My logitech usb lighted keyboard developed an intermittent open at the entrance to the keyboard, inside the stress grommet. i opened it up and found the open,. however i am not sure i can do the splice since the wire there is so thin and i already broke the copper foilwrap. if i had a butt splice connector i could probably do it, i do not know if they make the butt connectors this small.i am worried if i try to get the insulation off of the broken red wire to splice, i will do more damage. i have plenty of usb cords and cheaper keyboards , so if i know at the usb connection to keyboard is a better place to do the fix, i will open it up further. speaking of keyboards, i spilt a cup of black, no sugar coffee on my wireless laser one, i flipped it and ran some fresh water into it, but a couple keys don't work., wondering if trying to pour water or rubbing alcohol into it may be worth a try ?
