I have tried the recommended fix of adding electrical tape onto the post to boost the connection to the microswitch, but still making the clicking/grinding noise and displaying "welcome" and "eject", ven though no disc is in place. How can I fix it?

Hi,
The mech is out of alignment.
As far as i know...there was no start up bug on this model.
I have been on a Sony service traing course for this model...and nothing was mentioned about this.
Sorry but you will need to take it to a suitable repair shop.
I have repaired many of these units with this fault.
It just needs the mech re-aligning.
I hope this has been some help.
