Why does the LG LPC 54 cassette player not read flash drives and disks
The LG LPC 54 CD player has stopped playing from USB and CD sources. When playing MP3-files from USB and CD-ROM playback counter starts to work with increased speed, but there is no sound. At the same time navigation on the tracks works. Earlier, the same disks and USB flash drive were played normally. Cassettes and radio work fine. Tell me, please, what could have failed.
Sound from the tape and radio is processed in the analog part of the device. To work with USB-or CD-drives using the digital part, which works on the microcontroller (processor). In this case, it is possible that the software that was loaded into the microcontroller during the manufacture of the radio tape recorder failed. It is hardly possible to fix it yourself, therefore the help of a service center is needed here.
