C64 Keyboard restoration. Revive key response
About this video
Why do some Commodore 64 keys stay dead after an isopropyl clean? The maker argues that over-cleaning the rubber pad and contacts does harm, and adds a further step to revive them.
Good to know: Isopropyl alcohol is flammable and needs ventilation. Follows an earlier video on opening the keyboard.
Why watch it
Open this one if an alcohol clean has already been done and some keys, such as A, 2 and return, still do not respond. The cleaning itself is in an earlier, linked video.
