95 F350 351 with EO4D........I was driving down the road and noticed the speedometer wasn't working and the odometer was blank. All the other gauges were working fine. I smacked the instrument cluster lightly one time (I don't know why, just a habit from growing up with old CRT TV's) and both have worked fine since. The truck has never done this before and it was working when I started up the truck. I searched the forum and this seems to be a common complaint.......but if it were the common issues of the VSS or PSOM why would smacking the cluster fix it ( at least for now )? Thanks guys.

FORDF250HDXLT thanks so much! And thanks for posting the links. I am not great with computers so going the extra step to find those and post them is a big help. I will attempt the fix tomorrow.
