for the diagnostic!), but I've seen advertisements by repair places to fix the screen for about $400.
Any suggestions? I assume the dealership will tell me the unit must be replaced or cannot be repaired (or that they do not do those repairs), and try to charge me for a new unit. Would love to fix it myself.
Thanks for any input.
