[oopic] OOPic-R board problem

I have an OOPic-R board with firmware C.1.1+. After applying the power
to the board, the power good LED does NOT light up. Connect through RS-
232 with PC does not show any response. But pushing the 3 little
buttons on the board do light up the LED on top of it. Is the board
defective? How I can check if the OOPic is working ok?
