Now, we start tearing down the PlayStation 3 (PS3). The shiny upper cover should be removed first. To do this, we needed to remove a hidden screw on a side of the body. Taking off the sticker hiding the screw and sticking a special driver, which is a kind that has a hole in the center of a TORX screw, we succeeded in feeling for and unscrewing the hidden screw.
The shiny cover looked black at first, but we found it actually formed with half-transparent plastic as we took it off the chassis. This is a sort of dressing covers. Under this dressing cover was another cover. We could remove this cover by removing seven screws using a Phillips driver. Then the BD driver and power supply unit came upon surface.
Despite the maximum power of 380 W, the power supply unit only took a small area a little larger than a palm. It was connected with the main board via very fat pins, which looked about 5 mm in diameter, respectively. On the back of the unit were stamped "DC OUTPUT +12-32A, +5-3A." This unit was made in China.
Then we removed the memory card slot, which is packed into a module, and a board, which mounts wireless LAN, Bluetooth and other wireless communication LSIs. The WLAN chip was connected with a diversity antenna.
