Car stereo stopped working, without reason?

[Supra Man]

For the record, this is an 02' Accord...

The entire stereo system just randomly stopped working the other day, and I can't figure out why.. Naturally the first thing I thought was "I've lost a fuse somewhere", so I check them,. but they're all okay... Radio and Cig lighter are on the same fuse, and the lighter still works, and the face of the stereo still turns on, reads and acts like it's trying to play a CD, changes radio stations and locks into fm stereo for a few.

I had a friend tell me maybe the inputs or the amp are blown, which I seriously doubt, as this is my grandparents car, and I've never seen them turn it up past two bars on the volume meter, which is nowhere NEAR pushing that system enough for something to blow...

I'm thinking it might be something loose, and I wanted to find the amp and check from there anyway, if there even IS an amp in that thing.. I've also considered the possibility that a plug might be loose...


Any other suggestions, or advice on what to do?
How can I fix this damn thing?

check the ground wire, if it came loose that could be the first problem, i would suggest the sensor but if radio locks on for a few seconds then thats not the problem... if its not the ground wire the only other thing i could think of is that the antenna wire came out of the back of the unit.
