I have a 2006 F150 4x4. A few months ago my digital odometer started flashing on and off sporadically. Then, finally, it shut off all together. The screen is still lit up, but no digital readout will show. Where should I starting looking?

 

The same thing recently happened to my XLT. I haven't had a chance to do anything yet but I have read a few places that you need to open the dash and replace the bulb.
