Need suggestions or help with resolving PS5 issue of blue light, beeps once and does nothing else. I purchased the motherboard and matching optical drive daughterboard PCB from eBay (including snapshot of item description from seller) for parts not working. Seller was very communicative. I was able to obtain UART connection from Console Service Tool and UART-CL which both show same and only error 80871001 DDR4 Error - Power Failure or Short Circuit. I found a SSD PMIC voltage diagram by DylanBBK and the all my voltages match. I contacted a Facebook console mod business and they have not had one with this issue come through their shop before and informed me that next to the SSD controller should be a single DDR4 RAM chip that holds the SSD cache and should check the voltage which I am unsure of what the proper voltage(s) should be. I searched the forums for error code “80871001” which yielded no results. Has anyone else had experience with this issue? Any help or thoughts would be much appreciated. Hopefully I did OK for my first post. *I have a private video Youtube link that the Ebay seller provided showing their diagnostics on the board, but apparently I cannot add links and/or attach photos.
