Zedboard power up fail

Hi sir,

When I power on the Zedboard, the LD13(power) doesn't light and LD0 ~ LD7 all RED.

The only action was that I shorted the 3.3V of J18.
After that, the Zedboard seems crashed?

Could I reset it by myself?

Hi Blake,
Unless it is under the warranty period (60 days) we cannot accept it and offer a replacement.
If you wish to send it to a 3rd party for diganostics please feel free, however that will most likely cost more then the worth of the board. My suggestion would be to just replace it with a new one.

Hi Josh,
Unfortunately, I think we have exceeded the warranty period.
Let us go back to rework by ourselves.
As you previous mentioned, maybe we can rework IC27 (MAXIM 15021).
First, I measure the C339 and it always 0V no matter I switched the jumper to 2.5V or 1.8V.
Therefore, how to measure IC27 and make sure it was shorted?
