1.3.3 I/O Interface Specification

(1) LVDS Signal Definition and Function

A video signal (display data signal and control signal) is converted from parallel data to serial data with the LVDS transmitter and further converted into four sets of differential signals before input to this product. These signals are transmitted seven times faster than dot clock signals. The dot clock signal is converted into one set of differential signals by the transmitter before input to this product. The LVDS signal definition and function are summarized below:

2 SAFETY HANDLING of THE PLASMA DISPLAY

2.1 NOTES TO FOLLOW DURING SERVICING

 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 source of the display (jig or the display itself) 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 4 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 while 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 such 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.

least four minutes 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.

Remove the circuit board following the steps below. To install the circuit board, reverse the removal procedure.

(1) Remove the fixing screws (M3x8) fixing XBB at 4 locations.

(2) Pull out the XBB board horizontally and disconnect the connectors (CN26, CN27).

(3) Release the lock of the FPC connector (CN20) and disconnect the signal cable.

(4) Disconnect the cables from the VH connectors (CN22, CN23, CN24).

(5) Remove the fixing screws (M3x8) fixing XSUS at 7 locations.

(6) Release the space holder (rod) at the 3 locations.
