This process may reveal a bad display, and also gets the cables reseated.
If you are still having the problem, swap cables between displays, then swap them end-to-end making sure the red stripe is to PIN 1 on both ends.
J22 is Display Data. With the battery corrosion you almost certainly have poor continuity to J22 and probably the J22 header pins themselves.
Quoted from wildinindiana:Okay, I don't have an off board solution at the moment. It is a brand new battery holder with new batteries... Once I get my order in with the off board solution, I will swap them out. Not sure why I'm inviting it to happen again with the corrosion remediation, and a new battery holder...?
Not trying to brow beat you into submission. People forget about batteries sometimes. Even new batteries can leak. It is better to have them off the board asap. An original style battery holder can be remotely mounted with little effort.
The risk is just too great to leave batteries board-mounted. Simple quick task verses what you are experiencing now with corrosion.
