    Some pictures would be almost essential.

    I'd concentrate on checking rectifier diodes and mosfets. Less likely to be a mosfet if the fuse doesn't blow.

    Does it make any sound (like a click) when you turn it on?

    I had a non-working adaptor that had a lot of flux on the board, came back to life when I cleaned all the flux off; maybe what really happened is that I cleared some whiskers.
