Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe Schematic Diagram and Exploded View. It is essential that these special safety parts should be replaced with the same components as recommended in this manual toprevent X-RADIATION, Shock, Fire, or other Hazards. Do not modify the original design without permission of manufacturer.
General Guidance
An isolation Transformer should always be used during theservicing of a receiver whose chassis is not isolated from the ACpower line. Use a transformer of adequate power rating as thisprotects the technician from accidents resulting in personal injuryfrom electrical shocks.
It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitry that may beinadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this monitor is blown, replace itwith the specified.
When replacing a high wattage resistor (Oxide Metal FilmResistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,extreme care should be used in handling the Picture Tube.Do not lift the Picture tube by it's Neck.
Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source, connectan electrical jumper across the two AC plug prongs. Place theAC switch in the on position, connect one lead of ohm-meter tothe AC plug prongs tied together and touch other ohm-meterlead in turn to each exposed metallic parts such as antennaterminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, themeasured resistance should be between 1MΩ and 5.2MΩ. When the exposed metal has no return path to the chassis thereading must be infinite.An other abnormality exists that must be corrected before thereceiver is returned to the customer.
Leakage Current Hot Check (See below Figure) Plug the AC cord directly into the AC outlet.Do not use a line Isolation Transformer during this check. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitorbetween a known good earth ground (Water Pipe, Conduit, etc.)and the exposed metallic parts.Measure the AC voltage across the resistor using AC voltmeterwith 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each exposed metallic part. Anyvoltage measured must not exceed 0.75 volt RMS which iscorresponds to 0.5mA.In case any measurement is out of the limits specified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.
NOTE : Specifications and others are subject to change without notice for improvement.
V Application RangeThis spec is applied to PDP TV used PP01A Chassis.
V SpecificationEach part is tested as below without special appointment.
(1) Temperature : 25 °C ± 5 °C (77 °F ± 9 °F), CST : 40 ± 5(2) Relative Humidity: 65 % ± 10%(3) Power Voltage: Standard Input voltage (100 V - 240 V ~, 50 / 60 Hz)
* Standard Voltage of each product is marked by models.(4) Specification and performance of each parts are followed each drawing and specification by part number in accordance with
SBOM.(5) The receiver must be operated for about 20 minutes prior to the adjustment.

1. Application RangeThis spec sheet is applied to all of the PP01A chassis.
2. Specification(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolationtransformer will help protect test instrument.
(2) Adjustment must be done in the correct order.(3) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relativehumidity if there is no specific designation.
(4) The input voltage of the receiver must keep 100 V~ 240 V, 50 / 60 Hz.
(5) The receiver must be operated for about 5 minutes prior tothe adjustment when module is in the circumstance of over15 °C- In case of keeping module is in the circumstance of 0 °C,
it should be placed in the circumstance of above 15 °Cfor 2 hours
- In case of keeping module is in the circumstance of below-20 °C, it should be placed in the circumstance of above15 °C for 3 hours,.
3. S/W Program Download
3-1. ProfileThis is for downloading the s/w to the flash memory of theIC402
3-4. Connection Condition(1) IC name and circuit number : Flash Memory and IC402(2) Use voltage : 3.3V (5 pin)(3) SCL : 15 pin(4) SDA : 12 pin(5) Tact time : about 2min and 30seconds
3-5. Download Method (By using MSTAR JIG)
(1) Preliminary Steps
1) Connect the download jig to D-sub jack
2) Connect the PC to USB jack
