1.No Screen Appear

Measured CN201 pin5/6 = 12 V?

Measured CN201 pin 9/10= 5V?

Measured U202 pin 2= 3.3V?

Check Correspondent component.

Is there any shortage or cold solder?

Yes, all DC level exist

Disconnected the Signal cable (Loose the

Yes. There have OSD show

Connected the Signal cable again,

Signal cable), Is the screen show “Cable Not

Connected”?

No, nothing is show Led Orange

Check LED status.

Check Power switch is in Power-on

Led Green

Replace U601

Connected the Signal cable again status, and check if Power switch had been stuck?

Led Green

Check the Wire-Harness from CN503

Check Panel-Power Circuit Block

OK, Keyboard no stuck

OK, Wire tight enough

Measured RGB (R301, R302, R303) H,

V Input at U401 pin 37,38, was there have signal?

OK, Panel Power OK

OK, input Normal

Check U401 Data-output Block

OK

Measured Crystal X401 (14.318MHz)

OK, clock normal

Replace Power board and Check

Inverter control relative circuit

Re-do White balance adjust

Replace U401 (TSU16AK)

OK

Led orange

Check Correspondent component short/open

(Protection Diode)

Note: 1. If replace “MAIN-BOARD”, Please re-do “DDC-content” programmed & “White-Balance”.

NG

2. If replace “Power Board” only, Please re-do “ White-Balance”

9. White- Balance, Luminance Adjustment

Approximately 2 Hours should be allowed for warm up before proceeding White-Balance adjustment.

Before started adjust white balance, please setting the Chroma-7120 MEM. Channel 9 to 9300

0

K colors; MEM.

Channel 10 to 7500

0

K; MEM. Channel 11 to 6500

0

K colors; MEM. Channel 3 to SRGB.

9300 parameter is x = 283, y = 297, Y = 180 ±20 cd/m

2

,

7500 parameter is x = 299, y = 315, Y = 180 ±20 cd/m

2

,

6500 parameter is x = 313, y = 329, Y = 180 ± 20 cd/m

2

,

SRGB parameter is x = 313, y = 329, Y = 180 ±20 cd/m

2.

And set the timing to the optimal resolution and full white pattern.

How to setting MEM.channel you can reference to chroma 7120 user guide or simple use “ SC” key and “ NEXT” key to modify xyY value and use “ID” key to modify the TEXT description Following is the procedure to do white-balance adjust.

Press MENU (about 10 second), along with re-plug power cable will activate the factory mode.

Gain adjustment:

Change the mode of Gray 32.

Move cursor to “-Factory Setting-” and press MENU key to enter this sub-menu,

Move cursor to “ Factory” and press MENU key,

Move cursor to “ Auto Level” and press MENU key to adjust Gain and Offset automatically,

And change to the full white pattern.

a. Adjust Color1 (9300

24. Repeat above procedure (item 5,6,7) until chroma 7120 RGB value meet the tolerance =100±2

c. Adjust sRGB (6500

0

K) color-temperature

1. Switch the chroma-7120 to RGB-mode (with press “MODE” button)

2. Switch the MEM.channel to Channel 01 (with up or down arrow on chroma 7120)

3. The LCD-indicator on chroma 7120 will show 6500 parameter is x = 313, y = 329, Y = 180 ± 20 cd/m

2

4. In sRGB sub-menu, adjust C to 85,adjust L to 100,

5. Adjust the RED on OSD window until chroma 7120 indicator reached the value R=100

6. Adjust the GREEN on OSD, until chroma 7120 indicator reached G=100

7. Adjust the BLUE on OSD, until chroma 7120 indicator reached B=100

8. Repeat above procedure (item 5,6,7) until chroma 7120 RGB value meet the tolerance =100±2

Move cursor to “ Exit/Save” sub-menu and press MENU key to save adjust value and exit.
