So I have been having this issues with my 2010 Mercedes Benz E350 Sport Screen NOT turning on, I have checked the Fuse (#11 - 7.5 Brown Fuse) it was blown ,so I replaced it with New one, Still nothing. I then went ahead and purchased a new Screen ,and installed it, Still nothing ,I've check to see if there was power in the wire, There is Power. So at this point I am stuck. Any idea as to what could possibly be? Any help is appreciated ,Thank you in Advance.
Your old display blew up its fuse, the replacement still does not work despite good power.
I bet it needs coding to match car VIN. Does your scanner list the "central display" module, can you get into it or just plain missing?
What blew fuse open:
Overheated power supply capacitors went short or missing... The way this module is built with fins you can yell it's a hotty Blower for Comand & display has a FILTER
Did you see a vent duct blowing air through your screen heatsink.... there is a small blower with a tiny filter directly to the right: check its condition: time for service?

what is the picture location? where do I find that?
this blower is located to the right of Comand along left side of the glovebox. You'll need to drop the glovebox out to access this assembly (inbound/outbound ducts, rubber mount insulators)
I think it is hooked up & controlled directly by Comand unit. I remember seeing "Fan: auto" options in the "engineering menus"

Cali, which nook and cranny at the dashboard you have not ventured to ?
Surya you know there are a few modules I've not visited yet, like:
-- SRS main controller located under Comand
-- front bumper 3x radar modules
-- "ESP Premium" (ABS) on driver side
-- Integrated modules (/tranny /steering /ECU).
-- Gearbox selector driver
-- LED Headlights
I can see water has puddled inside my HVAC inlet DUCT, over my blower "resistor"... so I am going to go visit cowl and LIN wiper to grease it and waterproof. I'd hate to waste my electronics with a standard leak. Did you find a missing seal between the firewall and plastic air inlet... right?

I have not venture much at the HVAC/blower , except sending camera to the evap and once cleaning it with chemical from Honda.
I have to inspect it again soon now that we are discussing it. I need to see the filter state of cleanliness which by now is like 10,000KM older.
I know better about the hole near the front sam which I believe it is there for manual clutch if car is manual.
I use that hole to send thermocouple wires from engine bay into the interior.
Hhmm, blowing air to push possible dirt from the evap condensation hoses is a good idea Cali, thanks.
Please take lots of photo when you visit wiper system. I see there is a sealant on the windshield towards the plastic assy/cowl hiding the wipers.
I hate sealant or re-sealing

PWM Blower controller heatsink
Next time you go in to replace your cabin filter (and dust-off tiny Display/Comand filter) drop out the blower "resistor" to check for white aluminum oxidation of the heatsink by rain egress.
