[Contents]
Various monitor side adjustments can be made manually.
(1) Lamp error reset (Done automatically with presetting)
Set 0F 00 0 in the 1st line, and then set 1 into the least significant bit. Upon this setting, the “lamp error” is
reset.
(After reset, 1 in the least significant bit will not become 0 automatically.)
After reset, switch off the power once and confirm that the system can be restarted in normal mode.
(2) Monitor G/A test pattern reset
Set 00 10 00 in the 3rd line, and then set 1 in the 4th line. Upon this setting, the blue screen appears. Thus
the test pattern in the monitor process adjustment is reset.
(After reset, the fourth line will not become 0 automatically.)
After reset, switch off the power once and confirm that the system can be restarted in normal mode.
