Just now looking up what a pico fuse is. I didn't look for one of those the first time I checked. If it's green or blue, what symptoms am I looking for? Will it be swollen, burnt, discolored? You say it will be near the input? That makes sense since only that input doesn't work.
Also googling the term "pico fuse" will most PCB's have it labeled something like "FU35" or the like?
