| [* yellow] ''Look for defects such as: Cracks, Burn Marks, Signs of Corrosion, Swollen Components, Unusual Looking Solder Joints ...'' | |
| [* red] See pictures for example of Solder Joint Defect from this project. | |
| [* yellow] ''Note that the defective solder joints were likely a factory flaw that eventually gave out or were caused by strain, due to too short of wiring as visible by connector angle. '' | |
| [* icon_note] ''See Step 3 for likely cause of strain on connector that resulted in fatigued solder joints. ( Ref: Exhibit - 1 )'' |
