[V8] Trip Computer Display

[brad at speakoutpro.com]

I just had two Power Steering hoses replaced.  Coincientally, 
one (just one) of the six LCD display options on the trip 
computer no longer appears -- just blank.  I think it's the 
top middle position of the display.  All other five readout 
options on the trip computer work fine.  (As you cycle 
through the options by pressing the button on the right 
stalk, the five options display fine, but the one in question 
is blank).

Is there something the repair tech may have done that would 
result in this?

Thanks,
