INTRODUCTION

This service manual provides service instructions for the PTV Models listed below. Service personnel should read this manual thoroughly before servicing these chassis.

V22 Chassis V22+ Chassis

WS-48313 WS-48413 WS-55313 WS-55413 WS-65313 WS-65413

This service manual includes:

1. Assembly and disassembly instructions for the front and rear cabinet components.

2. Servicing of the Lenticular Screen and Fresnel Lens.

3. Servicing printed circuit boards (PCBs).

4. CRT replacement procedure.

5. Electrical adjustments.

6. Chip parts replacement procedures.

7. Circuit path diagrams.

The parts list section of this service manual includes:

1. Cabinet and screen parts.

2. Electrical parts.

Schematic and block diagrams of the above listed models are included in this service manual for better understanding of the circuitry. PCB drawings are also included for easy location of parts and test points.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in television receivers 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 special safety characteristics are identified in this service manual.

Electrical components having such features are identified by shading on the schematic diagram and by bold

type in the parts list of this service manual. The replacement for any safety part should be identical in value and characteristics.

Page 5

MODELS: WS-48313 / WS-48413 / WS-55313 / WS-55413 / WS-65313 / WS-65413

SAFETY PRECAUTIONS

NOTICE: Observe all cautions and safety related notes located inside the receiver cabinet and on the

receiver chassis.

WARNING:

1. Operation of this receiver outside the cabinet or with the cover removed presents a shock hazard from the receiver's power supplies. Work on the receiver should not be attempted by anyone who is not thoroughly familiar with the precautions necessary when working on high voltage equipment.

2. Do not install, remove or handle the picture tubes in any manner unless shatterproof goggles are worn. People not so equipped should be kept away while the picture tube is being handled. Keep the picture tube away from the body while handling.

3. When service is required, observe the original lead dress. Extra precaution should be taken to assure correct lead dress in the high voltage area. Where a short-circuit has occurred, replace those components that indicate evidence of overheating.

X-Radiation warning

The surface of the cathode ray tubes (CRTs) may generate X-Radiation, so take proper precautions when servicing. It is recommended that a lead apron be used for shielding while handling the CRT. Use this method if possible.

When replacing the CRTs, use only the designated replacement part since it is a critical component with regard to X-Radiation. High voltage must be set as prescribed under the section titled Electrical Adjustments.

Leakage current check

Before returning the receiver to the customer, it is recommended that leakage current be measured according to the following methods.

1. Cold Check

With the alternating current (AC) plug removed from the AC source, place a jumper across the two AC plug

prongs. Connect one lead of an ohm meter to the AC plug and touch the other lead to each exposed metal part (i.e. antennas, handle bracket, metal cabinet, screw heads, metal overlay, control shafts, etc.), particularly any exposed metal part that has a return path to the chassis. The resistance of the exposed metal parts having a return path to the chassis should be a minimum of 1Mega Ohm. Any resistance below this value indicates an abnormal condition and requires corrective action.

2. Hot Check ...Use the circuit shown below to perform the hot check test.

1. Keep switch S1 open and connect the receiver to the measuring circuit. Immediately after

connection, and with the switching devices of the receiver in their operating positions, measure the leakage current for both positions of switch S2.

2. Close switch S1, energizing the receiver. Immediately after closing switch S1, and with the

switching devices of the receiver in their operating positions, measure the leakage current for both positions of switch S2. Repeat the current measurements of items 1 and 2 after the receiver has reached thermal stabilization. The leakage current must not exceed 0.5 milliampere (mA).

ANODE LEAD REMOVAL

CAUTION: To prevent damage, the following procedure must be used when removing an

Anode Lead from the Flyback Transformer.

1) Push the Anode Lead down.

3) Carefully remove the Anode Lead

1. Removal of the CRT

Caution! High voltage should be completely discharged prior to CRT removal.

Since the CRTs receive high voltage from the Flyback transformer, discharge by shorting the open end of the respective high voltage cable to chassis ground.

from the Flyback Transformer.

CRT REPLACEMENT

2) While holding the lead down rotate the lead 90º counter clockwise.

Note: Refer to Cabinet Disassembly when performing steps 1 through 2.

1. Remove the Speaker Grille, Front Board, and Screen Assy.

2. Remove the Back Board.
