So, I am using the Pi on a robotics project and, while doing so, bumped my +15V source (wall transformer, rated for 400mA and 15V) into one of the pin inputs. It touched for <0.5s, but now connecting the monitor and power gives a blank screen (not the test screen, just blank, and monitor goes to sleep after 5s) and the red and green LEDs are solid, not flashing.

Did I blow the Pi, or will it possibly work after I let the polyfuse settle for 4-5 days?

Thanks

I reckon you have a dead Pi.

The 15V was inserted directly into the Pi, it did not go through the polyfuse, so the polyfuse will not have given the limited protection it provides.

If you have a meter (carefully) measure the voltage at the Pi 5V pin. If it is 5V then the polyfuse has not operated.
