SAFETY PRECAUTIONS

  • 1. The design of this product contains special hardware and many circuits and components specially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Service should be performed by qualified personnel only.
  • 2. Alterations of the design or circuitry of the product should not be made. Any design alterations or additions will void the manufacturer's warranty and will further relieve the manufacturer of responsibility for personal injury or property damage resulting therefrom.
  • Many electrical and mechanical parts in the product have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage.

wattage, etc. Replacement parts which have these special safety characteristics are identified in the Parts List of Service Manual. Electrical components having such features are identified by shading on the schematics and by (Δ) on the Parts List in the Service Manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or other hazards.

4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of electric shock and fire hazard. When service is required, the original lead routing and dress should be ovserved, and it should be confirmed that they have been returned to normal, after re-assembling.

WARNING

  • 1. This equipment has been designed and manufactured to meet international safety standards.
  • 2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.
  • 3. Repairs must be made in accordance with the relevant safety standards.
  • 4. It is essential that safety critical components are replaced by approved parts.
  • 5. If mains volage selector is provided, check setting for local voltage.

PURITY, CONVERGENCE AND WHITE BALANCE

★ The locations of SERVICE SWITCH, SCREEN VR, CUT-OFF VR and DRIVE VR are described in the ALIGNMENT LOCATION of SERVICE ADJUSTMENT or the SCHEMATIC DIAGRAM.

PICTURE TUBE

The picture tube is a precision in-line gun type. For this picture tube, dynamic convergence is carried out by a precision deflec-tion yoke which eliminates the use of convergence yoke and convergence circuit. The adjustment of picture tube is therefore made easier as only the adjustment of static convergence by using magnets is enough. The deflection yoke and purity/convergency magnets assembly has been set at the factory and requires no field adjustments. However, should the assembly be accidentally jarred or tampered with, some or all adjustments may be necessary.

COLOUR PURITY & VERTICAL CENTRE

Loosen yoke retaining screw (Fig. B-1). With a sharp knife cut between the picture tube and the wedge. Remove wedges completely and clean off dried adhesive from the picture tube. PAINT is used to lock the tabs of the purity/convergence magnet assembly in palce (Fig. B-1). The paint must be removed with the end of a screwdriver before any adjustments are attempted.

(As to models equipped with a magnet locking ring, beforehand loosen it.)

  • 1. Select no signal UHF channel. (or Display a monochrome pattern)
  • 2. Let the purity tab come in line horizontally as is hown in Fig. B-2. A long tab should be in the same direction as the other short tab.
  • 3. Move the yoke slowly backward.
  • 4. Turn the GREEN CUT-OFF VR to maximum and the RED and BLUE CUT-OFF VRs to minimum. Then adjust the SCREEN VR so that the green band can be seen best (Fig. B-3)
  • 5. Rotate the two tabs in the opposite directions and with them kept at an angle, together in either direction so that the green band is centered on the picture tube.
  • 6. Check the vertical centre position by displaying a horizontal line. (Select the CUT-OFF SERVICE SWITCH from N to S and a HORIZONTAL LINE will appear.) Unless correct, bring it to the nearest centre by rotating the two tabs, kept at an angle, together in either direction. (Fig. B-4)
  • 7. Repeat steps 5 and 6 alternately until the green band and the vertical centre come to the centre.
  • 8. Move the yoke slowly towards the bell of the tube so that the whole surface of the picture tube is filled with a green pure raster.
  • Turning RED or BLUE CUT-OFF VR to maximum and GREEN CUT-OFF VR to minimum, make sure of a red or blue pure raster.
  • 10. Secure yoke retaining screw (do not install wedges at this time).

(As to models equipped with a magnet locking ring, secure it and keep six magnets from moving even if it is touched slightly.)

Page 10
STATIC CONVERGENCE & DYNAMIC CONVERGENCE

  • Connect a crosshatch generator to the input terminals and adjust BRIGHTNESS and CONTRAST control for a distinct pattern.
  • Adjust the convergence around the edges of the picture tube by tilting the yoke, up-down and left-right, and temporarily in-stall one wedge at the top of the voke. (Fig. B-2, 8, 9)
  • Rotate the front pair of tabs (four pole convergence magnet) as a unit to minimize the separation of the red and blue lines around the centre of the screen. To adjust the convergence of red and blue, vary the angle between the tabs. (Fig. B-5)
  • 4. Rotate the rear pair of tabs (six pole convergence magnets) as a unit to minimize the separation of the magenta (R/B) and green lines. (Fig. B-6)
  • 5. Adjust the spacing of the rear tabs to converge the magenta and green lines.
  • 6 Apply paints to fix six magnets.
  • (As to models equipped with a magnet locking ring, tighten it.) 7 Bemove the wedge installed temporarily on the voke.
  • 8. Tilting the angle of the yoke up, down and sideways, and adjust the yoke so as to obtain the circumference convergence. (Fig. B-8, 9)
  • 9. Insert wedges to the position as shown in Fig. B-10 to obtain the best circumference convergence.
  • 10. The wedges have a backing of double sided adhesive tape. Therefore, tear off one side of adhesive tape, and fix the wedges.
  • 11. White balance adjustment (Black & White tracking) can now be performed.
WHITE BALANCE ADJUSTMENT (Black and White Tracking)

  • 1. Display a monochrome pattern.
  • 2. Set the RED and GREEN DRIVE VRs for their mechanical centre.
  • 3. Turn the RED, GREEN and BLUE CUT-OFF VRs and the SCREEN VR fully counterclockwise.
  • 4. Display a horizontal line. (Select the CUT-OFF SERVICE SWITCH fron N to S and a HORIZONTAL LINE will appear.)
  • 5. Turn SCREEN VR slowly clockwise until a very faint horizontal line appears.
  • 6. Turn the CUT-OFF VR of the colour which has appeared first, clockwise by about 10° and then adjust the SCREEN VR again so that the colour may shine faintly.
  • 7. Turn the other colour CUT-OFF VRs slowly clockwise until a reasonable white line appears.
  • 8. Return the monochrome pattern. (When returning a monochrome pattern select the CUT-OFF SERVICE SWITCH- from S to N and a monochrome pattern will appear.)
  • Adjust the RED and GREEN DRIVE VRs for best white highlights.

- NOTICE

O Voltage values and waveforms are measured by respect tively receiving and displaying on the screen the colour hars signals of the PAI

[Voltage value display method]

The voltage values indicated on the circuit diagrame and voltage lists are obtained when PAL colour bar signals are received and displayed on the screen

Multimeter used DC 20kΩ/V

Given figures are all DC voltages

Sween speed of oscilloscope

uep speed of or us/div V → 5 mS/div

Others -> sweep speed specified

• Since the circuit diagram is a standard one the circuit and circuit constants may be subject to change for improvement without any notice.

SAEETV

FR (AAAFR) denotes a fusible resistor which operates as a fuse When replacing fusible resistors and parts indi cated with black shading ( ) in the circuit diagrams. be sure to ensue safety by using designated parts.

As to other parts too, use designated parts to maintain safety and performance

NOTE FOR SERVICE ---

This model's power circuit is partly different in the GND The difference of the GND is shown by the LIVE primary: ____) side GND and the NEUTRAL (secondary: _____) side GND

Don't short between the LIVE side GND and NEU-TRAL side GND or never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and NEUTRAL side GND at the same time

If above note will not be kept, a fuse or any parts will be broken
