Box 240007 Huntsville, Alabama 35824 Copyright Made/Printed in the U.S.A. August 2001 by LG & Zenith Electronics Corporation PRODUCT SAFETY GUIDELINES IMPORTANT SAFETY NOTICE A.C. Voltmeter This manual was prepared for use only by properly trained audio-visual service technicians. When servicing this product, under no circumstances should the original design be modified or altered without permission from Zenith Electronics Corporation. All components should be replaced only with types identical to those in the original circuit and their physical location, wiring and lead dress must conform to original layout upon completion of repairs. Special components are also used to prevent x-radiation, shock and fire hazard. These components are indicated by the letter “x” included in their component designators and are required to maintain safe performance. No deviations are allowed without prior approval by Zenith Electronics Corporation. 0.15uF Good Earth Ground such as the Water Pipe, Conduit, etc. Circuit diagrams may occasionally differ from the actual circuit used. This way, implementation of the latest safety and performance improvement changes into the set is not delayed until the new service literature is printed. 1500 OHM Place this probe on each exposed metal part. 10 WATT X-RADIATION CAUTION: Do not attempt to modify this product in any way. Never perform customized installations without manufacturer’s approval. Unauthorized modifications will not only void the warranty, but may lead to property damage or user injury. 1. Be sure procedures and instructions to all service personnel cover the subject of x-radiation. The only potential source of x-rays in current TV receivers is the picture tube. However, this tube does not emit x-rays when the HV is at the factory-specified level. The proper value is given in the applicable schematic. Operation at higher voltages may cause a failure of the picture tube or high-voltage supply and, under certain circumstances may produce radiation in excess of desirable levels. 2. Only factory-specified CRT anode connectors must be used. 3. It is essential that the service personnel have available an accurate and reliable high-voltage meter. 4. When the high-voltage circuitry is operating properly, there is no possibility of an x-radiation problem. Every time a color chassis is serviced, the brightness should be run up and down while monitoring the high voltage with a meter, to be certain that the high voltage does not exceed the specified value and that it is regulating correctly. 5. When troubleshooting and making test measurements in a product with a problem of excessively high voltage, avoid being unnecessarily close to the picture tube and the high voltage power supply. Do not operate the product longer than necessary to locate the cause of excessive voltage. 6. Refer to HV, B+, and shutdown adjustment procedures described in the appropriate schematics and diagrams (where used). Service work should be performed only after you are thoroughly familiar with these safety checks and servicing guidelines. GRAPHIC SYMBOLS The exclamation point within an equilateral triangle is intended to alert the service personnel to important safety information in the service literature. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the service personnel to the presence of noninsulated “dangerous voltage” that may be of sufficient magnitude to constitute a risk of electric shock. The pictorial representation of a fuse and its rating within an equilateral triangle is intended to convey to the service personnel the following fuse replacement caution notice: CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKED NEAR EACH FUSE. SERVICE INFORMATION IMPLOSION While servicing, use an isolation transformer for protection from AC line shock. After the original service problem has been corrected, make a check of the following: FIRE AND SHOCK HAZARD 1. Be sure that all components are positioned to avoid a possibility of adjacent component shorts. This is especially important on items transported to and from the repair shop. 1. All direct view picture tubes are equipped with an integral implosion protection system; take care to avoid damage during installation. 2. Use only the recommended factory replacement tubes. TIPS ON PROPER INSTALLATION 2. Verify that all protective devices such as insulators, barriers, covers, shields, strain reliefs, power supply cords, and other hardware have been reinstalled per the original design. Be sure that the safety purpose of the polarized line plug has not been defeated. 3. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles. 4. Check for physical evidence of damage or deterioration to parts and components, for frayed leads or damaged insulation (including the AC cord), and replace if necessary. 