My Odometer LCD is acting very strange. When I start the car after it has been off for a number of hours the display appears normal. Within a few minutes of the ignition switch turned on ( with or without engine start ) the display starts to fade. Within about 5 min it has lost many segments within the LCD display and is also very faded. If I drive around for an hour or so it comes back to normal and stays that way for a number of hours at which point the missing segments appear. If I leave the car off for a number of hours ( such as overnight) I am back to a normal display until the ignition switch is turned on and then the above process repeats itself.
It does not appear to be a loose connection or temperature related.
Has anyone had this issue and if so what was the fix?
Thanks,
Jerry

 

Miata are very sensitive to bad batteries. Have the battery checked both statically and under load.
