Analog power saving mode?...

as you have just said safe mode will be your next step.

Hello,

The most common cause of power loss on the W1952TQ is a failure of the filter capacitors on the power supply board. This is the same board used in several of the LG monitors including the W2252. You can repair the monitor by replacing the capacitors on the board. Here is a link to a repair kit with the correct capacitors to rebuild the power board.

bad caps in you power board or your vga needs changing

According to the Owner's Manual (http://www.lg.com/us/support/product/support-product-profile.jsp?customerModelCode=W1952TQ-TF.AUSMAPN&matchedModelCode=1000004017&searchEngineModelCode=W1952TQ&initialTab=documents&targetPage=support-product-profile#), unplug it from its power source, then wipe it with a slightly damp (not wet) cloth; & don't spray the screen with an aerosol because the overspray could cause electrical shock. I suggest that with it unplugged from its power source, use monitor wipes (available at most office supply stores). Then plug it into its power source away from souces of water, & you're done.

your LG monitor is bad then if you put another monitor on the computer and your getting video. Just as a last resort, you might want to put the LG monitor on another computer and if it stays in sleep mode then you know for sure at that point, the monitor is bad.

If its going to analog power saving mode, that is what its supposed to do when it does not get a recognizable connection from a computer vga port. I would suggest coming back on with some more information about your computer and suggest testing another screen on your pc.

reinstall windows

may try uninstalling the hardware and reinstalling it, i mean in device manager not physically

i had the same problem.
connect the monitor with the analog cable and shut down your pc.
while it is off unplag the analog cable and place the digital one(dvi).
this should fix your problem m8 ;)

I have an LG Flatron 19" black w1952TQ that I bought on 2 Apr 2008; when it goes into sleep mode, will not recover. Did the online troubleshooting, reseting things, unplugging/replugging all cables, nothing works except restarting the computer, and that only works until it sleeps... Read more
