instrument cluster problems

[okczy21]

my speedo and tach isnt working, sometimes it does work if i hit the plastic, the needles will pop up like they were stuck or something, i installed gauges and this problem occurred, it doesnt look like any fuses are blown, does anyone know anything about these bmw clusters, im giving up hope on this site, nobody can seem to answer my question

could be a loose connection

i took it apart and i thought i put it back together as tight as i could because i thought it was a loose connection
