    1. Check the area of your repair for unsoldered or poorly-solderedconnections. Check the entire board surface for solder splashesand bridges.

    2. Check the interboard wiring to ensure that no wires are"pinched" or contact high-wattage resistors.

    3. Look for unauthorized replacement parts, particularlytransistors, that were installed during a previous repair. Pointthem out to the customer and recommend their replacement.

    4. Look for parts which, through functioning, show obvious signsof deterioration. Point them out to the customer andrecommend their replacement.

    SAFETY CHECK-OUTAfter correcting the original service problem, perform the following safetychecks before releasing the set to the customer.

    5. Check the B+ voltage to see it is at the values specified.6. Flexible Circuit Board Repairing

    Keep the temperature of the soldering iron around 270Cduring repairing.

    Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times).

    Be careful not to apply force on the conductor when solderingor unsoldering.

  • 4This appliance is classified as a CLASS 1 LASER product.The CLASS 1 LASER PRODUCT MARKING is located onthe rear exterior.

    Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.

    The following caution label is located inside the unit.

    The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the prin
