ADJUSTMENT INSTRUCTIONS
1. Application Object
These instructions are applied to all of the PDP monitor, NF01DC.
(3) V-y Adjustment
1) Connect pin 1 of CN802 to (+) jack of D.M.M. 2) After turning the VR751(V-y Adj), voltage of D.M.M adjust as same as Vs voltage which indicated on label of panel right/bottom.(Deviation : ±0.5V)
2. Notes
(1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. (2) Adjustment must be done in the correct order. (3) The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation. (4) The input voltage of the receiver must keep 220/230V, 50/60Hz in adjusting. (5) The receiver must be operated for about 15 minutes prior to the adjustment. 1) After receiving 100% white pattern, the receiver must be operate prior to adjustment.(Or white condition in HEATRUN mode) 2) Enter into HEAT-RUN mode - Select the HEAT-RUN OFF by pressing SVC button on Remote Control for adjustment. - Press the VOL + button in HEAT-RUN OFF. (OSD display HEAT-RUN WHITE and screen display 100% full WHITE PATTERN) 3) Set is activated HEAT-RUN without SET TOP BOX or signal generator in this mode. [ Single color pattern of HEAT-RUN mode uses to check PANEL.(RED/BLUE/GREEN)
(4) Vsetup Adjustment
1) Connect pin 5 of CN802 to (+) jack of D.M.M. 2) After turning the VR651(Vsetup Adj),voltage of D.M.M adjust as same as Vs voltage which indicated on label of panel right/bottom.(Deviation : ±0.5V)
(5) 5V Adjustment
1) Connect pin 3 of CN809 to (+) jack of D.M.M. 2) Adjust the voltage data of D.M.M to 5.1V by turning.(Deviation : ±0.5V)
(6) STBY-5V Adjustment
1) Connect pin 3 of CN808 to (+) jack of D.M.M. 2) Check the voltage(5V) of D.M.M. 3) Adjust the voltage data of D.M.M so that voltage data of D.M.M is 5V.(Deviation : ±0.5V)

(1) Va Adjusment(Address Voltage Adjusment)
1) Connect pin 1 of CN806 or CN811 to (+) jack of D.M.M. 2) After turning the VR351(Va Adj), voltage of D.M.M adjustment as same as Va voltage which on label of panel right/bottom.(Deviation : ±0.5V)

(2) Vs Adjustment
1) Connect pin 1 of CN803 to (+) jack of D.M.M. 2) After turning the VR551(Vs Adj), voltage of D.M.M adjust as same as Vs voltage which indicated on label of panel right/bottom.(Deviation : ±0.5V)

4-1. Required Equipment
Color analyzer(CA-100 or same production)
4-2. Connection Diagram of Equipment for Measuring
COLOR ANALYZER TYPE; CA-100 High Light 85±5cd/m2 Low Light 8±3cd/m2
CVBS Signal Input PDP MONITOR Window Pattern MSPG-2100 or MSTG-5200
Connection Diagram of Automatic Adjustment [ After stop the Micom by pressing IN-START Key on Remote Control, insert the P1002 with automatic adjustment of connector. After remove connector, move the Micom by pressing ENTER Key.
4-3. Adjustment of White Balance
· White Balance should be done after RGB cut-off become adjustment. · Operate the Zero-calibration of the CA--100, then stick sensor to PDP module surface when you adjust. (1) Select WHITE PATTERN of HEAT RUN mode by pressing ADJ button on Remote Control for adjustment then operate HEAT RUN more than 15 minute. (2) Supply 10 step gray scale bar signal in pattern generater. (A/V Input) (3) To adjust Low Light, stick sensor to 9th pattern(Dark), select the W/B by pressing ADJ button on Remote Control for adjustment and press the VOL + button enter Adjustment Mode. After select the G cut and B cut, press the VOL +/- Key and adjust it until color coordination becomes (R cut fixation) color coordination : X=0.280±0.005, Y=0.310±0.005 color temperature : 8.800cK ± 500cK (4) To adjust High Light, stick sensor to 2th pattern(White), select the W/B by pressing ADJ button on Remote Control for adjustment and press the VOL + button enter Adjustment Mode. After select the R GAIN and G GAIN, press the VOL +/Key and adjust it until color coordination becomes (B GAIN fixation) color coordination : X=0.280±0.005, Y=0.310±0.005 color temperature : 8.800cK ± 500cK (5) Confirm the result of the High Light adjustment. If the deviation of High Light occur, operate the adjustment of Low Light and High Light again. (6) Exit adjustment mode using Enter button.
