Hello -
My 2005 SL500 screen recently started showing odd small, random botches of a few pixels in various places on the screen. I purchased a replacement screen and have removed the COMAND unit from the SL before.
Does anyone have any documentation on doing the COMAND surgery to replace the screen?
Thanks in advance -
David
Bump... anyone else have any insight? My screen appears to be washed out or otherwise damaged (from the sun? It was a Florida car) and needs to be replaced. I’d like to DIY it.
I would also be interested in this. Isn’t there a shop in Florida that repairs this? The screens seem to be more expensive than the entire Comand unit. Why is that? Can AliExpress be trusted?
If anyone is interested I have a complete Comand head unit available for sale. Works great, the optical drive works fine, and the screen is very good condition, not burn-in or discoloration. I pulled it out of my 07 SL550 when I did a head unit upgrade to a Kenwood..
PM me if interested.
PS. I want to sell the whole unit, not just the LCD panel, so please don't ask me to part it.

Not going to ask you to part it, but if it’s not too much trouble do you mind telling us the part number for the LCD screen?
First try and source the screen. Once you have the correct part, look for someone local to fix it . They're a ton of retired guys out there they used to fix TVs and stereos and now fix Bose stuff in their spare time. Somebody that's competent in fixing auto gear should have no problem fixing this deck. It's nothing special.
I finally got around to pulling my COMAND unit and taking it apart. Not a terribly difficult or complicated job to get the display out. Here are pictures, looking into figuring out the right part.
Does the display have a uv filter ? Mine has a huge sunspot but one day with the top down and the sun directly behind me it went away..I could see the entire display, I was stoked. Then I moved the car and it came back. I know the guages have a polarization filter that can go bad. Any input ?
I had some MAJOR scratches on my 2003 SL Command System screen after a "well meaning" detail shop '"cleaned" my screen!
The screen was so scratched that it was really not visibly use able. After trying to lightly clean/polish the screen .. I researched ALL the various options and upgrades from used command systems from other 03/04 R 230s .. since the 05 and newer are NOT interchangeable !
I read all the threads on this site and considered the large Chinese larger screen GPS reported replacements ..
Finally I realized the Command Screen internal display is projected onto a polarized surface film from a glass screen
I carefully scraped ALL the old FILM from the glass command screen and then ordered POLARIZED PFHC - AG/HC linear polarized film sheets from "A Flash"
Ste.108- 404, Shavano Park, Texas 78232 www.polarization.com for about $40 . The polarity works at a 45 degree angle to the projected image .. So measure the screen , take the peeled TOP polarized sheet and orient it to the desired angle and CAREFULLY cut it slightly larger than the viewed screen - (to slide under the edges).. BEFORE PEELING THE BOTTOM ADHESIVE. Then carefully work the new film onto your CLEAN OPAQUE screen .. and VOILA'
You can save a LOT of strife and keep your original system.
BTW this same fix should work on all later Command Screens since the have the same projection concept ..
So, new screen is in but it looks like the display is somewhat misaligned/cut off? Does anyone have any ideas?
To follow up on this, I returned the screen and bought another one with a part no that matched exactly my original screen and everything lines up perfectly. Not sure if a quality control issue or what. Someone asked for some instructions and here’s what I can offer:
As far as tools I’m struggling to remember anything beyond a few different torx bits. you can find videos on YouTube of the COMAND unit being removed. It’s a little time consuming but not terribly difficult. IIRC 2005-2008 does not require the clock/ac vents to be removed.
Once the COMAND is out, the screen is actually the easiest part and fairly self explanatory. There are 4(?) screws that attach the faceplate/controls to the rest of the unit, and then a bunch of smaller screws to take off a couple of circuit boards.
got this additional info by PM — can’t verify
there are adjusting screws on the back of LCD screen V & H they adjust height and width of the image on screen

hello, realize the post is old bt figured it was worth a try. available?
I can do replacements for 07-08 model command screens turn around time currently 2-3 days cost may depend on whether liquids have been spilled on the unit from the adjacent cup holders.
PM if interested.
