SERVICING NOTICES ON CHECKING

1. KEEP THE NOTICES

2. AVOID AN ELECTRIC SHOCK

As for the places which need special attentions, they areindicated with the labels or seals on the cabinet, chassisand parts. Make sure to keep the indications and noticesin the operation manual.

There is a high voltage part inside. Avoid an electricshock while the electric current is flowing.

3. USE THE DESIGNATED PARTS

The parts in this equipment have the specificcharacters of incombustibility and withstand voltage forsafety. Therefore, the part which is replaced should beused the part which has the same character.Especially as to the important parts for safety which isindicated in the circuit diagram or the table of parts asa mark, the designated parts must be used.

6. AVOID AN X-RAYSafety is secured against an X-ray by considering aboutthe cathode-ray tube and the high voltageperipheral circuit, etc.Therefore, when repairing the high voltage peripheralcircuit, use the designated parts and make sure notmodify the circuit.Repairing except indicates causes rising of highvoltage, and it emits an X-ray from the cathode-ray tube.

4. PUT PARTS AND WIRES IN THE ORIGINALPOSITION AFTER ASSEMBLING OR WIRING

There are parts which use the insulation material suchas a tube or tape for safety, or which are assembled inthe condition that these do not contact with the printedboard. The inside wiring is designed not to get closer tothe pyrogenic parts and high voltage parts. Therefore,put these parts in the original positions.

5. TAKE CARE TO DEAL WITH THECATHODE-RAY TUBE

In the condition that an explosion-proof cathode-raytube is set in this equipment, safety is secured againstimplosion. However, when removing it or serving frombackward, it is dangerous to give a shock. Takeenough care to deal with it.

PERFORM A SAFETY CHECK AFTERSERVICING

7.

Confirm that the screws, parts and wiring which wereremoved in order to service are put in the originalpositions, or whether there are the portions whicharedeteriorated around the serviced places serviced ornot.Check the insulation between the antenna terminal orexternal metal and the AC cord plug blades. And be surethe safety of that.

(INSULATION CHECK PROCEDURE)

1.2.

3.

4.

Unplug the plug from the AC outlet.Remove the antenna terminal on TV and turn on theTV.Insulation resistance between the cord plug terminalsand the eternal exposure metal [Note 2] should bemore than 1M ohm by using the 500V insulation resis-tance meter [Note 1] .If the insulation resistance is less than 1M ohm, theinspection repair should be required.

[Note 1]

If you have not the 500V insulation resistance meter,use a Tester.

3. REMOVAL OF ANODE CAPRead the following NOTED items before starting work.

After turning the power off there might still be a potentialvoltage that is very dangerous. When removing theAnode Cap, make sure to discharge the Anode Cap'spotential voltage.Do not use pliers to loosen or tighten the Anode Capterminal, this may cause the spring to be damaged.

*

*

REMOVAL

1. Follow the steps as follows to discharge the Anode Cap.(Refer to Fig. 3-1.)Connect one end of an Alligator Clip to the metal part of aflat-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 theScrewdriver.A cracking noise will be heard as the voltage is discharged.

Flip up the sides of the Rubber Cap in the direction of thearrow and remove one side of the support.(Refer to Fig. 3-2.)

NOTE

Take care not to damage the Rubber Cap.

INSTALLATION

1. Clean the spot where the cap was located with a smallamount of alcohol. (Refer to Fig. 3-3.)

Location of Anode Cap

NOTE

Confirm that there is no dirt, dust, etc. at the spot wherethe 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. 3-4.)

4. Insert one end of the Anode Support into the anode button,then the other as shown in Fig. 3-5 .

5.6.

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

PREVENTIVE CHECKS AND SERVICE INTERVALS

The following standard table depends on environmental conditions and usage. Unless maintenance is properlycarried out, the following service intervals may be quite shortened as harmful effects may be had on other parts.Also, long term storage or misuse may cause transformation and aging of rubber parts.

NotesTime

Parts Name

CLEANINGNOTE

After cleaning the heads with isopropyl alcohol, do notrun a tape until the heads dry completely. If the headsare not completely dry and alcohol gets on the tape,damage may occur.

1. AUDIO CONTROL HEAD

Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol and clean the audio control head bywiping it horizontally. Clean the full erase head in thesame manner. (Refer to the figure below)

2. TAPE RUNNING SYSTEM

When cleaning the tape transport system, use thegauze moistened with isopropyl alcohol.

3. CYLINDER

Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol. Hold it to the cylinder head softly.Turn the cylinder head counterclockwise to clean it (inthe direction of the arrow). (Refer to the figure below)

NOTE

Do not exert force against the cylinder head. Do not movethe chamois up or down since this can damage the head.Always use a piece of chamois for cleaning.

NOTE FOR THE REPLACING OF MEMORY IC

If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken toensure correct data settings while making reference to TABLE 1.

NOTE

Turn the unit on and let it warm up for at least 30minutes before performing the following adjustments.Place the CRT surface facing east or west to reduce theterrestrial magnetism.Turn ON the unit and demagnetize with a Degauss Coil.

Tighten the screw for the magnet. Refer to the adjustedCRT for the position. (Refer to Fig. 5-1)If the deflection yoke and magnet are in one body,untighten the screw for the body.Receive the green raster pattern from the color bargenerator.Slide the deflection yoke until it touches the funnelside of the CRT.Adjust center of screen to green, with red and blue on thesides, using the pair of purity magnets.Switch the color bar generator from the green rasterpattern to the crosshatch pattern.Combine red and blue of the 3 color crosshatch patternon the center of the screen by adjusting the pair of4 pole magnets.Combine red/blue (magenta) and green by adjusting thepair of 6 pole magnets.Adjust the crosshatch pattern to change to whiteby repeating steps 6 and 7.

Receive the green raster pattern from color bargenerator.Adjust the pair of purity magnets to center thecolor on the screen.Adjust the pair of purity magnets so the color at theends are equally wide.Move the deflection yoke backward (to neck side)slowly, and stop it at the position when the wholescreen is green.Confirm red and blue colors.Adjust the slant of the deflection yoke while watching thescreen, then tighten the fixing screw.


Receive the crosshatch pattern from the color bargenerator.Combine red and blue of the 3 color crosshatch patternon the center of the screen by adjusting the pair of4 pole magnets.Combine red/blue (magenta) and green by adjusting thepair of 6 pole magnets.

be sure to check the parts in the INFORMATION FOR USING THE DECK PARTS (OVD-5): 09-986-269-20O

for the repair. Because if you use wrong parts, the deck or tape will be damaged.
