There must be no abnormality when 1500VAC is applied for two seconds between both ends of
the AC input terminal and chassis, and between the DG coil terminal and chassis.
2.5.1.2 Grounding conductivity check
Check that the resistance value is 100m
¶
or less when 25A is passed between the AC input
terminal grounding GND and chassis GND.
2.5.1.3 Degaussing coil operation
Confirm that when OSD DEGAUSS is executed, the picture vibrates and then stops.
2.5.1.4 IPM (POWER SAVE) function operation (Set the AC power input to 230V)
Use the full white pattern without R, G, B signals.
