Cannot Turn LCD On

2010-11-03, 1:45 AM

I had touched the ON/OFF LCD and PC/HDMI-IN button on the far right bottom edge of my A300 monitor before the computer has time to fully booted up. It follows that the screen didn't lit up and when I touched the same button again, it flashed a sign of "no signal" but it was stil NOT on. The computer was running fine. How can I turn the LCD screen back on again. I cannot key in my password to log into the Windows, as the screen was totally dark. Thanks for any help.

Hi FB, hope your problem was automatically resolved when you rebooted the A300? The display should hv come On in PC mode. Else you can gently touch the same right-most feather-touch sensor (button), on the bottom-right edge of the LCD panel, and keep touching it with your finger tip for 2 secs; the display status will appear on the screen and you will see the current mode highlighted. Again v gently tap the sensor to toggle the display mode thru the other settings -> PC / HDMI-in / LCD-off


PC mode will take you to the regular Windows display; HDMI-in will show you a display if any video source is connected via an HDMI cable to the system's HDMI-in port; and LCD-off will turn-off the LCD panel. HDMI-in can even be viewed without booting-up the system (just keep the input power adapter switched On).


'No Signal' will flash on the screen when (a) display is in PC mode and the system hasn't booted-up; or (b) display is in HDMI-in mode and no video source is connected thru the HDMI-in port.


I hope this helps.
