This PlayStation has a few manufacturer defects that showed themselves over time. The first is the inability to sync the controller, while in safe mode the controller is working perfectly. Also it has a storage data link issue where it can no copy the update files correctly tot he HDD. with error code su-41283-8 when trying to update, and SU-41XXX-X when trying a full reinstall. The culprit chip is yet to be found as this is a very intensive search and reball on many RAM chips and the double stacked WiFi Bluetooth chip.
Controller only syncs in safe mode, the hard drive can not be flashed. It seems to be a problem with memory . That issue is very time consuming and a dangerous process. as it requires removal and applying of a new memory chip to each one of the DDR5's. This PS4 is canned until further diagnosis.
We noticed manufacturer solder splatter evident on the entire board. This console passed poor QA inspections at the facilities.
