Planar PT1503NT ユーザーズマニュアル

If there is no display on the LCD, refer to the following: 

1.  Make sure that the power indicator on the LCD monitor is lit, 

all connections are secure, and the system is running on the 
correct timing. Refer to the Addendum for information on 
timing. 

2.  Turn off the LCD monitor and then turn it back on again. Press 

the OSD Menu button (refer to Chapter 2) once and then press 
either Adjustment Control button several times. If there is still 
no display, press the other Adjustment Control button several 
times. 

3.  If step 2 doesn’t work, connect your PC system to another 

external CRT. If your PC system functions properly with a CRT 
monitor but it does not function with the LCD monitor, and the 
LCD monitor’s power LED is blinking, the output timing of the 
PC’s VGA card may be out of the LCD’s synchronous range. 
Change to one of the alternate modes, listed in the Addendum, 
or replace the VGA card and repeat steps 1 and 2. 

4.  If the power LED is not lit, check that the AC power connector 

is securely connected. Verify that the AC adapter LED is lit. If 
the AC adapter LED is not lit, please contact Planar for 
assistance..
