Hello,

This type of problem is usually caused by a failure of the filter capacitors on the power supply board. The LG L204ws uses the AIP-0156 power supply which is the same board used in many of the LG monitors that were sold around the same time. Here is a link to a repair guide for the LG L226wtq model that used that board. The repair guide as pictures and videos showing how to open the unit and check the filter caps. There are parts lists showing what needs to be replaced too.

I hope this helps,

    I've already clicked No; and replied via email, explaining that I can't reply to the solution or post anything with long paragraphs in the message box. It seem that even my 'No' answer hasn't gone through too! Check out previous email from me, and your response to it.

    Thanks for the info... The monitor works when I have to turn PC off by power switch and reboot. I have to add; I had the exact same problem about 2 years ago when I was using vista, and I think it was to do with software, but cannot remember exactly. I think what had happened then; the PC had loaded the monitor as plug and play, but I also loaded the monitor driver that came on the lg disc; (version 1.0 for windows; win. xp, win. 98, 200; win. Me). So it could be compatibility issue. Monitor and PC were bought as a package with vista installed and the monitor worked ok; until I install the driver software from CD. I did solve the problem then, but I cannot remember what I did. The same problem only started again since I have upgraded to win 7 and done the same thing by loading driver on disc. I have a feeling it is not the right driver on the disc for the monitor. On the other hand; I think it could be a conflict between nvidia plug and play driver and the lg monitor xp driver.

    Fixed monitor going back into analogue sleep mode: It was a conflict between Nvidia driver & LG monitor driver on cd. LG informed me that my monitor (L204WS) is plug and play; so I uninstalled the LG driver.

SOURCE: monitor goes to sleep and won't wake up

Yeah, im not sure about how to fix the problem with it shutting down like that, but one option is to go under your control panel and taking off the sleep function, or putting it on a 4 hour timer so that doesnt go into sleep mode anymore. However, the problem is not your monitor but your computer. Id just take the sleep mode off, there is no need to have it on.

SOURCE: LG w2361vg sometimes get stuck in DVI Power Saving Mode

Maybe you can update your video card driver. My wife notebook is connected at times to my DELL17" flat screen and ever so often it cuts off in the middle of something. I update the video driver and reset the monitor to factory settings and it's working like a dream.
I suggest, you use the menu buttons on the LCD and reset it ot factory settings, and possibly update your video card.

Hello,
This usually indicates that the filter capacitors in the power supply are not working right. When the unit is turned on they should build up a charge that lets the board power up the monitor but when they start to go out it takes longer and longer to get the charge built up. Here is a link to information on rebuilding the power supply board by replacing the capacitors, this should get you back up and running.

If you have a problem getting into safe mode using windows Vista or 7, boot up your computer. As soon as it tries to start windows turn off the power. When you try to start it again it should come up with a menu asking if you want to use safe mode or boot normally. Select safe mode.

Try it on another PC, but more likely to be the problem in the power supply. Please post back when you try it on another PC.

LCD Flatron 21inch going into power save mode problem


this is not a problem with the monitor, it looks as your computer is not sending any video signals to the monitor thus it goes into saving mode. Take a look at the computer, check the video card. Pull it out then turn it on, turn it off again and place the video card where it should go then turn the PC on again. This should clue the OS to re-configure the video driver. Did you try another monitor ?

I had the same problem with my LG Flatron (not the same model as your one). I fixed it by connecting both the digital and analogue cables from the pc. Presumably, the problem occurs because the monitor is not receiving a digital signal.

LG Flatron L1710S Monitor stuck in Power Save Mode


Try wiggling the Cord on the backside of the monitor.. Not the Power Plug Cord, The Other Cord that attaches to the PC. Do this once the monitor turns off , grab ahold of the cord about 2 inches from the back of the monitor, then bend the cord to the right, keep bending from the right to the left a couple times to see if your screen comes back, if it does, than you have a Loose connection and this sometimes causes the Symptoms you are receiving.. Hope it helps.
