Proper service and repair is important to the safe, reliable operation of all AOC Company Equipment. The service
procedures recommended by AOC and described in this service manual are effective methods of performing service
operations. Some of these service operations require the use of tools specially designed for the purpose. The
special tools should be used when and as recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in
order to minimize the risk of personal injury to service personnel. The possibility exists that improper service
methods may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE
NOT EXHAUSTIVE. AOC could not possibly know, evaluate and advise the service trade of all conceivable ways in
which service might be done or of the possible hazardous consequences of each way. Consequently, AOC has not
undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not
recommended by AOC must first satisfy himself thoroughly that neither his safety nor the safe operation of the

Step4:Check whether the FW version is correct, then do “Auto Color” and “Reset”.
a. For VGA, if can’t use the recommended optimal resolution; for DVI, if no video with PC source, while picture is
normal with chroma source, it’s the reason for “DDC Loss”, so pls do DDC programming.
b. When the monitor connects the DVD or other play devices with DVI cable, and play the HD video with
copyright, while the low-resolution, snowflake point or no video with normal audio; But picture is normal with PC
source, pls programming the “HDCP code” or replace the new main board. (Pls refer to the “HDCP code”
programming as below)
58
I. Prepare condition:
1. Prepare one PC and the system is WIN98/NT/2000/XP, make sure the PC have Print Port.
2. Install Port95nt Software, the way of the install Port95 (LPT PORT drive):
a. selects the software of Port95nt.exe, and run it,
b. After install ok, restart the PC.
3. Connect the cable and Jig:
a. Use the Print cable to connect the PC and HDCP card.
b. Connect the VGA cable with the ISP record card, the picture of Print cable, VGA cable and ISP card as below:
59
Step2. Click “Load HDCP…”. choose the corresponding “*.BIN” by scaler IC (MST Scaler) ,then click “Open” as
below.

Install software:
Note:Burning softsare and EDID data must be put in the same folder as follow picture:
65
1.Double-click the icon “ ” to install Port95nt print driver, and then restart the computer.
66
4.Input same SN twice and date. Click “Pragram” to burn. When appear “pass” as follow picture that burning is
successful.
67
68
Click “Read both” show as follow picuture..If read SN and model name are same as before inputing as before
that burning is successful.
69
Appear fault as follow,please check the connection of VGA and the connection of DVI
Note:
If the burn software is unsuccessfulll, appear fault:
1. For VGA,the resolution will be not the best achieve.
2. For DVI,No picture,no sound.
If program failed, in VGA mode, you can’t use the optimal resolution.

B. 7300K color
Normal color temp. parameter is x=301±30 ,y=317±30
C. 9300K color
Cool color temp. parameter is x=283±30,y=297±30
D. sRGB color:
sRGB color temp. parameter is x=313±30 ,y=329±30
3. Bias adjustment:
Set the Contrast to 50; Adjust the Brightness to 90.
4. Gain adjustment:
A. Adjust Warm (6500K) color-temperature
1. Switch the chroma-7120 to RGB-Mode (with press “MODE” button)
2. Switch the MEM.channel to Channel 3 (with up or down arrow on chroma 7120)
3. The LCD-indicator on chroma 7120 will show x=313±30 ,y=329±30
4. Adjust the RED on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN on factory window until chroma 7120 indicator reachedthe value G=100
6. Adjust the BLUE on factory window until chroma 7120 indicator reached the value B=100
7. Repeat above procedure (item4, 5, 6) until chroma 7120 RGB value meet the tolerance =100±2
72
73
2. Use hand to draw the decoration piece to take the top of it apart from the block slot of front frame. Use the same
method to take apart the other side.
3. After the top of the decoration piece come out from the front frame block slot, then detrude the bottom of the
decoration piece horizontally.
74
5. Overturn the monitor, there are blocks fix the frame and iron plate, so should use hand draw the frame to apart
them.
75
76
9. Take off the screw which used to fix the iron plate and Panel, and take apart the iron plate.
10. According to the different defective area, take off the screws to get the relevant part to maintain.
Notice: When fix the decoration piece, please pay attention to the “UP” logo side should towards to the top.
