Question 39Electricity & Electronics - 1st Asst/Chief

The correct answer is B) Corroded pin connectors. Corroded pin connectors on a printed circuit board can sometimes resolve themselves once the board is removed from its edge card connector and then reinstalled. This is because the act of removing and reinserting the board can help break through any corrosion buildup on the connector pins, restoring the electrical connection. The other options are incorrect because: A) Leaking components would not be resolved by removing and reinserting the board, C) Open traces or broken connections would likely not fix themselves in this manner, and D) Discolored or darkened components are usually a sign of more permanent damage that would not be resolved by this action.
