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.
