Your LG flatron(L222WS) widescreen go to “power saving mode” because it cannot detect power signal from your computer. Check the connection on the back of your LCD monitor and on back of your computer please make sure that they connected to the connector properly, If connected properly then in the case your computer itself will not boot. Try to connect some other monitor, If monitor getting ON and still not coming on screen then take your monitor to the service center . It may be some motherboard, graphic card or some processor issue.
I think there is something wrong with your video card. Check the display setting of your video card. This can be done by right clicking on the desktop and selecting properties. Then go to setting button and click advanced. If this does’nt work check the power cable, make sure you are using the correct video cable and input source. Try to use different power cord but it should be in working condition, If you use an adapter for it, verify that adapter is working.
If your monitor goes into power saving mode after booting then you can turn this function off by clicking start and then run button, now at the drop down box, enter the “powercfg.cpl” and click ok. You can also use control panel and then select Power option icon. Once you enter into power option property turn the monitor timing off by selecting “never”. You can also turn off the power from BIOS setup. Better you use this. If this does’nt work visit service center of your monitor.
It sounds like LCD isn't getting a signal from the computer. Check the connection or replace the cable if you have. you may also have a problem with the graphics card on your computer. Try to take your lcd, and plug it into a different computer. If this does’nt work then there must be a problem in your video card, Check your video card or visit service center of your LCD.
