Sony Playstation Repair Procedures

PSX 9000 series

Firstly check all the fuses for a continuity and when powered up the correct voltages. Have a frequency counter
and make sure the correct frequency is

displayed at the external oscillators. Also check the
voltage regulators for correct output.

The 9000 series is almost the same as the 7502. The problems found in the 7502 can be applied to the 9000


This board suffered from dry joints on the CPU 2 Meg RAM. The problem was that when the shield
ing was
screwed down tight it

would bend the board. The Memory was across the bend in the board. Then dry joints would form and when
powered up the PSX 900 series

would boot into a blank black screen.

• Blank screen at power up, check for ROM (IC102) write
s with scope (pin 125 of CPU) when reset button is
pushed. If static write then

replace ROM. If ROM writing data is OK then replace the CPU. Also check for CPU to memory writes (Pins 46
to 49 CPU). If ACK

writes are static or if nothing on scope the 2 Meg
ram could be faulty or have dry joints.

Replace 2 Meg
Memory, CPU or ROM.

• When powered up the machine keeps resetting, like if you have pressed the reset button. The PSU has a fault.

Replace PSU.

Optical Block problems

• No spin, No laser spot, Volta
ges ok.

CN702 pin12 should have 3.5v. If not Check Resistor near pin 12 for an
open circuit. If so then

replace. Also applies to SCPH 7502 models.

Optical Block problems NOTE!!!! Optimal RV703 position 11 o’clock

• No vertic
al movement or spin

Try replacing the OB then re
flow IC305, IC704 then replace also check S301

• CD in very fast spin, even at power on

flow IC704, IC305 or replace

• Jerking Laser movement

replace IC704

• Disk spins up then no change at

boot, disk then stops

Replace IC704

• Not loading, keeps pining at same speed then stops, starts again

IC303, IC305

• Will not read CD’s also clicks when reading

Replace OB and also IC704, IC305, IC706

• No OB movement no laser

Check the 3.5V rail,

if no then replace Q611 or check PS601 (fuse) or change
