+[title] See if your issue might be caused by a poor contact
[* red] The headphone jack is shown with a red ring.
[* icon_caution] Wear a grounding band or at least ground yourself before proceeding.
[* blue] Apply gentle pressure to the 2 areas marked in blue with your finger.
[* icon_note] This pressure slightly flexes the area and may cause poorly soldered pins to re contact.
[* black] If the sound returns and the red light turns off the issue is likely caused by a poor solder connection on the board. If not this fix may not work for you.
