Safety Instructions, Warnings, and Notes
2.1
Safety Instructions
h
It is not allowed to operate the FTV-set without glass plate. One function of this glass plate is to absorb Infrared Radiation.
Without this glass plate the level of Infrared Radiation produced by the plasma display could damage your eyes.
1.
Safety regulations require that during a repair:
– the set should be connected to the mains via an isolating transformer (in this particular case a transformer of
≥ 800 VA).
– safety components, indicated by the symbol h, should be replaced by components identical to the original ones.
2.
Safety regulations require that after a repair the set must be returned in its original condition. In particular attention should be paid to the following points.
– Note: The wire trees should be routed correctly and fixed with the mounted cable clamps.
– The insulation of the mains lead should be checked for external damage.
– The electrical DC resistance between the mains plug and the secondary side should be checked (only for sets that have a mains isolated power supply). This check can be done as follows:
• unplug the mains cord and connect a wire between the two pins of the mains plug;
• set the mains switch to the on position (keep the mains cord unplugged!);
• measure the resistance value between the pins of the mains plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 M
Ω and 12 MΩ;
• switch off the TV and remove the wire between the two pins of the mains plug.
– The cabinet should be checked for defects to avoid touching of any inner parts by the customer.
2.2
Warnings
ESD w
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD w). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential.
1.
Available ESD protection equipment:
– complete kit ESD3 (combining all 6 prior products - small table mat) 4822 310 10671
– wristband tester 4822 344 13999
2.
Never replace modules or other components while the unit is switched on.
3.
When making settings, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a circuit becoming unstable.
2.3
Notes
1.
A glass plate is positioned before the plasma display. This glass plate can be cleaned with a slightly humid cloth. If due to circumstances there is some dirt between the glass plate and the plasma display panel it is recommended to do some maintenance by a qualified service employee only.
2.
Never disconnect the power display cable when the set is operating
3.
With DST no failures (error-codes) can be red, when the set is in Service-mode.
4.
If DST reacts with "error 2", there is no communication between the TV and the DST. Note that the IR-transmitter
FHP PDP 2.
EN 5
LED is positioned at the right side of IR-receiver eye of the
E-box. Take into account that receiver-LED on DST is positioned not in the middle but at the left side. Point corresponding LEDs to each other. In case the amount of
Infrared produced by the screen pollutes the communication, the set can be set in Stand-by-mode. Then still the error-messages can be retrieved.
2.3.1
Notes on Safe Handling of the Plasma Display
Notes to Follow During Service
• The work procedures shown with the Note indication are important for ensuring the safety of the product and the servicing work. Be sure to follow these instructions.
• Before starting the work, secure a sufficient working space.
• At all times other than when adjusting and checking the product, be sure to turn OFF the main POWER switch and disconnect the power cable from the power supply of the display during servicing.
• To prevent electric shock and breakage of PC board, start the servicing work at least 30 seconds after the main power has been turned off. Especially when installing and removing the power supply PC board and the SUS PC board in which high voltages are applied, start servicing at least 2 minutes after the main power has been turned off.
• While the main power is on, do not touch any parts or circuits other than the ones specified. The high voltage power supply block within the PDP module has a floating ground. If any connection other than the one specified is made between the measuring equipment and the high voltage power supply block, it can result in electric shock or activation of the leakage-detection circuit breaker.
• When installing the PDP module in, and removing it from the packing carton, be sure to have at least two persons perform the work white being careful to ensure that the flexible printed-circuit cable of the PDP module does not get caught by the packing carton.
• When the surface of the panel comes into contact with the cushioning materials, be sure to confirm that there is no foreign matter on top of the cushioning materials before the surface of the panel comes into contact with the cushioning materials. Failure to observe this precaution may result in, the surface of the panel being scratched by foreign matter.
• When handling the circuit PC board, be sure to remove static electricity from your body before handling the circuit
PC board.
• Be sure to handle the circuit PC board by holding the large parts as the heat sink or transformer. Failure to observe this precaution may result in the occurrence of an abnormality in the soldered areas.
• Do not stack the circuit PC boards. Failure to observe this precaution may result in problems resulting from scratches on the parts, the deformation of parts, and short-circuits due to residual electric charge.
• Routing of the wires and fixing them in position must be done in accordance with the original routing and fixing configuration when servicing is completed. All the wires are routed far away from the areas that become hot (such as the heat sink). These wires are fixed in position with the wire clamps so that the wires do not move, thereby ensuring that they are not damaged and their materials do not deteriorate over long periods of time. Therefore, route the cables and fix the cables to the original position and states using the wire clamps.
• Perform a safety check when servicing is completed. Verify that the peripherals of the serviced points have not undergone any deterioration during servicing. Also verify that the screws, parts and cables removed for servicing purposes have all been returned to their proper locations in accordance with the original setup

General
Before dismounting panels read notes below!
Caution when removing circuit board!
When removing the circuit board after the main power is turned on/off, wait for at least one minute before starting to remove the circuit board.
If the circuit board removal is started immediately after turning off the main power, it can result in electric shock or damage to the circuit due to residual electric charge.
Caution on handling the FPC connector!
To release the black lock lever of the connector, flip it up gently in the middle with the nail of the thumb or forefinger, from the side with the cable.
Never pinch the lock lever with fingers or tools. Doing so might damage the lock lever.
