Hardware Which Areas Should be Checked if SD card reader not reading?

[justaplaneguy0]

Looking for some help on identifying areas on the motherboard to check if the SD Card reader isn't reading after testing with 2 known to work SD card readers. Are there any particular areas of the board that should be checked for shorts? Any common faults here?

SD is going to report directly to GPU looking at the board layout. Likely takes 3.3v in from the PMIC on those capacitors above the connector. This would seem to indicate a problem with the connector, possibly a missing/failed component above? I've seen tons of knocked off resistors on game card connectors, could happen here.

For the SD card adapter on the motherboard you can check this thread for reference which point to solder if you if the SD module to the SD card flex isn't working.
