Hi. I have a FLATRON W1934S computer. Every time I switch it on it says "power saving Mode". How can I fix it?


Hello, I didn't understand the problem.
1.After switch on and it goes to power saving mode , which can be visibly seen by changing the color of power led from green9or blue) to yellow.

First thing to be done is when it goes to that state "power saving mode" remove the video VGA cabl , and if the unit gives video message "no video signal" which stays for a while and usually goes again to power saving mode , this is OK,
So if there is no video signal on input it should work like this. so you have to check you PC.
Another way is to use laptop or other PC to check the monitor itself.

Hope this helps a bit

When I start the computer the Windows XP Logos light up on the Monitor (HP w1907) when the computer starts the Logo disappears and the monitor goes to sleep


If this monitor (HP w1907) is going into sleep mode the normally blue power led will change to yellow. This indicates loss of video signal or possible out of range resolution. If the picture goes dark and the power lite stays blue, you have a backlight malfunction. It can be an inverter power fault but this model mostly has worn out backlights causing a shutdown condition.

LG LCD Monitor won't exit Power Saving Mode


Does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/motherboard are defective in some ways. Try using a different monitor.

If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/Win7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there. Then check and see if your LG monitor works on it.

If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PCs video card/motherboard, not the monitor.

Hope that helps. Good luck

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 ?

The monitor doesn't receive the signal from the PC. It is either the PC not booting up or the VGA coard is faulty. Change the VGA coard. or try reseting the VGA cord.
