The pix "boots", but nothing appears on the Hyper Terminal, and the leads in the front don'tlight up.The leads light up half a second when I start and when I stop the pix...When I close it, I have 4 little ASCII squares that appear on Hyper Terminal ...

I am in despair.I have a PIX 515, and I think its dead. Since a bought it used, I worked on it only 5 times.I put the IOS 6.2 to use it, and everything was going perfectly. Suddenly, it made an error of the type "Watch dog failure".I had to reboot. (...
