Details

The southbridge on a PS4 handles many supporting functions, so when it fails, the symptoms can look unrelated. On CUH-12XX consoles, the CXD90036G is that chip, and the listing says it manages USB, the hard drive, audio, networking and power-related functions.

This listing sells the CXD90036G southbridge IC for PS4 CUH-12XX consoles. According to the listing, it resolves startup failure, faulty USB ports, hard drive detection errors and network faults.

Indications for replacement

The console won't start or loops at boot.
USB ports stop working.
The hard drive isn't detected.
Network faults after a surge or liquid damage.

Recommended approach

Rule out the hard drive, the power supply and the USB ports first, and inspect the board for corrosion or damaged parts around the chip. Southbridge replacement is BGA work, so use a preheater, reball carefully and clean the pads well. Protect nearby parts with heat-resistant tape, as the CUH-12XX board has small components close to the chip.

After fitting, test boot, USB, hard drive detection, network and audio to confirm everything the chip controls is working.
