    1. REMOVAL OF ANODE CAP

    Read the following NOTEDitems before starting work.

    After turning the power off there might still be a potential

    voltage that is very dangerous. When removing the

    Anode Cap, make sure to discharge the Anode Cap'spotential voltage.

    Do not use pliers to loosen or tighten the Anode Cap

    terminal, this may cause the spring to be damaged.

    REMOVAL

    1. Follow the steps as follows to discharge the Anode Cap.

    (Refer to Fig. 1-1.)

    Connect one end of an Alligator Clip to the metal part of

    a flat-blade screwdriver and the other end to ground.While holding the plastic part of the insulated screwdriver,

    touch the support of the Anode with the tip of the

    screwdriver.

    A cracking noise will be heard as the voltage is discharged.

    Flip up the sides of the Rubber Cap in the direction of the

    arrow and remove one side of the support.(Refer to Fig. 1-2.)

    3. After one side is removed, pull in the opposite direction to

    remove the other.

    NOTE

    Take care not to damage the Rubber Cap.

    INSTALLATION

    1. Clean the spot where the cap was located with a small

    amount of alcohol. (Refer to Fig. 1-3.)

    Location of Anode Cap

    NOTE

    Confirm that there is no dirt, dust, etc. at the spot where

    the cap was located.

    2.

    3.

    Arrange the wire of the Anode Cap and make sure thewire is not twisted.

    Turn over the Rubber Cap. (Refer to Fig. 1-4.)

    4. Insert one end of the Anode Support into the anode button,

    then the other as shown in Fig. 1-5.

    5.6.

    Confirm that the Support is securely connected.Put on the Rubber Cap without moving any parts.

    NOTE

    REMOVAL AND INSTALLATION OFFLAT PACKAGE IC

    Some ICs on the PCB are affixed with glue, so be

    careful not to break or damage the foil of each IC

    leads or solder lands under the IC when removing it.

    NOTE

    Masking is carried out on all the parts located within

    10 mm distance from IC leads.

    Fig. 2-2

    NOTE

    Do not add the rotating and the back and forth

    directions force on the IC, until IC can move back andforth easily after desoldering the IC leads completely.

    When IC starts moving back and forth easily after

    desoldering completely, pickup the corner of the IC using

    a tweezers and remove the IC by moving with the ICdesoldering machine. (Refer to Fig. 2-3.)

    NOTE

    When the IC leads are bent during soldering and/or

    repairing, do not repair the bending of leads. If the

    bending of leads are repaired, the pattern may be

    damaged. So, be always sure to replace the IC in this

    case.

    Finally, confirm the soldering status on four sides of the

    IC using a magnifying glass.

    Confirm that no abnormality is found on the solderingposition and installation position of the parts around the

    IC. If some abnormality is found, correct by resoldering.

    5.Solder temporarily

    INSTALLATION

    Take care of the polarity of new IC and then install the

    new IC fitting on the printed circuit pattern. Then solder

    each lead on the diagonal positions of IC temporarily.

    ELECTRICAL ADJUSTMENTS

    1.

    Read and perform these adjustments when repairing the

    circuits or replacing electrical parts or PCB assemblies.

    CAUTION

    Use an isolation transformer when performing any service on

    this chassis.

    Before removing the anode cap, discharge electricity because

    it contains high voltage.

    When removing a PCB or related component, after

    unfastening or changing a wire, be sure to put the wire back

    in its original position.Inferior silicon grease can damage IC's and transistors. When

    When you exchange IC and Transistor for a heat sink,

    apply the silicon grease (YG6260M)on the contract

    section of the heat sink, Before applying new silicon

    grease, remove all the old silicon grease. (Old grease

    may cause damages to the IC and Transistor.)
