Check the power supply caps for leaking/bulging tops first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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 SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Monitor will not stay powered up


It is possible that the monitor is going back into "Sleep mode" meaning it is not detecting a valid signal from whatever device it is plugged into. I would try replacing the cable that is connecting the monitor to the PC or Console. As a trouble shooting step try pulling up the "Menu" on the monitor itself by pressing the "Menu" button on the front panel of the monitor, if this does come up then we can say that the LCD itself is most likely working.

My LG flatiron W1943TB turns on, says analog power saving mode, goes black and then the power button flashes.. but the monitor is hooked up to my dell notebook bc my LCD died


Hi erin mckinle,
That is probably it's, uh, analog power saving mode. When the screen goes black and the power button flashes, make some mouse gestures or hit some keys that would not affect anything (try spacebar). That should bring up the screen. If you think it goes into power saving mode too fast, go to Control Panel --> Power Options, and change the values. Hope this helps.

My Samsung SyncMaster 215TW Monitor only flashes on for a second when I hit the standby button, and wiggle the mouse. I can't get the monitor display to stay on. Can you help?


If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.

I hit a button on the bottom of my monitor and now my screen is black and the light is flashing blue? what do i do


I have had the same problem with two of these monitors. If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.

Monitor shuts off during boot. Let the machine boot full up, hit the power button, the monitor flashes windows for a split second, and goes back to power saving mode


Hey there Celius,

Chances are the 'Refresh Rate' somehow got set too high for the monitor. On flatscreens , the result is a black screen.

If you have an old monitor (crt type) hook that up temporarily and reboot.
  • Right Click the Desktop
  • Click Properties
  • Click Settings
  • Click Advanced
  • Click Monitor
  • Lower the refresh rate or set at optimal
  • Check the box 'Hide refresh rates this monitor can't display'
Shutdown, Switch back monitors and try it now.

Good luck
Mike

Image go off


I have had the same problem. I've just managed to get the monitor working again by VERY QUICKLY navigating through the monitor setup menu to the 'factory reset' option and hitting reset before the screen had a chance to blink off.

The problem I had is that the monitor suddenly goes black, but will come on for five seconds if I switch it off and on with the power button.

In that five seconds, I had to...
>Hit the menu button
>then hit the '+; button once
>then hit the menu button again
>then hit the '-' button
>then hit the menu button one last time

The above brings up the menu, scrolls up off the top of the list to the last item on the list (Factory Reset), selects Factory Reset, selects 'All settings' and resets the monitor.

I don't know if this is a permanent fix, but it just worked for me and mine has been doing this intermittently for the last week.

Give it a try, it's frustrating and will take a few tries, but it can't hurt.
