audio system malfunction

Yesterday yesterday, I dropped the screw inside while installing the 3-line display, I removed the front panel with the tape and removed the front panel where the screen was, and after inserting the screen, I inserted the tape a little while inserting it, the audio system started to stop working again, I removed the tape again, I checked it, I checked the connections, but the audio system does not go to electricity. one end is soldered in the socket, and the end is plastic, the cable with thick plastic is always idle, but I thought it might have come out of a soldered end, I said, let's insert the plastic with the solder last time and open it, the sound came from the fuse box. can there be a simple fuse explosion?

man, check the wires in the socket, one of them is probably broken and when you touch it, check all the sockets that change the fuse which has a short circuit and blown the fuse.

I said, I checked the fuses as if there wasn't much trouble in the cable, they said no problem. There is a cable in the blue socket and a plastic in the head of the cable. I don't think the macron is holding tight. Could the cable come out but let me look again.

Friends, my new audio system device has arrived and the room is not working. Do I have to go to the service and activate cd changer again?
