This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.

ADJUSTMENT
� L.P.S. initial position adjustment procedure
1. Connect the changer to the HEAD UNIT (H/U). 2. While holding the magazine eject button of the changer, press the reset button of the H/U. 3. After about 3 seconds, release the magazine eject button. 4. Press the SRC button of the H/U to enter the CD-CH mode, and the H/U's display section indicates �E-88�. 5. Move the mechanism deck to around the 1st stage by pressing the DISC- or DISC+ button. 6. Insert the adjustment tool (W05-0635-00) into the tool hole on the changer mechanism. 7. Then press the DISC+ button to move the mechanism deck until the mechanism's slider hits the adjustment tool. 8. When the motor locks (stops), press the REPEAT key of the H/U. When the REPEAT key is pressed, the mechanism moves automatically to the 1st stage and the initial position adjustment completes. (The data is written in the EEPROM at this time.)
W05-0635-00
� Caution : Note on IC8 (EEPROM)
Be sure to use the W05-0869-00 when replacing the EEPROM. IC8 stores the digital servo data of the pickup servo. Therefore, if the EEPROM does not store servo data, ERROR76 (E-76) will indicate the H/U�s display section at the moment CD is played.
