    Does anyone still repair mfd's?

    The rectangular handlebar type is what I am referring to. I have a few of them some don't work at all, one works but case is all broken and some are faded. Does anyone still do it and what does it cost? Thanks

    I have lost track of who might still be doing repairs as a service for the oval MFD.

    I have a few MFD here that I am working through for myself. I suppose I could do a few more

    The most common repair is for MFD that are still fully functional but the LCD display has faded digits or sections.

    MFD that do not power up at all are much less likely to be salvageable.

    Internal water damage typically causes corrosion which is difficult to repair properly (result may be unreliable even after repair).

    It is not difficult to transfer the working internals from a damaged case into a good case.

    How many of these things do you have?

    I have a 12 pin with a busted case that works but is a little faded and says lopwr, an 8 pin that doesn't work at all and an 8 pin that's faded. I also have a virage mfi with a bad display that doesn't work. I just tested a bunch of them and got lucky more worked than I thought.

    Are you interested in looking at them? Any idea what you would charge?

    12-pin; case busted on the black/body portion or the front panel?

    See this thread regarding the LoPR warning, calibration and zeroing the hour engine counter.

    8-pin faded digits is the most straightforward repair, I would expect. Don't want to tackle it yourself?

    I might give it a try but I don't have a steady hand for sure so I'm worried about ruining it. The 12 pin is busted in the rear portion of the casing not the screen. I would really like to repair that one.

    Well, if it needs the plastic shell replaced, step one is finding a replacement case.

    I have not yet had a 12-pin MFD apart, so I do not know if it would be straightforward to transfer the 12-pin innards into an 8-pin plastic shell. It might be doable with some re wiring of the internal header connector, or it might just plug straight in and work.

    If you know someone who is a hobbyist that currently works with Dremel cutting tools, s/he might find it interesting to try cutting your MFD open. The main requirement is to not cut too deeply beyond the thickness of the actual plastic.

    I currently use a standard Dremel abrasive cutting disc, but it suppose I should try one of the Dremel plastic-cutting wheels.

    I have opened a 12 pin case, seemed straight forward to replace the insides to an 8 pin, I would be willing to cut your MFDs open and clean the contacts make everything is good to go, if infact you are not willing to do it yourself. i have a few of my own I need to cut open.
