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:

This signal specifies the display field. H: Odd-numbered field Parity signal PARITY 1 Input L: Even-numbered field Parity signal should be alternated in every Vsync cycle. Display period timing signal. H indicates the display period and L indicates the non display period. Note: Set this timing properly like followings, as is used internally for signal processing. Set the blanking period so that the number of effective display data items in one horizontal period is 852. Blanking 1 Input Set the number of blanking signals in signal BLANK one vertical period to 512, which is one half the number of effective scan lines. If the BLANK changes when the Vsync frequency is switched, the screen display may be disturbed or brightness may change. The screen display is restored to the normal state later when the BLANK length is constant again. This product does not correspond to the progressive display mode by the parity signal fixation. When the parity signal is fixed, this product is reversed arbitrarily internally and used. 1 Input

Notes on safe handling of the plasma display
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 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 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.

Setting [hex] Symbol Item Function This item implements control to return the IRQ signal from "HIGH" to "Low" level when an error occurs. When this item is set to 1, the IRQ signal is returned to "Low" level. This item implements control to return the ERRF flag to 0 when an error occurs. When this item is set to 1, this setting automatically returns to 0 after returning the ERRF flag to 0. Be sure to use the display with the setting fixed to 0. This item exercise control to return the PSDF flag to 0 when this machine performs the OFF sequence at AC power shutdown. When this item is set to 1, this setting automatically returns to 0 after returning the PSDF flag to 0. When this setting is changed and the ERRC setting is read out, the error contents (as many as 16 errors) of the module that have occurred in the past can be checked. If more than 16 errors have occurred, the error code is updated starting from the oldest error. Be sure to use the display with the setting fixed to 0. Sets the maximum power consumption. Set this item in accordance with the status of the machine. Make sure that the respective parts' temperature/panel temperature stays within the specifications. If the setting is set to 3, power consumption increases to a level exceeding the standard consumption.

X-SUS Circuit Board Removal/Installation Procedure
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.
Remove the circuit board following the steps below. To install the circuit board, reverse the removal procedure. (1) (2) (3) (4) Remove the fixing screws (M3×8) at 9 locations. Release the lock of the FPC connector (CN21) and disconnect the signal cable. Disconnect the cables from the VH connectors (CN22, CN23).

Panel Chassis Replacement Procedure
(1) Remove the 6 types of printed-circuit board (X-SUS, Y-SUS, ABUSL, ABUSR, LOGIC, PSU) that are installed in the panel module. For the removal procedure, refer to Section 5.2 to 5.7. * Before removing the above 6 types of board, be sure to remove both ends of the single power cable (BLU) and those of the five FPC cables (WHT) that are used to connect the circuit boards.
63
(2) (3)
***Install the printed-circuit board that was removed in step (1) and fix it in position. Refer to the exploded view shown in Section 5.1.) Print the serial ID number of the product to be repaired on the product label which is prepared separately. Attach the product label to the panel chassis on top of the Y-SUS board (See the photo).
64
(4) When the installation of the board is complete, route the wires as shown below.
Pass the CN52 cable (RED/ BLK) under the signal cable. Route it on top of the PSU signal cable.