1. Never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf space over, or close to, a heat duct, or in the path of heated air flow. 2. Avoid conditions of high humidity such as: outdoor patio installations where dew is a factor, near steam radiators where steam leakage is a factor, etc. 3. Avoid placement where draperies may obstruct venting. The customer should also avoid the use of decorative scarves or other coverings that might obstruct ventilation. 4. Wall- and shelf-mounted installations using a commercial mounting kit must follow the factory-approved mounting instructions. A product mounted to a shelf or platform must retain its original feet (or the equivalent thickness in spacers) to provide adequate air flow across the bottom. Bolts or screws used for fasteners must not touch any parts or wiring. Perform leakage tests on customized installations. 5. Caution customers against mounting a product on a sloping shelf or in a tilted position, unless the receiver is properly secured. 6. A product on a roll-about cart should be stable in its mounting to the cart. Caution the customer on the hazards of trying to roll a cart with small casters across thresholds or deep pile carpets. 7. Caution customers against using a cart or stand that has not been listed by Underwriters Laboratories, Inc. for use with its specific model of television receiver or generically approved for use with TVs of the same or larger screen size. 8. Caution customers against using extension cords. Explain that a forest of extensions, sprouting from a single outlet, can lead to disastrous consequences to home and family. 5. No lead or component should touch a receiving tube or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided. 6. After reassembly of the set, always perform an AC leakage test on all exposed metallic parts of the cabinet (the channel selector knobs, antenna terminals, handle and screws) to be sure that set is safe to operate without danger of electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by a .15 mfd 150V AC type capacitor between a known good earth ground water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately. 2 PDP 40” - SAFETY TABLE OF CONTENTS OVERVIEW ........................................................ 5 SPECIFICATIONS ............................................. 5 CONNECTIONS/CONTROLS .................................. 6 REMOTE ........................................................ 7 TROUBLESHOOTING ............................................. 8 NO POWER ..................................................... 8 ABNORMAL PICTURE ....................................... 8 NO RASTER .................................................... 9 NO SOUND ..................................................... 9 ADJUSTMENT INSTRUCTIONS ............................... 10 PRECAUTIONS .............................................. 10 VOLTAGE ADJUSTMENTS ................................. 10 RGB CUTOFF ................................................ 10 COLOR TEMPERATURE .................................... 10 VIF VCO ...................................................... 11 AGC ........................................................... 11 OPTION TABLE.............................................. 11 PARTS ............................................................ 13 DIAGRAMS ...................................................... 14 EXPLODED VIEW ........................................... 14 INTERCONNECT ............................................. 15 PHOTO / MODULE LAYOUT .............................. 16 BLOCK DIAGRAMS ......................................... 17 VIDEO SCAN CONVERTER PCB TOP .................... 18 VIDEO SCAN CONVERTER BOTTOM ..................... 19 ADDITIONAL PCB .......................................... 20 SCHEMATICS .................................................... 21 VIDEO SCAN CONVERTER CIRCUIT ..................... 21 3 PDP 40” - TOC Overview OVERVIEW GENERAL INFO Screen Size Aspect Ratio Resolution Peak Brightness Contrast Ratio Viewing Angle Displayable Colors Weight Life Dimensions(MNT) (SPK) Input Terminals Output Terminals Input Terminals Display Frequency Picture Sound SPECIFICATIONS 40 in/101 cm diagonal 4 :3 (width:height) 640 x 480 pixels typ.330cd/m² (with 45%filter) 550:1(Dark Room with 45% filter) 160° horizontally and vertically 16.7 million 32.55kg(MNT), 6.45kg(D/Stand), 3.1kg(Spk.)x2 >25,000 hours (elapsed time to 50% of initial brightness) 930cm wide, 71.1cm high, 7.8cm deep 12cm wide, 71.1cm high, 7.8cm deep RF terminal(NTSC) Composite Video input(RCA) X 2, S-Video Audio L&R input(RCA) X 2 Component Video (Y,Cb,Cr) + R/L for DVD Component Video (Y,Pb,Pr)+ R/L for HDTV Stb.
