Hello! I have built the K8095, and it does play mp3s. Unfortunately, the buttons are not working. Most of the time, the play/pause button works, and when it does it only plays. It does not pause. I have to unplug the player to stop playback (this happens 95% of the time). None of the other buttons work. What should I troubleshoot first? Note, I am not an electronics expert. I am in class for electronics, so I am still learning.
Thanks!
