Hello,

That is a common symptom of a failure of the filter capacitors on the power supply board. When the filter capacitors go out the backlight can get power so there is light but the control board is not powered up so you get no picture. You can rebuild the board and bring the unit back to full working condition by replacing the defective parts. Here is a link to information showing what capacitors you will need to get to do the rebuild.

And here is a picture of what the AIP-0108 power supply board looks like

melrosebanjo, Your monitor will need to have some work done on it's "switch-mode-power-supply" and /or "INVERTER" circuit. After you view some vids at YOUTUBE that deal with replacing bad electrolytic filter capacitors and detecting poor quality intermittant solder joints. Search for vids of "LCD monitor repair" "LCD monitor disassembly" !! Learn what are the major causes of LCD BLACK screen problems. Learn the difference between BLACK AND BLANK screens.

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, 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 LG and all other 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.

Try it with another PC first, if still not working, then start looking at the power supply DC filter caps first.

LG Flatron L177WSB-how would I use my newly purchased unit after switching it on, LG logo appears followed by the Power Saving Mode it all goes black on the screen.


Hi, the Power Saving Mode, turns the screen off to conserve energy. On the remote, press Menu, and scan to Power Saving Mode. You can change the amount of time, when the Screen turn-off, the TV shut-off etc. You can set the time to (5 min) to, (never, turn-off). This should help with your problem. Thanks paul7of9
