Why won't it power off?

I learned some basic microsoldering in your videos and replaced the battery in my 2x2" watch style mp3 player (not a brand name). Now it will not power off. Wondering if I damaged something in my soldering process. Would appreciate any feedback!

@vienna79444 post a couple of pictures of your solder connections and vicinity. I am thinking solder bridges etc. are a possibility
