[From the Recovery flowchart (1-1)]
Display RST MASK 09 (red 2). / [MKS S59] Note: Disregard the discharge that may appear during voltage-change setting.

Set VOL OFFSET to the setting value 240. / [VOF 240] Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell).
B

� This setting becomes VOL OFFSET_max1.

VOL OFFSET_max1
Note: Make a note of this VOL OFFSET_max1 value.

VOL OFFSET_max1

107?

No

Replacement of abnormal circuits or re-replacement of the panel required

Yes Display RST MASK 10 (green 2). / [MKS S60]

Set VOL OFFSET to the setting value 240. / [VOF 240]
C

� This setting becomes Gradually decrease the VOL OFFSET value until disappear the discharge (dead cell). VOL OFFSET_max2.

VOL OFFSET_max2
Note: Make a note of this VOL OFFSET_max2 value.

VOL OFFSET_max2

107?

No

Replacement of abnormal circuits or re-replacement of the panel required VOL OFFSET_max

Yes Choose the lower value between VOL_OFFSET_max1 and VOL_OFFSET_max2, and set it as VOL_OFFSET_max.
D

Recovery flowchart (1-3)
[From the Recovery flowchart (1-2)]

Is the VOL OFFSET_max value minus the VOL OFFSET_min value greater than 96? Yes
E

No

Replacement of abnormal circuits or re-replacement of the panel required

Are the VOL OFFSET_max value 165 or greater and the VOL OFFSET_min value 069 or less? Yes Set VOL OFFSET to the setting value 117. / [VOF 117]

No

VOL OFFSET_max

165?

No

Yes Set VOL OFFSET to the setting value VOL OFFSET_max minus 48. Set VOL OFFSET to the setting value VOL OFFSET_min plus 48.

F

Determine the current VOL OFFSET setting value as the final value.
