Need help replacing capacitor

The Ouya console came with an UK adapter, but I needed the EU adapter. I had an other adapter laying around with the same specifications, but unfortunately the output was 12AC instead of 12DC. There was a bad smell and even before I could use it, the console is broken. It still boots, but the screen freezes all the time.

Opening the console the problem became clear, a capacitor is broken. I would like to know which capacitor is used next to the powerjack (see picture), so I can replace it. In the picture I already removed the capacitor from the board but the markings on the capacitor are unreadable.

I contacted the official support but with no success so far. Thanks in advance and best regards.

Big difference between ac and dc, surprised it worked at all. Is the component unreadable due to damage or due to its size?

It's unreadable due the damage.

I took some pictures about my board. Unfortunately there are no visible markings on the component... (Are you sure it's a cap?...)

(Maybe someone with a different board will have better luck.)

Thank you for the effort, it's much appreciated.
It might also be a resistor. I don't have much experience with smd components or even with electronics.

Have you tried contacting OUYA support? I don't know if they'll tell you what it is but may be able to help in another way.

I'm still awaiting a response to my mail.

It looks like a 1210 model ceramic capacitor. Probably 10uf at 25v. Designed to act as a filter to regulate any noise coming down the 3-4 feet of DC wire. http://www.jameco.com/1/3/10uf-ceramic-capacitor for a reference.

Although just to be on the extra safe side. Wait for Ouya to confirm.

Thank you for the reply. I will check the local electronics store for a replacement.

Suprised the Ouya didn't have a fuse that blew first like with a GBA.

They didn't have SMD components, but I tried it with an other capacitor without success. The Ouya doesn't boot up any more at all, so I guess I will be giving up. If the official support would still give an answer, I'll share it in this topic.

Thank you all for the interest and help.

Sorry it didn't work out.

You tried with another capacitor? Was it an electrolytic? Some of the eletrolytic capacitors have a higher ESR then polymers and ceramics. Which could add more noise into your power circuit. And yeah, SMD capacitors you typically have to get from Chinese vendors as your big named houses like digikey or mouser will only sell them to you in packs of 50.

Yes, it was an electrolytic capacitor.

More surprised about some guys that thinks that 12 vdc is the same tan 12 vac. Engineers can´t protect devices against stupidity.

Yes, that's how it went...

If it was an electrolytic he could of got the polarity wrong.
This would def. keep the rest of the board from getting power.

Saito,
try reversing the capacitor.

Also, I wouldn't be too hard on OUYA support.
There are not many companies out there that would give out that info.
In OUYA's case i'm guessing the boards in these are NVIDIA T3 reference boards so OUYA inc. might not even know what the components are themselves.

I should warn people that reversing an electrolytic cap since it is polarized can produce hazardous results such as explosion. You do have to worry about polarity where with ceramics you don't since they are used for filtering. If you have to use a electrolytic as a substitution and you understand that you are altering the ripple and frequency since you may not have an oscilloscope to see the changes then the negative on an electrolytic will go to your ground.

If its a filter you could just try bridging the connection...what do you have to loose?
