Why is the radio of Wuling Zhiguang not working?

[OGabrielle]

If the playback time changes but there is no sound, it should be due to amplifier damage or the output plug falling off. Relevant explanations are as follows: 1. Check the fuse: Check if there is power, with a focus on inspecting the fuse. 2. Check if playback is normal: If there is power (with display), check if the disc player (cassette, USB drive) playback is normal. If the playback time changes but there is no sound, it should be due to amplifier damage or the output plug falling off. 3. Check the disc player: If the disc player works normally but the radio is silent, check the radio antenna. If the radio circuit is damaged, it generally cannot be repaired by oneself.
