the monitor is going into power saving mode ... it can happen if it is not receiving any signal from the pc ( pc is not running or booted properly, bad video cable connection monitor to pc) or the pc is itself in suspend/standby mode.

THe AC adapter (power supply) for my Princeton VL173 went bad. I discovered it was the PS and not the display by plugging in an old adapter from an HP printer that I had replaced. The input plugs matched and the power out profiles were nearly identical Only very minor differences). It was just a stab in the dark, but it works! Now my display is 12 years old and still going strong. I hope this helps.

check to make sure none of the pins on your vga cord are bent. if ok check to make sure your video card is fully seated. also if your computer has built in video and also has a video card in it try other vga output

Blue tint means taht you may have bad video cable or bent pins, check both ends of the video cable first and also try flexing the video cable to see if the problem will gome and go.

sounds like its set in the bios to boot on a second video card. At startup hit f2 (usually) then find the first boot setting and make sure its booting to the correct card. I

If your trying to wake your computer/monitor up try pressing a button on your keyboard or move your mouse. This should wake up both your monitor and computer.

The 5vdc for the logic is probably OK (taht is where the power LED gets the power from)
It is either the power issue in the 16~18vdc power supply due to bad caps with domed tops for the inverter circuits, or bad components (transistors, transformer, etc) in the inverter circuits.
See my pictures here: http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL1918W/
Make sure to replace them in a set.
If you are going to DIY and already try the monitor with another PC, 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 (they should be replaced in a set), 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 PRINCETON monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hi,
Please check if all the cables are properly plugged in. If yes, then remove the vga cable with the blue plug from the back of the monitor, make sure that you do not remove the power cable. if you see monitor self test or any colors on the screen it means that the monitor is fine. but, if there is no display still you need to change your monitor.
then the problem is in the tower, please check the power supply if it is working or not. If yes, the problem is either with the mother board or the memory.

Thanks and Regards
