Unique Capacitor Value Found In Power Supply

A friend of mine and a computer technician brought me a play station that was damaged by a step down voltage converter. He knew how to hook up a play station that runs on 110 AC volts to a step down converter and get his play station up and running. For some reason, the transformer blew and damaged the play station.

The power supply is inside the play station housing.




In order to get to that power supply, screws have to come off.

All the screws are in the back of this device. They are very easy to come off to exposed the inside power supply.

Once the top cover came off, I was able to see the top of the power supply.

Just unplug it from the main play station and if you flip it to the other side, you will see another screw that needs to come off to expose the power supply.

The moment the top cover of the power supply was off, I was able to see inside and look for the damaged caused by the faulty step down converter.

Can you see the damage? The first things that caught my eyes were the plugged capacitors.




I have seen it before and hope to see it here that no other parts are damaged.

Here is a closer look to the damaged capacitors. There was a little bit of capacitor juice inside the power supply and that is why, gloves were put on to avoid any contact with such juice.

Once I took the protective white cover of the capacitors, I was able to see the value of it. To be honest with you, it is the first time I see such value of capacitors.

After cleaning all the power supply and checking the primary and secondary section I was able to determine again that the only damage were these two capacitors. The fuse was intact as well.

Lucky me, I had capacitors from an old play station that has issues reading the hard drive; I was able to use those on this device

I connected it to a new 220-110 AC volts step down converter and I was able to turn it on.

    Nice repair! Although this Playstation is now as new but was killed by the Step-down transformer it seems to me that examining the cause of the defective source which is the now failing step-down transformer should be in this article too. This way making sure it never happens to other Playstation consoles in future again.

      Albert: thanks. I will keep that in mind for the coming repair article. the step down transformer was really in bad shape...dirty, loose wires..etc.

    I like your term 'capacitor juice', brought a good smile! Good fix as usual! Yes, indeed strange valued capacitors! Good luck that you had them in stock!

      Parasuraman: thanks man. yes I was lucky to find them..that is a a good idea to keep capacitors with strange value in the shop and ever throw them away.

    Strange, those capacitors seem to suggest the unit can run on 220V

      Anwar: yes, I am guessing that somone else was messing with this machine and he added these strange value to the machine.

    Very good, Waleed. Once again problems with (probably) bad Chinese el-caps. However, I suspect that the issue was not with the step-down voltage converter itself. It seems to be just a coincidence: the el-caps were already bad at that moment. The voltage coming from the voltage converter (perhaps not so deviated from the nominal value) could have increased the chance of the problem, affecting these two components perhaps already at the edge of the abyss. I argue this based on the fact that no other component was damaged (fuse, diodes, switching transistor etc.).

      Henrique: thanks. the transformer was in bad shape..dirty, rusty, loose wires all over..even the main power plug was not good. I should have added a photo of the transformer to show you the damage on it. the voltage on it was not steady and I believe it could damage such devices.
