DESCRIPTION OF BLOCK DIAGRAM
1. Video Control Circuit
1) TDA4885 (U101) receives the video signal from PC and amplifies the levels of video signal (0V~0.7V), and controls the contrast signal. 2) The biases of A/D inputs control the reference output voltages of TDA4885 (U101) to proper R, G, B bias levels through the Diodes (D101, D102, D103). 4) The EX-OR (U604) device outputs the voltage levels to decide the polarities of HSYNCIN and VSYNCIN that supply the sync signals to the PLL IC and MICOM.
5. LVDS Circuit
LVDS transmitter (U701, U702) delivers digital signal to the receiver of module by the voltage swing of 1V. The peripheral circuitry of transmitter gets the DHS, DVS, DEN, DISPCLK signal, outputs LVDS signal. At the power down mode, MICOM lets the power down signal be low and Shuton pin be active low.
6. Input Switching Circuit
This circuit consists of BA7657F (U601), slide switch and TTL gates. BA7657F (U601) switch analog R, G, B signal to be entered form 15p D-SUB A(J2) or B(J3). If the position of slide switch is A; R, G, B signal and H/V Sync are entered from D-SUB A. If the Position of slide switch is B; R, G, B signal and H/V sync are entered from D-SUB B. If the position of slide switch is Auto; R, G, B signal and H/V sync are automatically selected A or B by control signal of MICOM. But if A and B are incidentally connected, system display OSD, Ò2 Input active... select A or BÓ. TTL gates (U602, U603, U604) switch H/V sync to be entered from D-SUB A or B.
2. A/D Converter Circuit
1) AD9483 (U201) converts from the analog video signal to the digital signal. For this function, its DC 2.5V output is connected to VREF_IN and it samples the input signal between 2.0V~3.0V. (The reference voltage of the sampling is 2.5V.) 2) The frequency range of 8-bit digital output is from 12.5MHz to 67.5MHz with respect to modes. 3) The status of power down pin is low for normal state and high for power down state.
7. DC/DC Converter
This curcuit supplies stand-by 5V (5VST) that is made using IC U801 regulator for MICOM and SYNC processing. The 5VDD voltage is converted using MAX785 (U802) and supply to IC need to it. The 8VA is converted using 8V regulator (U808) and supply to video pre-amp. The 3.3V voltage is converted using 6 Diodes and supply to IC need to it. The 5VA is converted using 5V regulator (U809) and supply to A/D converter and PLL IC. The state of power down make all voltage except 5VST down using SHDN.
3. Features of ICS1522 PLL IC
1) ICS1522 (U11) generates the pixel clock for each mode with respect to internal register setting, which is used to sampling circuitry. The range of the pixel clock is approximately from 25MHz to 135MHz
4. Video Process Circuit
This circuit consists of MXIC (U501) and frame memorys (U401, 402, 403) which convert frame date of input signal to 60Hz frame date. This function is processed by MX88272. The MX88272 (U501) gets the video signal converted analog to digital, interpolates input to 1280x1024 resolution signal and outputs 8-bit R, G, B, DHS, DVS and DE signals to the transmitter (U701, U702).
8. System Controller (08XL36) Circuit
This curcuit consists of EEPROM IC (U902) which stores control data, RESET IC (U904) and LED driver Q01 and Q02 indicate that power is ON or OFF. The operating procedures of MICOM and its associated circuit are as follows:
- 13 -
1) The MICOM distinguishes polarity and frequency of the horizontal sync and the vertical sync are supplied from signal cable. The controlled data of each mode is stored in EEPROM. 2) User can adjust screen condition by each OSD function. (H-Position, V-Position, Clock, Clock Phase, ... etc.)
10. OSD Control Circuit
When the MX88272 outputs the area which is able to display overlay using OSDBLNK PIN of MX88272. OSD (On-Screen-Display) device (U502) outputs display data as the timing of the signal.
11. Power Module Circuit
This block supplies the +12V to the inverter for the backlight voltage of module and the +5V for data control of LCD module. That is, SI4925DY (Q01) is switched by TR Q12 for module voltage.
9. DDC Circuit
This circuit consists of MICOM (U901) and bidirection switching IC (U2). 1) Bidirection switching IC switch I 2 C line for DDC communication by control signal of MICOM (U901). 2) The MICOM has D-SCL, D-SDA line for sending and receiving data to adjust line through 15-pin D-sub connector. 3) The data of EDID DDC information is stored in EEPROM IC (U902).

ADJUSTMENT
All adjustment are thoroughly checked and corrected when the monitor leaves the factory, but sometimes several minor adjustment may be required. Adjustment should be following procedure and after warming up for a minimum of 10 minutes. ¥ Alignment appliances and tools. - Compaq PC (Desktop Pro 2000) - Programmable Signal Generator. (eg. VG-819 made by Astrodesign Co.) - E(E)PROM with each mode data saved. - Alignment Adapter and Software. 1. Adjustment for Factory Preset Mode 1) Select EEPROM all clear command and Enter. 2) Display cross hatch pattern at Mode 1. 3) Run alignment program for LQ800 on the IBM compatible PC. 4) Select COMMAND PRESET START command. 5) Select FOS ADJ command and Enter. 6) No attempt to manually adjust, but select each menu (H-position, V-position, Clock, and Clock Phase) with Up, Down keys (+, -) on the keyboard, then automatically adjusted and saved to the EEPROM. (DonÕt adjust H-Position, V-Position, Clock and Clock Phase.) 7) Display from Mode 2 to Mode 16 and repeat above adjustment. 8) Select PRESET EXIT command and Enter. 2. Adjustment for White Balance 1) Display color 0,0 pattern at Mode 16. 2) Set External Bright to max position and Contrast to 52 Position. 3) Select PRESET START BIAS CAL command and Enter. 4) No attempt to manually adjust, BIAS data is automatically adjusted and saved to the EEPROM. 5) Display color 15,0 pattern at Mode 16. 6) Select DRIVE CAL command and Enter. 7) Color 1 (9300K) and Color 2 (6500K) are automatically adjusted and saved to the EEPROM. 8) Select PRESET EXIT command and Enter.
