    Is my MFD toast?

    I fired up my 95 750 sl today. While looking at the mfd after starting it I heard a "click" come from it and the display went blank. I cracked open the e box and took a look at the fuse and it appeared to be ok. I replaced it anyway. Still nothing. What can I do at this point? Thx

    take a butter knife and insert it on the side of the display between the padding and the display ,to pop the display out of the pad, then unplug then replug the mfd in,,,anything???
    if nothing, just leave the display to the side and grab a multi meter to test for power...

    Are these mfd even repairable? Say at an electronics shop? If possible I rather repair this one then buy another that might fail in a short amount of time.

    Possibly.

    There are instructions posted on here showing how to get the sealed case open.

    Since your display seems to be dead (if you are sure the connector for the MFD has power), there isn't much risk in opening it up.

    There are no user serviceable components inside, but an electronics tech that is willing to spend some time tracing the circuits might be able to get it back to life.

    Thanks for the link. Going by another thread it looks like I might have smoked my mfd given the way I was installing and uninstalling the battery. Looks like its going to be an expensive lesson for me regardless of whether I repair or replace it.
