    PS5 EDM-031 - Pulsing BLOD - SSD NAND chips never heat up

    PS5 died in the middle of a game and never would boot again. Pulsing BLOD stays on forever but never boots.

    No LM damage. UART gives a generic "APU not responding" error.

    Under thermal camera, the SSD NAND chips stay stone cold. The controller warms, but not the NAND. I have a good 2.5v and 1.8v around the NANDs...

    I don't have a ton of PS5 experience, but I assume that the NAND would need to warm at least a little bit in order to boot...

    So to those with experience, would you expect at least a little heat from the NAND during the boot sequence? And if yes, is a bad controller the likely cause considering NAND voltage is present?
