Have the Full Service manual but no reference is setting Pots SFR401 and SFR402, these are used for CD Elevator optical sensing
SFR402 is for the I.R Led current and SFR401 a schmitt trigger level from the optical sensor
Their is also a 4 Pin test connector that's involved, CON8 as its connected to these points
Nothing is mentioned in the service manual at all.
This Optical sensor is used to set up the position of the CD selector to correctly to select the CD..
Can any one Help..
Sony is a total waste of Time here.
Thanks
