Power touch screen stereo 7023b was installing my car it worked for a while and then just stopped working the floor and water also stuff working I checked all fuses diffuses are fine sometimes a video goes to start but then it shuts itself right off what can I do fuse is fine and I just put in a new battery I haven't disconnected it so I don't know if it's has to do with the power coming in because it was working fine before helped me please

We have a cd stuck in the player. Is there more than one fuse box? The wire from fuse box to battery sometimes has to be jiggle in order to start. When we do get it started the cd player will run a good 2 to 3 min. Sometimes the car shuts off in the middle of the road. I have no money for repairs so I am trying to fix it myself
