Good guy on the Internet Ken Guest gave me a NC100 many years ago. I since broke it by plugging in the wrong power supply by accident (Sinclair and Amstrad gear from the era usually used a negative centre power supply connector where most everyone else did the opposite).
This results in a popped surface mount fuse. There is a very naughty fix described here where you just solder a strand of wire (fuse wire if you can be bothered) across the contacts.
Because I am an oaf with clown hands and sausage fingers, I managed the soldering job but broke the LCD ribbon cable when reassembling it. Luckily I found a Replacement ribbon cable from Farnell which is now installed and working:
I picked up a spare ribbon cable in case I want to open the thing up again and put in, you know, a real fuse. The cables I got are at least 5cm longer than the original, so future maintenance work should be a little easier. Contacts for the CR2032 lithium cell also got an alcohol scrub while I was in there (if you don't have this, the unit refuses to turn on).
