Cyclone 2 FPGA Starter Board Issue

Hello, My Cyclone II FPGA Starter Board seems not to work when I program it through the USB blaster cable. When I download a sof file, I see the blue led flashing. But simply my programs aren't...

No. If you are loading the same .sof you used when the board was ok, there's no problem with pin assignment. I simply wondered if you had recompiled the demo design and had made a mess with pins.

It's very strange you damaged the board when opening the case with a ESD. I've been using fpga boards without cases for more than 10 years, sometimes I even caused ESD (with the spark!) but I never damaged a board.

More probable is the event of a short circuit or any other mechanical damage in removing the board (especially if you applied mechanical stress or torsion because of plastic clips or similar)

I'd suggest you create a simple Quartus project which drives LEDs and 7-seg pins in a know sequence. This can be done in half an hour and will immediately tell you if the hardware is ok.
