LG Flatron L1720P Loses Display

My 1720P is approx. 3 yrs old. After about 10 min operation the display suddenly goes black. I hear a small click when that happens. I can still see a slight "ghost" t the display. If I turn the monitor off & wait a few minutes the display returns, but then will go dark again after several minutes. This process repeats w/ the ever shortening intervals. Any ideas as to the problem & whether it's a reasonable ($$-wise) fix? --It just happened adain!

    From the description in the previous posting, it sounds almost exactly like the problem I'm experiencing with my LF Flatron L1720P. Now, the monitor doesn't even turn on. I just hear the clicking sound but nothing happens.

    Monitor is black but the computer is working. I get a blue blinking light on the monitor power on/off switch. Sometimes the blinking alternates between blue and yellow. Can't get a picture back.

The backlight inverter board is defective or a high voltage cable going from the inverter output to the lamps is damaged or touching ground.

LG Flatron l1515s which is giving Out of Range 64.0kHz / 60Hz and can not even give setup menu. Please help.

This is not a setting on your monitor. It is a setting on your operating system. The display settings needs to be set to a 60Hz refresh rate.

Hook up your old monitor and right click on desktop --> properties --> and then to display and advanced settings. You can then set it to proper refresh rate and plug the new monitor in.

Not able to use full screen

This sounds like bad resolution is set on your computer. The LG 22" FLATRON monitor has a native resolution of 1680 x 1050. However, your video card may not support this so you can also try any other 16:10 resolution like 1440 x 900.

To change your resolution in Windows XP:
1. Access the Control Panel.
2. Choose "Display".
3. Click the "Settings" tab.
4. Under "Screen resolution" move the slider to a 16:10 resolution like 1680 x 1050 or 1440 x 900.

If you computer does not support higher resolutions, you may consider replacing your video card to take full advantage of your nice 22" Flatron monitor.

If I can further assist you, please let me know.

Hooked up a used 17" LG Flatron L1720P flat Panel. When I turn it on it says Power Saving Analog Mode and goes black, no instructions with it.

Make sure your power cables are connected properly. Sounds like it's not getting any video data from the graphics card.

If it is not your graphics card, It could be a dead monitor.

Digital power saving mode

Are you sure someone hasn't changed the power setting in windows. I've seen similar tricks pulled by so called mates. :-) If windows is OK then check the manual for the monitor and if you still can't crack it take it for a ride to the repair shop. It is under warranty after all. BMW
