Be carefull when taking advice to slap or bang your instrument binacle, remember they are only made of plastic,
If you have checked the cable connection on rear of the speedo and you said its ok, the next part is to check that the square nipple end that protrudes out of the near side domed cap in the middle of the wheel,there is a small circlip which holds the cable end,if this is still intact check that the nipple end has not rounded off should be 4 flats with a small groove were clip locates, if it has rounded it can be drilled with a small drill and and put a small pin through (a panel pin ) for example.
To remove said cable from wheel if you look to the back of the wheel you will see were cable enters there is also a little bolted bracket 10mm note the possition its located then you will be able to draw it out from the centre of the wheel to ease drilling refit in reverse order.if all else fails your cable has broken somewere.
