L702X Defective headphone jack

I'm wondering if anyone else has experienced this problem.  My L702X has three jacks on the side.  One is for headphones.  The other will work for headphones or will receive a digital audio adapter.  The last is for a microphone.  The headphone jack is the frontmost.  I recently noticed that it no longer retained the plug that had been inserted.  It still made electrical contact but I had to hold it in with my finger.  I reported this to Dell and a technician was sent out.  He changed the daughter board containing the jack.  Upon examining the defective jack, we noticed that when the plug was inserted in the jack, it pushed a small piece of plastic out the back of the jack.  If I pushed this back in with my finger, the jack would retain the plug again.  Interestingly, when he installed the new daughter card, the same thing happened.  He placed a call to Dell who wanted me to send my machine to the Depot which I thought was extreme given the problem was with a removable board.

Today another tech came to replace my keyboard and while the machine was open I took some photographs of the bad jack.

In the top picture the plug is seen at the bottom of the screen being inserted into the jack.  The bottom photo shows the result in which the black plastic piece is being pushed out the back of the jack.  This is the "new" board.  The old one had the same problem.

Anyone have a solution for this?
