Entering Hyundai LCD factory menu
Push MUTE => MENU => OK => SLEEP button in interval of 1 second
Adjustment and calibration equipment
Digital multi-meter, signal generator (with SCART/RGB signal output), oscillograph, PC set ( preset the program of flash written), K7253(VGA signal generator), CA210 (LCD white balancer) DVD displayer, TV with SCART connector 1 set, IF signal generator
Writing the memory unit N4, N20, N303, N302
Main board adjustment and calibration
a) Main board X501 Connect infra-red receiving board (as per connect diagram), insert the output plug of power supply adapter( FSP060-1AD103 for 17,20’) into X1, when the indication lamp of infra-red receiving board should be in red
b) Connect PC set. Run FLASH N20 upgrade program, push POWER key on the remote control set, when the indication lamp of infra-red receiving board should be in red
c) About 4 minutes later, indication lamp of infra-red receiving board turns to yellow/blue (HLT-1751/HLT-2051), measure L102 PIN2 5.0 V,L107 PIN2 3.3 V, N10 PIN2 1.8 V, and N12 PIN2 1.8 V.
d) Write DDC program
TV board adjustment - IF adjustment
a) Input DV 5V into TP2, input 12V to TP6, Input 5V to TP4 and input 0V to TP5, monitor voltage of TP3, input 38.9 MHz signal to TP1, and use a non-inductance screw driver to adjust IFT L207 so that TP3 voltage is 1.65V
b) Input DC 5V into TP2, input 12V to TP6, Input 0V to TP4 and input 5V to TP5, monitor voltage of TP3, input 33.9 MHz signal to TP1, adjust potential meter RP202 to set TP3 voltage to 1.65V.
c) Connect IF line of tuner, control line L and L’: three disconnected points in total.
Connect main board, TV board, infra-red receiving board (as per connect diagram), push POWER key on the remoter control set, when the indication lamp of infra-red receiving board is in yellow/blue (HLT-1751/HLT-2051),measure PIN2 of N301to be 3.3 V on TV board, one end of SMT conductance L632 to be 5V, another end of SMT conductance L632 to be 12V.
AGC Adjustment
Receive D-8 signal of 60 db, measure the voltage of positive pole of D201 with DC potential meter.
Adjust potential meter RP201 to make reading of potential meter just decrease below 4.0V.Input 100db from antenna, the picture should not appear non-synchronized and distorted, input weak signal of 35 dB--40 dB, color should not disappear, picture synchronizes, normal sound.
White balance adjustment ( Use LCD special white balancer CA210,K7253 signal generator)
a) Assembly complete set;
b) Enter factory menu, realize “PW1306 reset”, adjust background brightness to be maximum;
c) Quit factory menu, enter D_SUB channel, input 60 HZ “pane signal”(C_Hat_16x12(W)),to VGA terminal. Thus the discrimination rate should be the best discrimination rate for the LCD screen, see table 1, enter user menu, adjust brightness to 50, contrast to 50 adjust line center, field and center to make the picture location to be correct.
d) Input “16 grades of grey degree” signal (Gray(H)-16), enter factory menu, realize AQC calibration”
e) Quit factory menu, input “8 grey degree” signal ( Gray(H)-8 ), enter user menu, adjust brightness and contrast, measure sixth degree with CA-210, make Y to 180 cd/m2 , enter factory menu, ,fix green to be 50,adjust red, blue to make x=284,y=299.(This procedure may not be taken now)
f) Enter AV mode, input “8 grey degree” signal, adjust tint to 0, adjust brightness and contrast, measure sixth degree with CA-210, make Y to 180 cd/m2 , enter factory menu, ,fix green to be 50,adjust red, blue to make x=284,y=299.
