Introdução
If your SD card is not being recognized properly, or if the slot is physically damaged, the fault likely lies with the SD card reader component itself.
This repair is an intermediate to advanced procedure that requires disassembling the PRS-505 and replacing the SD card slot, which is often soldered directly to the main logic board.
Warning: This guide requires handling delicate internal components and may necessitate soldering skills. The aged plastic casing is brittle, and you must take anti-static precautions to avoid accidentally damaging other components on the circuit board.
