Hello,

You did not mention what CD player the pickup is in, but a rapid fire
of the lens like that is not likely to be the pickup. It is more likely
to be a driver IC problem or a clock failure.

Can any one help me with my CD player? It's a Sony component CD player
that uses KSS-240 pickup. My problem is, as soon as the player is
powered on, the lens head will be immediately starting whacking up and
down, something like machine gun fires. The objective lens overshoots
and hits, making a sound somewhere like 10hz beating/whacking sounds.
It won't stop until powered off. Does anyone know how I can fix this?

Thanks a lot,

SY
