Pioneer MVH 16 Sound Issue

Hello, I have a Pioneer MVH 16 car radio that worked well for 1 year and 4 months, but now for the past 2 weeks, the radio turns on but there is no sound. I noticed that the auxiliary cable jack was starting to malfunction until the sound completely stopped working, whether on USB, radio, or auxiliary. So, I disassembled it and found some cables that are not connected. I'm counting on your help; here are the photos:
- a light blue and white cable that is disconnected
- a yellow and black cable
