SAFETY PRECAUTIONS

NOTICE: Comply with all cautions and safety related notes located on or inside the cabinet and on the chassis.

The following precautions should be observed:

1. When service is required, even though the PDP UNIT an isolation transformer should be inserted between the power line and the set in safety before any service is performed.

2. When replacing a chassis in the set, all the protective devices must be put back in place, such as barriers, nonmetallic knobs, adjustment and compartment cover shields, isolation resistor capacitor, etc.

3. When service is required, observe the original lead dress. Extra precaution should be taken to assure correct lead dress in the high voltage circuitry area.

4. Always use the manufacturer's replacement components. Especially critical components as indicated on the circuit diagram should not be replaced by other manufacturers. Furthermore where a short circuit has occurred, replace those components that indicate evidence of overheating.

5. Before returning a serviced set to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock. Also be sure that no protective device built into the set by the manufacture has become defective, or inadvertently defeated during servicing. Therefore, the following checks should be performed for the continued protection of the customer and service technician.

6. Perform the following precautions against unwanted radiation and rise in internal temperature.

• Always return the internal wiring to the original styling.

• Attach parts (Gasket, Ferrite Core, Ground, Rear Cover, Shield Case etc.) surely after disassembly.

7. Perform the following precautions for the PDP panel.

• When the front case is removed, make sure nothing hits the panel face, panel corner, and panel edge (so that the glass does not break).

• Make sure that the panel vent does not break. (Check that the cover is attached.)

• Handle the FPC connected to the panel carefully. Twisting or pulling the FPC when connecting it to the connector will cause it to peel off from the panel.

8. Pay attention to the following.

• When the front case is removed, infrared ray is radiated and may disturb reception of the remote control unit.

• Pay extreme caution when the front case and rear panel are removed because this may cause a high risk of disturbance to TVs and radios in the surrounding.

Leakage Current Cold Check

With the AC plug removed from an AC power source, place a jumper across the two plug prongs. Turn the AC power switch on. Using an insulation tester (DC 500V), connect one lead to the shortcut AC plugs and touch the other lead to each exposed metal part (input/output terminals, screw heads, metal overlays, control shafts, etc.), particularly any exposed metal part having a return path to the chassis. Exposed metal parts having a return path to the chassis should have a minimum resistor reading of 0.3MΩ and a maximum resistor reading of 5MΩ . Any resistor value below or above this range indicates an abnormality that requires corrective action. Exposed metal parts not having a return path to the chassis will indicate an open circuit.

Leakage Current Hot Check

Plug the AC line cord directly into an AC power source (do not use an isolation transformer for this check). Turn the AC power switch on. Using a "Leakage Current Tester", measure for current from all exposed metal parts of the cabinet (input/output terminals, screw heads, metal overlays, control shaft, etc.). Do this particularly for any exposed metal part having a return path to the chassis, to a known earth ground (water pipe, conduit, etc.). Any current measured must not exceed 0.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE SET TO THE CUSTOMER.

Charged Section

The places where the commercial AC power is used without passing through the power supply transformer. If the places are touched, there is a risk of electric shock. In addition, the measuring equipment can be damaged if it is connected to the GND of the charged section and the GND of the non-charged section while connecting the set directly to the commercial AC power supply. Therefore, be sure to connect the set via an insulated transformer and supply the current.

Detection in protection mode

The structure of three detections was prepared.

a. Opening of a Rear case is detected by mechanical switch. b. Simple logic via a connector. c. It is necessary to control IC by I2C from MAIN microcomputer.

Detection of B and C is for not operating SLOT independently.

Protection mode

When operation of abnormalities is detected, the MAIN microcomputer memorizes a history to E2PROM (MAIN). And it will change to protection mode. Light Emitting Diode blinks as follows at the time of protection mode.

Even if you are going to supply AC again, it goes into protection mode again by the history memorized by E2PROM.

Release in protection mode

A procedure is shown below.

1. Pushing INPUT of BODY-KEY is continued 5 seconds or more.

2. Light Emitting Diode changes to lighting of the red that shows a standby state from blink in protection mode.

3. You have to push the following keys in order within 5 seconds from red lighting.

VOL - -> INPUT -> VOL+ -> POWER ON

CAUTION: PDP will return to protection mode again, when release is impossible within 5 seconds and a mistake is made in pushing body-key.

ADJUSTMENTS

Adjusting Mode

SERVICE MODE

In this mode, picture-quality adjustments more accurate than those made on the normal user menu and various functions for alleviating phosphor burn can be performed.

In order to use this mode, you should make PDP the stand-alone. (Or it recommends removing a communication cable with FEB.) And PDP is made standby (OFF). (Light Emitting Diode must be red lighting.)

The following operations are made into turn in order to go into this menu:

1. It pushes “VOLUME UP” of BODY key first.

2. Next, it pushes “VOLUME DOWN” of Body key.

3. Finally it pushes “POWER ON” of BODY key.

It is necessary to perform these operations quickly. All operations need to carry out within 3 seconds. If it puts into service mode, a display will come out to the upper left, “SERVICE MODE”(SERVICE MENU).

Operation of a service menu can be performed by the remote control that outputs the Thomson code. And the body key can operate it also.

To select category (Picture, Screen and etc.), press LEFT or RIGHT key. Moving a cursor with UP or DOWN key will highlight items (CONTRAST, BRIGHTNESS and etc.). To chose an item, press OK key. When operating it by the body key, it is the same as menu operation in PC mode at the time of FEB connection.

To escape from a service menu display, press EXIT or MENU key.

Notes: A service menu does not escape from the mode, even if a signal is lost. (Action differs from the menu for users.) In this case, only OPTION can be operated. Again, when a signal is inputted, it is the PICTURE MENU.

List of RS-232C commands

When a command is received, there is action, such as being displayed. These commands have some which operate by input video signal limitation. *Mask color becomes effective at POWEROFF/ON.

- RS-232C adjustment validity: Shows availability in RS-232C adjustment (service) mode. The AJY command is needed when using these commands.

- Normal validity: Shows availability in normal operating mode. Valid commands can be used even if they do not follow the sending of the AJY command.

- Factory adjustment validity: Shows availability in Factory adjustment mode. As for this mode, it will be used only at the time of exchange of a circuit board, and a fatal condition. The FAY command is needed when using these commands. Especially factory adjustment mode should use it carefully. If usage is mistaken, trouble will appear in a product

- Numerical direct validity: Shows commands that, if transmitted followed by 3-digit numbers, can directly set the adjustment value.

- Up/Down validity: Shows whether or not a command, if transmitted followed by Upn/DWn (with n a number from 0 to 9), can or cannot increase the adjusted value by that number alone.
