Step 3: Fixing a bad video connection
Use the following steps to make sure the video connection between the PC and monitor is good:
1. Remove the video cable from the computer and monitor.
2. Check for bent or broken connector pins or broken pins that have become lodged inside the
holes of the video connector on the computer. With the monitor and computer off, straighten
bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a
retracted pen. If any of the pins have broken off from the cable and are stuck in the small holes
of the video connector (on the computer), remove the broken pins using a metal sewing pin (or
similar metal pin that is thin and has a point).
