I’m sorry to hear about the trouble. If the power is good, then you’re right that the chips should be the next suspect. I’m not sure what could have happened– could be power surge related, for example.
The one other thing that you might try is to reprogram the clock, and see if it will accept that, either with an AVR ISP programmer or an FTDI type interface. (Since you were thinking of reprogramming it, I suspect that you have one or both of these interfaces available.)
Otherwise, if you’re willing to, I’d ask that you return the chip set to us so that we can test them here, figure out what happened, and replace/reprogram/return them in working condition– please contact our store directly by e-mail or with the contact form.
