Look at the caps in the power supply first, that will be the start.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed HP monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

How do you set the minutes on the clock?


There are two ways to set the clock on your coffee maker. 1- When you initially plug in the coffee maker, the unit will beep and "12:00" will flash on the LCD display for a few seconds. Press immediately the h/min button (o) to set the current hour. If "12:00" starts to flash, press the PROG button (n) for a few seconds until the "12:00" flashes again. Then press the h/min button (o) to set the current hour. There are AM and PM indicators on the top right side of the LCD screen. To set the current minutes, press the PROG button (n) and then press the h/min button (o) until the correct minutes appear on the LCD display. After 5 seconds, the unit will beep and the time will stop flashing. 2- At any other time, you can set the clock or change the set time by pressing and holding the h/min button (o). The unit will beep and "12:00" will flash on the LCD display. Use the h/min button (o) to set the current hour. There are AM and PM indicators on the top right side of the LCD screen. To set the current minutes, press the PROG button (n) and then press the h/min button (o) until the correct minutes appear on the LCD display. After 5 seconds, the unit will beep and the time will stop flashing. Notes: Your clock has now been set and will continue to keep the correct time, even after the coffee maker has been shut off. Unplugging the coffee maker or a power failure will reset the clock to 12:00 AM. Repeat the instructions above to reset the clock

Display Shutdown After Few Seconds To Few Minutes


Hook a spare monitor to the computer to rule out the video graphics card in the computer, and sub another video cord from the computer to the monitor if possible to check your LG monitor, If the display shuts down and power light changes colour or goes out it is a power supply board, one or more capacitors open causing the power to fail, sometimes the top developes a bulge making it easy to spot.

Lcd monitor shutdown a few seconds after it is


If this is happening without it being plugged into anything; just the monitor itself; likely it's toast. Now, be aware that some monitors WILL shut themselves "off", or what looks like off, whenever there is not a signal. If you are using a computer, try a different computer and see if it works there.

If it is happening regardless, it's likely a P/S issue and not economically feasible to fix. With the price of nice LCD monitors nowadays, you'll be way better off shopping for one online.

The display turn off after few minutes (blank screen, no message). When it does that, the power led stay green. When I turn it off and on, the display work again for a few minutes and the same problem...


jackperson, Might be internal problem with the units power supply (ac line in to DC conversion) having shutdown issues. You will need to do some reading in my fixya profile for a while and then you will know what to look for inside unit. If not into electronic repair stuff, skip the reading and trade-in unit for new, if current unit is 4, 5, 6 years old. 12fixlouie

You have either a short in the cable, or your display screen(if it's CRT) is dying.

Display goes black after 5 minutes


Repairing the DELL E171Fpc LCD Monitor with the complaint of display shutdown after few seconds (power LED still on) was not difficult. Normally when this type of problem happens, we would first suspect the inverter board, then the filter capacitors and lastly the main board. A defective in one of the lamps and a faulty TL1451AC PWM IC or inverter ic may caused the display to shutdown as well. If the lamp is defective, it will send a feedback to pin 3 or 14 of TL1451AC IC and caused it to stop producing output signal thus the display just shut off once you switch it on.
