I have a Fender Mini Tone Master amp that fell off a shelf about a year ago and stopped working. I recently pulled it out and opened up the back of it, expecting to find a cracked circuit board or a broken solder joint, but everything seems to be fine.

I know this is a long shot given the limited info, but any idea what the problem might be? I'll post pics if it helps. I have a small idea of how electronics work and have some solder skills, but I'm pretty far removed from being any kind of expert in this area. I mostly just play.

Thanks
