Keyboard port repair.

One of the most common things to go wrong is that the mouse and joystick ports the malfunction when solder points break.


Keyboard such as this one of easy to fix..

Turn the keyboard upside down and remove all the screws.. You will have to remove the plastic sticking sheet to gain access to a lot of the screws.

If done really carefully you can normally dismantle without the "cups" falling off, though if they do , no worries.

Notice however on the PCB that 2 of the cups are missing by default. So if your cups fall off then you need to know which 2 are supposed to be missing else you will spend hours looking for 2 cups which were not there in the first place! This is all too common!!

I decided to put all the screws in a small pot, that way I can lose the whole lot in one go rather than the odd one or two :)

The plastic keys as a whole got left to soak in warm washing up water and given a good clean with a soft brush.

The Mouse/Joystick ports normally break over time, so a must to resolder these pins even if they look ok.

All assembled back together and looks like its just come off the production line. Not bad for a 25 year old item :-)
