Thanks James for lots of useful info.

I further inspected the board and found out that Q5, R34, and R35 are
blown. I didn't notice these before. They may have been fried after I
installed the fuse. For Q5, I am planning to find one from radio shack.
But, I need the resistance values on R34 and R35. Would you by any
chance have this numbers?

Thanks,
PB
