dead MP3 player, I need Help

[rascard2007]

HI to everybody I´m "New inTown" in the mp3 players subject, the mp3 player of my girlfriend dies, when you turn it on says "Hello" and stays there. After removing the battery and connecting to the USB in the PC it´s recognized as "external disk" but have to be formatted. once formatted can be used as a flash memory, U can copy and read information. but if U try to use it again as mp3 player U get the "Hello" again and U have to format it again when U reinsert it in the USB port

I´d the device disassembled and got the following information from de chips:

Board: MU540HS_Rev 4.0_061225

Memory: Hynix KOR
HY27UU088G5M
TPCB 708A

Chip: A1568L
A126-07-P
0627CXF
B51054

the chip seems to be from AVID

So I need to correctly identify it and what can I do to fix the problem? See Pic below

Thanks
