Hi Joeteena,
I think that there is dust under your touch buttons.

How do i change sleep mode


Sleep Timer Mode

The Sleep Timer mode is an energy-saving feature that enables you to set a time for the monitor to
power on and off at the same time every day. This also extends the life of the backlight bulbs in the
monitor. The Sleep Timer has five settings:
? Set Current Time
? Set Sleep Time
? Set On Time
? Timer: On/Off
? Sleep Now

To set the timer:
1. Press the Menu button on the monitor front panel to display the OSD Menu.
2. Scroll down and highlight Management.
3. Press the OK button to select Management.
4. Scroll down and highlight and select Sleep Timer > Set Current Time.
NOTE: You must set the current local time before you reset the time for Sleep Time or On Time. Note that the time is displayed in a 24-hour clock format. For example, 1:15 p.m. is displayed as 13 hours 15 minutes. A power failure or loss of power to the monitor will cause the timer to reset to 00:00. If this occurs, you will need to reset the sleep timer mode.

5. Press the OK button once to enter the adjustment mode for hours.
6. Press the - (Minus) or + (Plus) button to adjust the hour.
7. Press the OK button again to enter the time for minutes.
8. Press the - (Minus) or + (Plus) button to adjust the minutes.
9. Press the OK button to lock in the time chosen.
10. After setting the current time, the highlight automatically skips to Set Sleep Time. Repeat steps 6 through 9 to set Sleep Time.
11. If you do not want to set Sleep Time, press the OK button twice, then select Save and Return to exit the menu.
12. After setting Sleep Time, the highlight automatically skips to Set On Time. Repeat steps 6 through 9 to set On Time.
13. Set the Timer mode to On to activate the Sleep Timer settings.
14. When you are finished, select Save and Return to exit the menu.

The fifth selection, Sleep Now, turns the monitor backlights off immediately and stays in sleep mode
until the next On Time activates or a monitor button is pressed.

Goes black, blinks and sometimes works fine


Sometime the cross-talk of signals is caused by the wiring behind the computer, touching. Separate the wiring.

My LG monitor blacks out intermittently when warm, I have tried it on another computer so it is a fault with the monitor. It blacks out every few seconds, sometimes it takes longer. It is 2 years old.


after blackout, check the screen as that. look in to the monitor in side angel,
and if you can see darken live image in that and its working. in that condition, your
LCD panel is working and the problem is no light.
in that case you need to repleace or repair the " inverter unit " in that monitor.
that unit makes the high voltage for back light.

after blackout , you cant see any darken image like as that, and or totally power
goes off , that is different problem. for solve that need advance trouble shooting
and can be need advance repair.
