For white balance adjustment, adjust the offset values on pages 11/21.

[Condition of the unit for inspection] : Modulated light (+16)

                                                                     AV MODE: DYNAMIC

                                                                     Active Backlight: OFF

                                                                     OPC: OFF

                                                                     Asing Time: Min, 60 minute

[Input signal condition]                     : HDMI 1080i 15IRE (LO), 78IRE (HI)

[Adjustment reference device]         : Minolta CA-210

[Adjustment procedure]

1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/21 of process adjustment)

The signal of 78IRE is input.

2) Read the value of the luminance meter. x=0.272, y =0.277

3) Change R_GAIN (HI)/ B_GAIN (HI) (Adjustment offset value) on page 11/21 of process adjustment so that the values of the luminance meter

approach x=0.272 and y =0.277.

(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R or B must be fixed.)

4) Display the adjustment status of the current R/G/B_GAIN (LO).

The signal of 15IRE is input.

Change R_GAIN (LO)/ B_GAIN (LO) (adjustment offset value) on page 11/21 of process adjustment so that the values of the luminance meter
approach x =0.272 and y = 0.277.

5)  Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.

[Adjustment reference standard value]

Adjustment spec 

± 0.002       Inspection spec ± 0.004 (point LO)

Adjustment spec 

± 0.001       Inspection spec ± 0.002 (point HI)

6) After completing adjustments, set EEP SAVE (Page 21/21) to ON in the process menu to save the white balance adjustment value.

1. HDMI-CEC Inspection

After repairing the CEC function, check the operation about HDMI-CEC circuit.

2. CI card Inspection

After repairing the CI function, check that the DTV signal is received by inserting CAM.

And check the KEY certification by inserting CAM which is prepare for CI+.

3. LAN Inspection (NET)/test connectivity of SD card.

After repairing the LAN function, check the communication by connecting PC and LAN terminal.

And test connectivity of SD card.

4. 3D Check

5. IR communication Check/IR Emitter (Infrared light Output) Inspection.
