A while back, I was connecting my POD to my computer, and my hand slipped and I plugged the USB cable into the pedal port. After that, my PODxt will do this every time I power it up.
It works for a few seconds, then crashes. If I turn it back on immediately, it stays frozen like this, but if I give it a while it'll function again for a few seconds, then crash again.
I've looked around on the board, and I don't think any of the caps or resistors look blown.



These are shots around the USB and pedal ports, and the power supply. I'm assuming anything affecting functions would be in that general area.
