During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick- up block. Therefore, when checking the laser diode emission, observe from more than 30cm away from the objective lens. Before Replacing the Optical pick-up Block Please be sure to check thoroughly the parameters as per the ÒOptical pick-up Block Checking ProcedureÓ (Part No. : 9-960-027-11) issued separately before replacing the optical Pick-up block. Note and specifications required to check are given below. ¥ FOK output : IC501 !ª pin When checking FOK, remove the lead wire to disc motor. ¥ S curve P-to-P value : 0.9 Ð 1.5Vp-p IC501 #Á pin. (Connect pin !ª of IC501 (TP880) and 3 of IC501 (GND) with a jumper wire). When checking S curve P-to-P value, remove the lead wire to disc motor. ¥ Adjusted part for focus gain adjustment : RV503 ¥ RF signal P-to-P value : 0.85 Ð 1.15Vp-p ¥ Traverse signal P-to-P value : 1.0 Ð 2.6Vp-p ¥ The repairing grating holder is impossible. ¥ Adjusted part for tracking gain adjustment : RV502
