SAFETY PRECAUTIONS

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by inthe Schematic Diagram and Replacement Parts List. 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 lsolation Transformer should always be used duringthe servicing of a receiver whose chassis is not isolated fromthe AC power line. Use a transformer of adequate power ratingas this protects the technician from accidents resulting inpersonal injury from electrical shocks.

It will also protect the receiver and it's components from beingdamaged by accidental shorts of the circuitary that may beinadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this monitor is blown, replaceit with the same specified type.

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.

Leakage Current Cold Check(Antenna Cold Check)With the instrument AC plug removed from AC source,connect an electrical jumper across the two AC plug prongs.Place the AC switch in the on positioin, connect one lead ofohm-meter to the AC plug prongs tied together and touch otherohm-meter lead in turn to each exposed metallic parts such asantenna terminals, 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 ACvoltmeter with 1000 ohms/volt or more sensitivity.Reverse plug the AC cord into the AC outlet and repeat ACvoltage measurements for each esposed 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 sepcified, there ispossibility of shock hazard and the set must be checked andrepaired before it is returned to the customer.

ADJUSTMENT INSTRUCTIONS

1. Application ObjectThese instructions are applied to all of the PDP TV, AF-044A.

2. Notes(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) Adjustments must be done in the correct order.(3) The adjustments must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity ifthere is no specific designation.

(4) The input voltage of the receiver be must kept 100~240V,50/60Hz when adjusting.

(5) The receiver must be operational for about 15 minutesprior to the adjustments.

1) After receiving 100% white pattern, the receiver must beoperated prior to adjustment. (Or 7. White Patterncondition in EZ - Adjust)

2) Enter into White Pattern - Enter the Ez - Adjust by pressing ADJ Key on Service

Remote Control (S R/C).- Select the 7. White Pattern using CH +/- Key and

press the Enter(Y) Key. Display the 100% Full White Pattern.

[ Set is activated HEAT-RUN without signal generator inthis mode.

If you turn on a still screen more than 20 minutes (EspeciallyDigital pattern(13 CH), Cross Hatch Pattern), an afterimagemay occur in the black level part of the screen.
