LD 500/500V User Manual 
Troubleshooting 
This LCD monitor has been pre-configured using factory standard VGA timings. Due to the 
output timing differences among various VGA cards in the market, users may initially 
experience an unstable or unclear display whenever a new display mode or new VGA card is 
selected. 
 
Important: 
This LCD monitor supports multiple VGA modes.     
Refer to the standard Timing Table for a listing of modes supported by this LCD monitor. 
 
Problem 
Points to check with possible solutions 
No power 
 Make sure the power button is ON 
 Make sure the power cord is firmly connected to the back 
  of the monitor and to a power outlet. 
Power on but no screen 
image 
 Make sure the signal cable supplied with the monitor is 
  fully inserted into the video output port on the back of the 
  computer. If the other end of the signal cable is not 
  attached permanently to the monitor, tightly secure it to 
 the 
monitor. 
 Adjust brightness and contrast. 
No signal Input 
 Check that the PC is turned ON 
 Check that the signal cable is properly connected to the 
  graphics board or PC. 
 Check that the graphics board is correctly inserted in the 
  PC.   
Out of range error 
message appears 
 Use the graphics board’s utility software to change the 
  frequency setting. (Refer to the manual for the graphics 
 board.) 
 For Windows 95 users (OSR 2.0 or newer) or Windows 98, 
  restart the PC in a safe mode and change the frequency in 
  the “Display” setting for the PC. 
Vertical bars of distortion 
appear 
 Make adjustments to the “Image”, “Clock” setting in the 
 OSD 
menu. 
Horizontal bars of 
distortion appear. 
 Make adjustments to the “Image”, “Phase” setting in the 
 OSD 
menu. 
The screen has defective 
pixels (e.g. slightly light or 
dark) 
 This is due to the characteristics of the panel itself, not 
  the LCD monitor. 
Incorrect display of colors 
 If any colors (red, green, or blue) are missing, check that 
  the signal cable is firmly connected. Damaged pins in the 
  cable connector may also result in a faulty connection.
