I don't know exactly which model of the Thomson Lyra you have, but you can visit the Support page on their website, find your particular player model, and download software updates that might help solve this problem.
Hello Jan, tell us what model is your portable CD player Thomson
I wait your answer
Greetings Franco Dosil
Hola Jan, comenta que modelo es tu portable CD player Thomson
Espero tu respuesta
Saludos Franco Dosil
Murdo's tip to trim off the cover of the AA battery base to expose a few mm of metal is spot on. Replacement rechargeable batteries for my Thomson wireless headphones did not charge, no green light, utterly frustrating, till I read Murdho's suggestion. Thanks for that

It might be a french product . Not sure if you need to speak french but you could ask them if there is a user manual ?
Maybe use a translator web site and put french in as well in your request .
When you connect it to the computer is it showing as a portable drive? IF so you should be able to browse it and delete them that way, or you could format it .
