Reasons Why A Power Jack Will Not Go Up or Down
Question:
Power Jack will not go up or down after lowering them

Expert Reply:
There a few common reasons why a power jack will stop going up and down. The most common is a weak ground connection. If the jack grounds through the mounting hardware then you want to make sure that area is free of corrosion because it will not be able to get a good ground with corroded hardware.
Another reason is the battery is not charged enough to power the jack or the jack is not getting sufficient power. If you let me know exactly which jack you are referring to, I can give you more specific information.
Lastly, the jack may have been overextended and damaged the internal workings like the gears. If that is the case, then you would need to replace the jack.
