Measures
Repair or replace the cas-
sette base if it cannot move
vertically.
Check if the drive gears to lift
up the cassette base rotate
smoothly or have no exces-
sive load. And apply the
grease to the frictional parts
and repair the related parts
so that they can rotate
smoothly.
Clean the terminal of the fol-
lowing wire connectors and
reconnect the connectors. If
there is no continuity, replace
the wire. • PF lift motor - PF
main PWB
