DESCRIPTION OF BLOCK DIAGRAM
1. Video Controller Part.
This part amplifies the level of video signal for the digital conversion and converts from the analog video signal to the
digital video signal using a pixel clock.
The pixel clock for each mode is generated by the PLL.
The range of the pixel clock is from 25MHz to 149MHz.
This part consists of the Scalar, ADC converter, TMDS receiver and LVDS transmitter.
The Scalar gets the video signal converted analog to digital, interpolates input to 1920 x 1080 resolution signal and
outputs 8-bit R, G, B signal to transmitter.
2. Power Part.
This part consists of the one 3.3V, and one 1.8V regulators to convert power which is provided 5V in Power board.
14.5V is provided for converter board, 5V is provided for Main board.
Also, 5V is converted 3.3V and 1.8V by regulator. Converted power is provided for IC in the main board.
The inverter operates back-light lamps of module.
3. MICOM Part.
This part is including video controller part. And this part consists of Reset IC and the Micom.
The Micom distinguishes polarity and frequencies of the H/V sync are supplied from signal cable.
The controlled data of each mode is stored in scalar.

Power Board Block Diagram
1. EMI components.
This part contains of EMI components to comply with global marketing EMI standards like FCC, VCCI CISPR, the
circuit included a line-filter, across line capacitor and of course the primary protection fuse.
2. Input rectifier and filter.
This part function is for transfer the input AC voltage to a DC voltage through a bridge rectifier and a bulk capacitor.
3. Energy Transfer.
This part function is for transfer the primary energy to secondary through a power transformer.
4. Output rectifier and filter.
This part function is to make a pulse width modulation control and to provide the driver signal to power switch, to
adjust the duty cycle during different AC input and output loading condition to achieve the dc output stabilized, and
also the over power protection is also monitor by this part.
5. Photo-Coupler isolation.
This part function is to feed back the DC output changing status through a photo transistor to primary controller to
achieve the stabilized DC output voltage.
6. Signal collection.
This part function is to collect the any change from the DC output and feed back to the primary through photo
transistor.
7. Boost circuit: Boost converter, the function is to convert 14.5V to the turn-on voltage of LED.
8. On/Off circuit: Main board provides ENA signal to make the converter system On or Off.
9. DIM circuit: Main board provides PWM signal to make the light LED On or Off.
10. IC MP3389EF: Converter controls IC, the function: provide PWM driver signal to Boost converter, balance the
LED current, set the maximum output voltage of OVP.
11. OVP circuit: set the maximum output voltage of OVP, through this voltage IC can neglect the OPENs string.
12. Current feedback: LED feedback current detection.

Operating System: DOS, windows98, 2000, XP
1. Parallel port setting
Enter your bios, and do as followings.
a) Integrated peripheral
b) Super IO Device
c) Parallel port mode
you should set the parallel port mode to SPP for using the DOS EDID tool surely.
2. EDID Write
1Connect the signal line of monitor with DDC recorder.
2Choose the DDC RECORD program, and it shows on the screen, the choose the correct source base on the
monitor.
3Click LoadFile ,then key in themanufacturer name, model name, product code, then choose the correct
model name base on the monitor.(as Fig.2)
4Scan serial No. to DDC recorder by Bar Reader, then read again in the Verify SN.
5According to the message of DDC program, when the picture as fig.1 appears, it show DDC record has finished.

Please check Manufacturer Name, Vendor Assigned Code, Monitor Name, Serial Number
*****[????????******] (it must be the same as Bar Code), Week of Manufacture**,Year of Manufacture****,
Checksum** (It must be the same as the last byte of data table, as follows picture shows). Above of all must be
right, then if it shows the green PASS, it means record succeeds ,the red Fail means record fails; Then check
the power supply and signal line, and ensure they are connected well ,then do DDC record again from the third
step.
