Chassis: RF-02CA
Adjustments must be done in the correct order. The adjustment must be performed at 25±5oC of temperature and 65±10% of relative humidity.
The input voltage of the receiver must maintain 110~240V, 50/60Hz while adjusting. Operate the receiver for about 15 minutes prior to the adjustment with 100% white pattern (06CH), or white condition in HEAT-RUN mode.
Enter into HEAT-RUN mode. Press the POWER ON KEY on remote control for adjustment. OSD display HEAT-RUN WHITE and screen display 100% full WHITE PATTERN. Set is activated HEAT-RUN without signal generator in this mode. Single color pattern of HEAT-RUN mode uses to check the PANEL
(RED/BLUE/GREEN).
Caution: If you turn on a still screen more than 20 minutes, an afterinage may occur in the black level part of the screen. (Especially Digital Cross Hatch Pattern), a afterimage may be occur in the black level part of the screen.

RGB AUTO CUT-OFF & MIN BIAS
1) If the PDP Module or Power Board was replaced, adjust the Power PCB Assy Voltage prior to any other adjustment.
2) Input Full Back (0 Gray) signal which generated from Pattern Generator into Component input and RGB1 Input part.
3) Press POWER ON KEY on R/C for adjustment and select AUTO-CUT(Cut-off Auto Adjustment).
4) Press Vol. + key.
5) Screen adjustment starts with Full Black screen. Original Window screen will be presented about 5-6 seconds later. And if (OK OSD) appears on the screen, then the Auto Cut-off and Min-Bias adjustment will have been completed.
MAX BIAS ADJUSTMENT
1) Input Full White (255 Gray) signal which generated from Pattern Generator into Component input and RGB1 Input.
2) Press POWER ON KEY on R/C for adjustment and select MAX-BIAS.
3) Press Vol. + key.
4) Original Full White screen will be presented about 1-2 seconds later. And if (OK OSD) appears on the screen then the Min-Bias adjustment will have been completed.
(5) After adjustment, press ¥ key to save adjustment and come out of the adjustment mode.
To check whether the circuit adjustment is operated well or not:
1) Display RGB1 to the Main picture, Component input to the Sub picture in the TWIN PICTURE.
2) To check the MIN-Bias, input Full Black (0 gray) signal into Component input and RGB1 input part at the same time in the Pattern Generator.
3) To check the MAX-Bias, input Full White (255 gray) signal into Component input and RGB1 input part at the same time in the Pattern Generator.
4) Compare Black Level with White Level by eye. And if there is no Level difference, the adjustment is
completed.
Data value, which adjusted in the board, is valid until the VSC Board is dissued and must be protected. For the protection of data, Micom does not permit any more adjustment after completion.
In case of re-adjustment, operate First Value Setting.
Each PCB Assy must be checked by Check JIG Set before assembly. (Especially, be careful Power PCB Assy which can cause fatal Damage to PDP Module.)
POWER PCB ASSY VOLTAGE VA ADJUSTMENT
1) Test Equipment : D.M.M 1EA
2) After receiving 100% white pattern, HEAT RUN.
3) Connect + terminal of D.M.M to Va pin of P805 and connect Ð terminal to GND pin of P805.
4) After turning the VR4, voltage of D.M.M adjustment as same as Va voltage which on label of panel
Right/Top. (Deviation : ±0.5V)
VS ADJUSTMENT
1) Connect + terminal of the D.M.M to Vs pin of P805 and connect - terminal to GND pin of P805.
2) After turning the VR1, voltage of D.M.M adjustment as same as Vs voltage which on label of panel Right/Top. (Deviation : ±0.5V)
ADJUSTMENT OF WHITE BALANCE
Operate the Zero-calibration of the CA-100, then stick sensor to PDP module surface when you adjust. For manual adjustment, it is also possible by the following sequence.
1) Select WHITE PATTERN of HEAT RUN mode by pressing POWER ON KEY on remote control for adjustment then operate HEAT RUN more than 15 minute.
2) Supply 216Gray, 128Gray, 70Gray Level, 50% size length and breadth signal to RGB1 input.
3) W/B adjustment must be adjusted once and follow the sequence of Low Light Middle Light
High Light and then save the adjustment value with o Key.
4) To adjust Low Light, stick sensor to Gray Level(or 20~25 Cd/m2) Pattern, press ADJ Key on R/C for adjustment and press v, x on R/C in adjustment mode to select R-L or G-L, press VOL +, - Key and adjust it until color coordination becomes as below.
X: 0.290±0.003, Y: 0.300±0.003
Color temperature: 8, 500oK±500oK
5) To adjust Middle Light , stick sensor to Gray Level (or 70~75 Cd/m2) Pattern, press ADJ Key on remote control for adjustment and press v, x on remote control in adjustment mode to select R-M or G-M, press VOL +, -
Key and adjust it until color coordination becomes as below.
X: 0.290±0.003, Y: 0.300±0.003
Color temperature: 8, 500oK±500oK
6) To adjust High Light, stick sensor to Gray Level(or 135-140 Cd/m2) Pattern, press ADJ Key on the R/C for adjustment and press v, x on R/C in adjustment mode to select R-L or G-L, press VOL +, - Key and adjust it until color coordination becomes
as below.
X: 0.290±0.003, Y: 0.300±0.003
Color temperature: 8, 500¡K±500¡K
7) Exit adjustment mode using o Key.
