Display Problems
Nothing appears on the screen.
During operation, the screen may automatically turn off as a result of
power management. Press any key to see if the screen comes back.
The brightness level might be too low. Increase the brightness.
The display output might be set to an external device. Switch the display
back to the internal LCD.
The characters on the screen are dim.
Adjust the brightness and/or contrast.
The display brightness cannot be increased.
As a protection, the display brightness will be fixed at a low level when
the surrounding temperature is too high or too low. It is not a
malfunction in this situation.
Bad dots appear on the display at all times.
A small number of missing, discolored, or bright dots on the screen are
an intrinsic characteristic of TFT LCD technology. It is not regarded as an
LCD defect.
Clouding (or called “mura”) happens on the screen when you exert
forces on the left or right side of the LCD frame.
This is a normal phenomenon, not a defect.
The display has a slower response time in low temperature
environments.
The response time of LCDs can be affected by low temperatures. This
does not mean the LCD is defective. The LCD will resume normal response
time after returning to room temperature.
