    I've had this cutter connected up through a serial to USB adapter for a few years as the USB didn't work, I wanted to get it directly through the USB so decided to buy a new port and do a repair.

    After getting to the port though it seems a previous owner has already attempted it and his solders wasn't great and its possibly shorted the board?

    The cutter is still working fine through the adapter but I'm just wondering if it would still be repairable or if I'd be best leaving it alone.

    hiks,
    that certainly is sloppy soldering, but, typically a usb problem is not the port itself.
    it is normally the ic (a semiconductor) that fails, from a static discharge.

    usb connectors do go bad, but i wouldn't bet on this one

    someone who does electronic repairs, (tv repair, vcr repair, stereo repair) can do this for you snd clean that board up

    I've done alot of board level repair and that photo isn't alarming. The burn marks look bad but sometimes that happens. All that solder can be removed and redone but it if it still doesnt work netsol is right about IC... and believe me, replacing an IC is MUCH harder then that lil ol port. 9 times out of ten if you consider replacing an IC see if you can just buy a new board.

    Interesting, thanks for the replies.

    I'll take it to TV repair place as suggested and see if he can do anything with it.

    I doubt I'd be able to replace the board as it's an old FC5100 series, it's a workhorse though and I do want to keep it around.

    Good idea.

    I worked at a computer repair shop that also repaired TVs... and I got 90% of my board-level repair experience on the TV side of things.
