Today I worked on an idea I had. I have an iRiver E100 MP3 player. I stopped using it because the headphone jack stopped working. I had an old phone with a jack so I thought I might be able to replace the jack in the E100 with one from the phone. That did not work because as I had figured the jacks were not compatible. But what I did figure out was that the jack was corroded. I cleaned the jack and that made it so one of the channels would play. On closer inspection I found that the jack itself had pulled away from the board. I then decided that I would try to fix it with a little wire and some hot glue.
Here is the results of soldering a small wire to from the jack connector to a small exposed run on the board. I had to scrape the coating from the run. There are two green arrows pointing to the soldering.
There was not much room to solder but after struggling for a while and then having to re-solder one of the connections. It worked.
Here is a video of the process, I sped up a lot of it reduce the time of the video.
I also took a long walk since the weather was cooperating.
