Possible Cause and Solution
• Check if the LCD monitor is turned ON.
• Check if the power adapter is properly connected to the LCD monitor.
• Check if the power cord is plugged into the power outlet and to the
power adapter.
• Check if the LCD monitor is properly connected to the input source.
• Check if the input source is turned ON.
• Check if the input source is in standby mode, move the mouse or press
any key to wake it up.
Note: Do not connect the USB cable to the LCD monitor in order to
charge your laptop. Doing so will disable the LCD monitor to
wake up from standby mode by simply touching the screen.
• Check to see if the resolution of your computer is higher than that of the
LCD monitor.
• Reconfigure the resolution of your computer to make it less than or
equal to 1024 x 768 (for TX-1502), 1280 x 1024 (for TX-1702/1902), or
1920 x 1080 (for TX-2202).
• For VGA input, adjust the "H-Position (Horizontal Position)" and "V-Position
(Vertical Position)" settings in Picture menu. Refer to page 27.
• For VGA input, run the Auto Adjust function in Picture menu. Refer to
page 28.
• There are millions of micro transistors inside the LCD monitor. It is
normal for a few transistors to be damaged and to produce spots. This
is acceptable and is not considered a failure.
• Turn off the LCD monitor for extended periods of time.
• Use a screen saver or a black and white image and run it for extended
periods of time.
• This normally happens when the LCD monitor is moved from a cold
room to a hot room temperature. Do not turn ON the LCD monitor, wait
for the dew condensation to disappear.
