This power supply is prone to failure due to little to no ventilation. So the capacitor cooks and vastly reduces its life span. However its worth replacing the single 420v 150µF cap providing the console powers on for a second. Or is making the buzzing noise. No power indicates a do-able, but more involved repair where supposedly you need to source a 4 pin diode package that is somewhat hard to get. Among other parts to replace. Noted in Solutions.
There is another version of the power supply. However the main control chip is directly under the 420v capacitor. Others have deemed them not worth repairing. I do not have access to one.
Known Issues
Capacitor Failure
Symptoms
- The console will produce a buzzing noise.
- The console will not power on or powers on for 5 seconds, then powers off.
Causes
- Poor heat dissipation causes the cap to fail.
Solutions
- Replace the 420v 150uF capacitor.
- If the PSU is completely dead. The repair might be more extensive. See "QS Tech" video in References.
Disassembly Notes
Pry at the sides of the plastic housing. Lifting to free the tabs holding it together. The tabs positions are indicated by the holes on the side of the plastic housing. See Figure A.
To remove the circuit board. You will need to remove some of the white Silastic glue in the corner opposite where the cable comes out. As well as near the capacitor itself. See Figure C.
You will need to remove the bottom plate covering the PCB. There are tabs on both the front and back you need to flow to remove the plate. Be aware of the thermal pads between the plate and PCB.
You could cut the leads to the capacitor and avoid removing the bottom plate if you wanted to save time. Not ideal though.
