    Hi Everybody

    Since a couple weeks my VDS display is kind of dark and it is almost impossible to see the information on the display.

    If I go into the contrast settings I can do the following steps.



    but after a couple seconds the display is dark again.

    Anybody can help or does anybody have an idea what I can do? I belive the screen should still be ok as he lights up for a few seconds everytime.

    BTW I rebooted the VDS allready and it does not change anything!


    Thanks a lot for any suggestions

    While I've never seen anything like it, your VDS display could be dying out. I've heard they're about $600 to replace, though I'm not certain.

    If you can access the Diagnostic Menu, you could try Inhibiting APS and then turning it back on.

    Like DeedWest mentioned I would try a reboot if possible. Luckily OVMS can control everything the VDS does so if you're screen has gone kaput you have another method of controlling the car.

    I hope Tesla has a spare one in their ever shrinking parts bin, but in the meantime OVMS seems the way to go.

    Interesting thought to use OVMS, but it can't do everything. Much, actually, at least as it is now. And it totally depends on a working CAN bus, so if your VDS isn't talking to the VMS (ref Communication Problem Service Required (id:1900)), you're stuck.

    (Related question: when you disable APS, can you still open the driver's door from the key slot at the bottom?)

    Thanks everybody for your answers. So far Inhibiting APS didn't change anything at all. You need to know that the display works fine I can still use all the functions in my dark garage. Just the contrast is very low and the light also. But I still can use it. the problem is that I outside with sunlight I can't see anything at all.

    So you guys think to replace the display will solve the problem?

    The weird thing is it looks like it works fine for a moment and then suddenly it goes back to being messed up.

    Certainly wouldn't hurt to have Tesla take a look. Things like this worry me as our cars get older.

    Is it a backlit led display? Sounds like the backlight is going bad.

    If the back light is bad it would not be able to hold brightness as shown in the video. Seems like it won't memorize the contrast change adjustment for some reason.
