In this case problem with bootloader/flash memory. Because Sony not share their firmware and not permit to open bootloader, sure only service center repair your problem. Common fix is motherboard replacement.

Hope it help. If not try instructions above. Also try eject micro sd before power on. Also if you have access to usb power meter - ckeck if you dap actually charging.

If your dap wasn't in use long time sure it deeply discharged. Try to plug it to PC or Mac and wait a hour or so.

Can someone share service manual again? Getting close for battery replacement. Which part number battery right ? LIS1623HNPC (1275mah) or LIS1650HNPC (1500mah)?

HI! Got 004 mini today. Optical input not work. Can someone take photo of the board near optical connector and connector itself? Sure it broken.
