The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.  During repair, pay attention to electrostatic break-down 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. 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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
