Ear Jack The ear jack is loose on the Dell DJ. I have to move my headphones around to hear the music. Is there a way to fix the ear jack?

Nothing works long term, you just have to get a newer, more advanced mp3 player

For a temporary fix, I stretched a rubber band around the base of the headphone jack (where it plugs into the dj) and brought it around to the back of the belt clip thus forcing the metal part of the jack to contact the inside of the female part of the connection. This worked for the past couple years. Since then, however, performance has degraded slightly and now I only get sound from one side...

I had the same problem you had on a Dell DJ 30 I wrapped aluminum foil around my headphone jack and I plugged the headphones in. When I took my headphones out, the aluminum foil got stuck inside the player. I put the headphones back in and tested it and it worked. The aluminum foil is well placed in there and doesn't come out. I just did this a few minutes ago, so I am not sure of the long-term effects of this. Some articles I have read on the internet seem to suggest that this can cause a short-circuit. I am not sure and cautious about this. I will continue to use my mp3 player, but I might discontinue use in my car, for fear of shorting out my car speaker.

Theres a good posibility that the solder connections are the only thinbg wrong with the connections BUT theres a possibility that the Printed curcuit board its self is a flex board and that the flex connections are torn. If thats the case you probably wont be able to fix the unit. If you can open the unit then you can look at the connections and see if its just plain old solder connections?? Good Luck
