Switching on impossible

[newcastlepetz]

hello,
i've got a little problem with my zen micro. from one day to another the player freezes at the creative symbol everytime i try to switch it on. i did a formate, clean ups, loaded the battery full - i even smashed it (carefully) against a hard surface (O.o), as i got the advice in another forum. but the player's still the same...
i got advised to replace any card or something, but to be honest - i am not that good in technical stuff and i really don't want to break the player totally up when there's still hope to repair it (actually is there any chance to get it fixed again?). e.g. can i send it to the manufacturer or someone to get it repaired? or is it cheaper/more advisable to do it on my own, even though i'm not that into technics ect?
