tape failure

I'm new among friends. I had a question when my car stereo started the tool. closed, won't open yet. I took it to the electrician, he said the fuse is solid and the tape is gone. I bought a tape, put it on and tried it, then the room went and won't open when I pressed the starter. why do you think this problem is?

Hello, there may be a problem with the tape cables or the fuse. something is shorting out

The tape started to work, it goes away, I couldn't understand. I checked the cables, no problem.
