Please can someone advise me regarding a defect on a Kenwood 3 disc player?
It started showing no cd on the front display when this was obviously wrong.
I have replaced the KSS 213B laser unit but with no effect as it still
displays the message.
Whilst I am not an expert I am too stubborn to give in to a plastic box of
wires.
Regards,
Chris

Did you remove the solder short on the new pickup?

Make sure that the disc is spinning once it is accessed by the laser.
If it is not, it will act as no disc has been inserted.

If there was a solder short on the cable of the new pickup, did you remove
it?

The solder-short on a KSS-213 is on the little PC board part of the pickup.

1. As advised, if the pickup has a solder short, it must be desoldered to
allow the pickup to operate. This solder short is designed to protect the
pickup electronics from electrostatic discharge damage during shipment, but
must be remove to allow normal operation.

2. Does the pickup use a ribbon cable to connect it to the player? Sometimes,
breaks can develop on the conductors which can cause a malfunction.

You won't have to worry about recalibration of this pickup as it is a Sony
part. Sony pickups are usually precalibrated at the factory. A lot of
manufacturers, including Kenwood and Onkyo, have used Sony pickups in their CD
players. - Reinhart
