power supply mistake?!?

[mburns1339]

Any help is greatly appreciated, I have a raspberry pi, I believe it's an A model, one of the first ones, and it was running great off USB power supply, and then I found a power brick that I thought might work, so I plugged the tip into the black power supply to see if it would fit (without the other end plugged into an outlet). It froze my pi, and when I tried rebooting it, it wouldn't come back on. The red power light comes on but nothing else.

Did I just fry my pi accidentally?? Please help!

thanks!

Is there a label on the power brick? If so, please report back with the contents of the label, which ought to include the output voltage specification.

You could also try re-imaging your SD card (or putting a new image on a new card) and trying that.

What do you mean by "tip"?
What is "black power supply"?

Yikes, it was actually the black audio jack port (next to the yellow video port). I feel so dumb. But why would plugging a power port (that wasn't plugged into an outlet) into the audio jack crash my pi?

thanks again, I feel so dumb

the wall wart says input 100-240VA, output 12V

Ok, but if it wasn't plugged into the wall then there should be no voltage present on the plug you put into the Pi. As far as I know, all the pins on the AV plug are buffered, so they can survive a short to ground.

Unless you had recently (in the preceding few minutes) plugged the power brick into the wall. In which case there may have been some residual charge in an internal capacitor inside the power brick.

Try re-imaging the SD card. All the stuff to make the Pi work is on the card. You may have merely corrupted a file on the card.

How long had it been since the power supply was powered on? The capacitors in the power supply can hold a charge for several minutes after unplugged.

not sure, I reformatted my sd card, but no luck. The power light comes on, but that's it, it wont boot or anything.
