A

(From 1 )
(Check Vofs_max1 with the red 760 signal.) Perform aging with RST MASK 01 (white) displayed for 3 seconds: MKS S51

Set to RST MASK 17 (pale purple).

MKS S67

Set VOL OFFSET to 024 (15 [V] ).
B

VOF 024

Are there any dark cells? Yes Gradually increase Vofs data VOF ��� until dark cells disappear (Vofs should be 255 (60 [V]) or less).

No

Set Vofs_min1 to 024 (15 [V]).

Note: This setting value becomes the value for Vofs_min1.

Vofs_min1

[STEP]
Note: Take note of the value for Vofs_min1.

Is Vofs_min1 144 (38 [V]) or smaller?
C

No

Replace the panel again or abnormality in circuits

Yes

Return the Vofs value to the tentative voltage setting.

VOF ���

Note: for checking the lower limit of Vofs accurately. This is

(Check Vofs_min2 with the sky color signal.) Perform aging with RST MASK 01 (white) displayed for 3 seconds: MKS S51

D

Set to RST MASK 16 (sky color).

MKS S66

Set VOL OFFSET to 024 (15 [V] ).

VOF 024

Are there any dark cells? Yes Gradually increase the Vofs data until dark cells disappear (Vofs should be 255 (60 [V]) or less).
E

No

Set Vofs_min2 to 024 (15 [V]).

Vofs_min2

[STEP]
Note: Take note of the value

Is Vofs_min2 144 (38 [V]) or smaller? Yes

No

Replace the panel again or abnormality in circuits

for Vofs_min2.
