What you'll notice
The picture drops out unless the cable is held at a specific angle, or the port visibly wobbles.
Why it happens
A port that has come loose from the mainboard through repeated cable insertion, cracking its solder joints.
How we fix it
We re-solder the port securely to the board — a quick, affordable and permanent fix for this specific symptom.
