(2) 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:

Signal definition and function Display data signal R7/G7/B7 is the highest intensity bit. R0/G0/B0 is the lowest intensity bit. Display data timing signal: Data are read when DCLK is low. DCLK is continuously input. Regulates one horizontal line of data: Begins control of the next screen when Hsync is lowered. Screen starts up control timing signal: Begins control of the next screen when Vsync is lowered. Input the same frequency in both odd-numbered and even-numbered fields. This signal specifies the display field. H: Odd-numbered field L: Even-numbered field Parity signal should be alternated in every Vsync cycle. This signal is arbitrarily reversed internally when there is no reversing signal. 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. Set the number of blanking signals in 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.

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.

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. The PWMAX setting is switched to constant brightness (peak electric power) control. The password setting is necessary to turn on this setting.

4.3 Checking the Product Requested for Repair
Check the serial ID number of the product requested for repair before starting the problem analysis and repair. Structure of serial ID number is shown below. (1) Checking serial ID number of PDP module (14 digits) The serial ID number of the product that is brought in for service and that of the completed panel chassis has the structure as shown below. The serial ID number is shown on the bar code label that is attached to the rear of the chassis (aluminum). N5A 1 01 001A1 01A Version No.: 01 ~ 99 A ~ Z (excluding I and O) Lot No.: 001 ~ 999 A ~ Z (excluding I and O) 1~3 Production week code: 01 ~ 53 Production year (low digit): 0 ~ 9 Product code: N5A ,P5A and S5A model 32 H1 type Module product label Serial ID label of panel chassis
The module serial ID number and the serial ID number of the completed chassis (product requested for repair) are usually the same when the product is brought in for repair for the first time. (2) Checking serial ID number of constituent PC boards (12 digits) The serial ID number of the module constituent PC boards has the following structure. The serial ID number is shown on the bar code label that is attached to each PC board. GG 1 01 0001 01A Version No.: 01 ~ 99 A ~ Z (excluding I and O) Lot No.: 0001 ~ Z9999 Production week code: 01 ~ 54 Production year (low digit): 0 ~ 9,A~ K(10-20) Product code: GG X-SUS board : GJ Y-SUS board : GE ABUSR board : GD ABUSL board : GF LOGIC board : -- PSU board

4.4 Operation Test Procedure
(1) Prepare the test equipment and the module requested for repair.
(2) Affix to the stand (jig) the module requested for repair.
(3) Connect LOGIC board connector CN1 of the module to the Interface board (jig) CN5 with the dedicated signal cable. (4) Connect the AC power cable to the module requested for repair.
(5) Turn on the AC power to the interface board (jig).
(6) Select the signal used when a problem occurs, or an all white pattern.
(7) Set the PDP go switch on the Interface board (jig) to ON. (The main power of the module is turned on.)

Panel Chassis Replacement Procedure
(1) Remove the 6 types of printed-circuit board (X-SUS, Y-SUS, ABUSL, ABUSR, LOGIC, and 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 four FPC cables (WHT) that are used to connect the circuit boards.
(2)
Remove the rivets fixing the complete panel chassis (maintenance part) and XBB board in position (4 locations). * The removed rivets are used only for keeping the machine from shifting during transportation, and are not used for the product.
