SCPH 100x SERIES

Stealth Chip Installation Instructions

Before disassembling the PSX unit be sure to have a clean, well-lit work area with storage containers for loose parts. You will require a 15 watt pencil tip soldering iron, a phillips head screwdriver, solder and electrical tape to secure the MOD chip to the PlayStation mainboard.

Disconnect PlayStation unit from power source as well as video hookups. Remove any memory cards or compact discs that may remain in the system. Flip the unit over and remove the (5) case screws. Store screws. Turn unit right side up, and remove the top half of the case.

The CD assembly is to be removed next. Begin by locating the ribbon cable connecting the lens assembly to the mainboard. Firmly grip the ribbon cable at the large white base connector and begin to gently pull upward to free the ribbon cable from the base connector (on some of the early model playstations such as the  SCPH 100x and SCPH 3000 series you may have to lift the black socket a little bit in order to release the ribbon cable). Close attention must be made when handling this cable. It is extremely fragile and requires extreme care. Once the ribbon is free, pull the remaining connecting cables from the boards. Again caution must be taken. If the connectors are tight gently rock left and right until they are unplugged. Always grip by the connecting base. NEVER PULL CONNECTORS BY THE WIRES.

Once all connectors are cleared, gently remove the lens assembly. To do this gently grasp either side and lift it straight up, off of the mounting posts. Be careful not to touch the exposed glass lens or drop the assembly. Set assembly aside.

Remove the (5) screws securing the controller port assembly and surrounding thin metal shielding. Lift the thin metal shielding off and unplug the controller port assembly from the mainboard and remove.

Once the laser assembly, controller port assembly and thin metal shielding are removed a heavy metal plate remains covering the mainboard. Remove the (5) securing screws. Now gently lift the steel plate from the system and set aside.

CAUTION: Before handling the circuit board touch a piece of grounded metal to remove any static charge from your body. These components are static sensitive. Remove the (3) screws securing the rear edge of the circuit board and gently lift it from the case. Set the case aside.

To begin, flip the main board over (THE MOD CHIP IS INSTALLED ON THE BOTTOM OF THE MAINBOARD). Using the provided picture compare it to the board to identify the area in which the chip is to be installed.

The board is now ready to be soldered. To start you should have a fine tip, low temperature soldering iron. (15 watt is ideal) Using the solder provided quickly touch the iron and the solder onto the pad. Hold only for a second. When the iron tip is removed you should have a tiny ball of solder bonded to the pad on the board. All MOD chips come pre-wired and soldered so tinning the wires is not necessary. Place the wire onto the pre-soldered contact and touch it with the soldering iron. The solder should flow and the wire will bond to the pad. To complete the wiring, attach the other remaining wires to the indicated soldering pads. CAUTION: Due to the heat involved in soldering you must only hold the tip on the work for enough time to get the solder to flow. If too much heat is applied to the work it may damage the chip, lift the PCB trace or burn the insulation back on the wire. If the insulation for the MOD Chip wires burns back you must trim and re-solder. Too much insulation removed could result in the exposed copper touching other traces on the board. This is hazardous to the PSX unit.

Once all of the wires are attached, visually inspect the board to ensure that no exposed copper is touching any adjacent traces. You can now lay the MOD Chip on the board in a clear area where it will not be damaged.

Once you are pleased with the work, follow the above steps in reverse order to re-assemble the PlayStation.

Reconnect the unit to your power source and video outputs. Power up the Play Station. The chip will take a few seconds to initialize when playing imports or backups. If the unit is turned on and the white screen does not boot up within a few seconds shut the unit off immediately. Disassemble the PSX and start from the beginning to try and find the fault.
