    I brought my Prius 2010 to car wash and after wash I found out the fuel gauge, speedometer and MPG are not displaying any more. Hybrid piece on the right shows OK.

    One side of the display is actually projected from below. May or may not be the case, but verify there's nothing sitting in there, covering the projector, say a business card, something like that.

    Appreciate the tip but I checked and found nothing. The energy monitor and clock display well but nothing on the left side. I am driving without knowing what speed I am driving at. - Could it be the fuse ?

    more likely a bad multi function display, although the 12v can sometimes cause this condition. check the voltage at the jump point in the morning before starting the car

    I have finally fixed it.
    I removed the dashboard. Removed the speedometer Cluster then removed the flex of the projector. Cleaned the flex and reinstalled every thing back. The projector started working well

    By 'flex', you mean something like an FPC connection to the projector circuit board?

    or something else?
